  The motor device 1000 includes an SR motor 100 and a motor control device 1 that supplies a control current to the SR motor 100. First, the structure of the SR motor 100 will be described. The SR motor 100 includes a stator 110 and a rotor 120 that is rotatably disposed inside the stator 110. The stator 110 includes a stator core 111 and a winding M wound around the stator core 111, and the rotor 120 includes a rotor core 121 and a shaft 124 as an output shaft that is fitted into the rotor core 121. .

  The stator core 111 includes a substantially annular stator core main body 112 and six stator salient poles 113 integrally formed at an equal pitch from the stator core main body 1112 inward in the radial direction. Includes a U-phase, V-phase, W-phase, U-phase, V-phase, and W-phase coil (U, V, W, U, V, W) that form winding M in order in the circumferential direction. Has been. The rotor core 121 includes a substantially annular rotor core main body 122 and eight rotor salient poles 123 integrally formed at an equal pitch from the rotor core main body 122 toward the radially outer side.

  The U-phase, V-phase, and W-phase coils (U, V, W) forming the winding M have their end portions (U1, V1, W1) connected to the connection point P, so-called star connection structure. It has become. Since it has such a star connection structure, at least two coils (U and V, U and W, and V) among the U phase, V phase, and W phase coils (U, V, and W) of the winding M are used. W) is supplied with a control current.

  Next, the motor control device 1 will be described. The motor control device 1 includes a rotation sensor Rs, current sensors (Us, Vs, Ws), a three-phase inverter circuit 10, and a control circuit unit 20. The rotation sensor Rs is attached to the SR motor 100, detects the rotation of the rotor 120, and outputs a rotation signal. The current sensors (Us, Vs, Ws) are the first to third control currents flowing through the end portions (U2, V2, W2) of the U-phase, V-phase, and W-phase coils (U, V, W). A current value is detected, and a voltage value corresponding to the detected current value is output. In the present embodiment, a resolver is used as the rotation sensor Rs.

  The three-phase inverter circuit 10 includes first to third half bridges (Su, Sv, Sw) connected in parallel to each other. The first half bridge Su includes a switch element UH and a switch element UL. The second half bridge Sv includes a switch element VH and a switch element VL, which are connected in series with each other, and the third half bridge Sw includes a switch element WH and a switch The device WL is provided, and they are connected in series with each other. Then, at the midpoints (u1, v1, w1) of the first to third half bridges (Su, Sv, Sw), the respective end portions of the U-phase, V-phase, and W-phase coils (U, V, W) (U2, V2, W2) are connected. The three-phase inverter circuit 10 is connected to the three-phase inverter circuit 10 with a power source BT that supplies current to the SR motor 1000 and a capacitor that smoothes the control current supplied to the SR motor 1000.

  In the present embodiment, the number of stator salient poles 113 around which U-phase, V-phase, and W-phase coils (U, V, W) are wound by concentrated winding is “6”, and the number of rotor salient poles 123 is It is set to a combination of poles that are “8”. Therefore, unlike the conventional SR motor, the control current is not supplied to the U-phase, V-phase, and W-phase coils (U, V, W) independently, that is, the U-phase, V-phase, and W-phase coils. By supplying a control current to two coils (U and V, U and W, V and W) of (U, V, W), the rotor 120 can be rotated and the SR motor 1000 can be operated. .

  Therefore, instead of using special switch means such as the switch means comprising three independent bridge-like switch circuits shown as the conventional example, as switch means for supplying a control current to the winding M of the SR motor 1000, 3 A phase inverter circuit 10 can be used. Three-phase inverter circuits are widely distributed and are inexpensive. Therefore, the cost of the motor control device 1 can be reduced. In addition, the three-phase inverter circuit has abundant performance specifications and is easy to use because there are many modules. Therefore, it becomes easy to change the specifications of the motor control device 1 according to the characteristics of the SR motor.

  Next, the control circuit unit 20 provided in the motor control device 1 will be described. The control circuit unit 20 includes position detection means 21, energization timing output means 22, current value detection means 23, current value selection means 24, current command value detection means 25, current value comparison means 26, duty determination means 27, PWM signal output. Means 28 and switch signal output means 29 are provided.

  The position detection unit 21 generates a rotation position signal based on the rotation signal supplied from the rotation sensor Rs, and outputs the rotation position signal. The current value detection means 23 generates current value signals (Iu, Iv, Iw) based on voltage values corresponding to the current values of the first to third control currents supplied from the current sensors (Us, Vs, Ws). Output. The target torque command value of the SR motor 1000 is supplied to the current command value detection means 25 by an accelerator or the like, and the current command value detection means 25 outputs a target current value corresponding to this target torque command value.

  Next, based on the timing chart shown in FIG. 3, the operations of the energization timing output means 22, the current value selection means 24, the current value comparison means 26, the duty determination means 27, the PWM signal output means 28, and the switch signal output means 29 are described. explain. In the figure, the relationship between the time t1 to t7 and the change in the electrical angle due to the rotation of the rotor 120 is as follows: time t0 to t1 (time t1 to t2, time t2 to t3, time t3 to t4, time t4 to t5, The relationship is shown in which the rotor 120 is rotated by an angle corresponding to an electrical angle of 60 degrees from time t5 to t6 and from time t6 to t7).

  The energization timing output means 22 outputs an energization timing signal (Uh, Vh, Wh, Ul, Vl, Wl) having a predetermined switching signal based on the rotational position signal output from the position detection means 21. The energization timing signal (Uh, Vh, Wh, Ul, Vl, Wl) includes an ON switching signal formed every 360 degrees of electrical angle and an OFF formed after 120 degrees electrical angle after the ON switching signal is formed. Has a switching signal. Further, in the present embodiment, the energization timing signals (Uh, Vh, Wh, Ul, Vl, Wl) are respectively formed in a predetermined order and an ON switching signal is formed every 60 degrees of electrical angle. Is set.

  In the present embodiment, for example, as shown in the figure, the energization timing output means 22 forms an “on switch signal” in the energization timing signal Vl and an “off switch signal” in the energization timing signal Wl at time t0. At time t1, an “ON switching signal” is formed in the energization timing signal Wh, and an “OFF switching signal” is formed in the energization timing signal Uh. At time t2, an “ON switching signal” and an energization timing signal Vl are formed. An “off switching signal” is formed. Further, at time t3, an “ON switching signal” is formed in the energization timing signal Vh, and an “OFF switching signal” is formed in the energization timing signal Wh. At time t4, an “ON switching signal” and an energization timing signal Ul are formed. "OFF switching signal" is formed at time t5, "ON switching signal" is formed in the energization timing signal Uh, and "OFF switching signal" is formed in the energization timing signal Vh. At time t6, "ON switching signal" is formed in the energization timing signal Vl. An “off switching signal” is formed in the “switching signal” and the energization timing signal Wl.

The current value selection means 24 is an energization timing signal (Uh, Vh, Wh, Ul, Vl, Wl).
On the basis of the current value signal, the current value signal (Iu, Iv, Iw) corresponding to the current value of the first to third control currents output from the current value detecting means 23 is converted into an electrical angle of 60 degrees. Select every output.

  In the present embodiment, for example, as shown in the figure, the current value selection means 24 is supplied with the “on switching signal” of the energization timing signal Vl or the “off switching signal” of the energization timing signal Wl at time t0. Then, the current value signal Iu is selected, and the current value signal Iv is selected when the “on switching signal” of the energization timing signal Wh or the “off switching signal” of the energization timing signal Uh is supplied at time t1, and the time t2 When the “on switching signal” of the energization timing signal Ul or the “off switching signal” of the energization timing signal Vl is output, the current value signal Iw is selected and output. Similarly, the current value selection means 24 selects and outputs the current value signal Iu at time t3, the current value signal Iv at time t4, and the current value signal Iw at time t5.

  In the current value comparison unit 26, a current value corresponding to the target current value output from the current command value detection unit 25 and the current values of the first to third control currents selectively output from the current value selection unit 24. The signals (Iu, Iv, Iw) are compared, and a difference signal corresponding to the difference current value is output.

  In the present embodiment, for example, the target current value and the current value signal Iu are compared from time t0 to t1, the target current value and current value signal Iv are compared from time t1 to t2, and from time t2 to t3. The target current value and the current value signal Iw are compared, and a difference signal corresponding to the difference current value is output.

  The duty determining means 27 determines the duty value of the PWM signal based on the difference signal output from the current value comparing means 26, and outputs a signal corresponding to the determined duty value. That is, the duty determining means 27 determines the duty value based on the target current value and any one selected current value signal. The PWM signal output means 28 outputs a PWM signal having the duty value determined by the duty determination means 27.

  The switch signal output means 29 is based on the energization timing signals (Uh, Vh, Wh, Ul, Vl, Wl) output from the energization timing output means 22 and the PWM signal output from the PWM signal output means 28 from the first. A sixth switch signal (Uhs, Vhs, Whs, Uls, Vls, Wls) is formed, and the formed first to sixth switch signals (Uhs, Vhs, Whs, Uls, Vls, Wls) are formed as a three-phase inverter. Supply to circuit 10. Here, the first switch signal Uhs is supplied to the switch element UH, the second switch signal Vhs is supplied to the switch element VH, the third switch signal Whs is supplied to the switch element WH, and the fourth switch signal Uls is supplied to the switch element UH. On the other hand, the fifth switch signal Vls is supplied to the switch element Vl, and the sixth switch signal Wls is supplied to the switch element Wl.

  The first to sixth switch signals (Uhs, Vhs, Whs, Uls, Vls, and Wls) correspond to the energization timing signals (Uh, Vh, Wh, Ul, Vl, and Wl), and each at an electrical angle of 360 degrees. It becomes an ON section over an electrical angle of 120 degrees. The first to sixth switch signals (Uhs, Vhs, Whs, Uls, Vls, Wls) are always on during the first electrical angle of 60 degrees, and the energization timing signals (Uh, Vh, Wh, Ul, Vl). , Wl), the PWM interval in which the PWM signal output from the PWM signal output means 28 is formed at the electrical angle of 60 degrees in the latter half is formed. Further, the first to sixth switch signals (Uhs, Vhs, Whs, Uls, Vls, Wls) are based on energization timing signals (Uh, Vh, Wh, Ul, Vl, Wl), respectively, in a predetermined order. It becomes an on section.

  In the present embodiment, for example, as shown in FIG. 3, the first switch signal Uhs becomes an on period from time t5 to t7 corresponding to the electrical angle of 120 degrees corresponding to the energization timing signal Uh. The first switch signal Uhs has an electrical angle of 60 degrees in the first half from time t5 to time t6 when the “on switching signal” of the energization switching signal Vl or the “off switching signal” of the energization switching signal Wl is formed. In the latter half electrical angle of 60 degrees from time t6 to time t7, it is a PWM section.

  The first to sixth switch signals (Uhs, Vhs, Whs, Uls, Vls, Wls) are predetermined fifth, third, fourth, second, sixth, first, fifth,. .. Are turned on in the order of switch signals (Vls, Whs, Uls, Vhs, Wls, Uhs, Vls...).

  As described above, in the motor control device 1, the first to sixth switch signals (Uhs, Vhs, Whs, Uls, Vls, Wls) having an on period composed of the first half always-on period and the latter half PWM period. ) Is supplied to the three-phase inverter circuit 10, and the switch elements (UH, VH, WH) of the three-phase inverter circuit 10 are supplied by the first to sixth switch signals (Uhs, Vhs, Whs, Uls, Vls, Wls). , UL, VL, WL) are turned on and off.

  Hereinafter, the effects of the motor control device 1 will be described with reference to FIGS. FIG. 4 shows eleventh to thirteenth switch signals that are “always PWM intervals” over an electrical angle of 120 degrees instead of the first to sixth switch signals (Uhs, Vhs, Whs, Uls, Vls, Wls). (Uhs ′, Vhs ′, Whs ′) and fourteenth to sixteenth switch signals (Uls ′, Vls ′, Wls ′) that become “always-on intervals” over an electrical angle of 120 degrees are represented by a three-phase inverter circuit. The eleventh and twelfth control currents (Iu ′, Iv ′) flowing through the SR motor 1000 when supplied to the motor 10 are shown. The current value signal output to the current value comparison means is Iw from time t1 to t3, Iv from time t3 to t5, and Iu from time t5 to t7.

  As shown in FIG. 4, when the 11th to 16th switch signals (Uhs ′, Vhs ′, Whs ′, Uls ′, Vls ′, Wls ′) are supplied to the three-phase inverter circuit 10, The actual current waveforms of the eleventh and twelfth control currents (Iu ′, Iv ′) flowing are greatly different from the ideal current waveform indicated by the dotted line in FIG. That is, the eleventh control current Iu ′ has an excess current time zone in which the current value exceeds the target current value I0 from time t3 to t4 and the twelfth control current Iv ′ from time t1 to t2. Further, the eleventh control current Iu ′ has a time zone of insufficient attenuation from the time t1 to t2, and the twelfth control current Iv ′ from the time t5 to t6.

  When excessive current flows through the motor control device as described above, the switch elements (UH, VH, WH, UL, VL, WL) used in the motor control device may be damaged. Further, as shown in the figure, the U-phase and V-phase coils (U, V) in the time zone in which the inductance L of the U-phase and V-phase coils (U, V) connected in series decreases from time t1 to t2. ) Is insufficiently attenuated, the braking force acts in a direction opposite to the control rotation direction of the rotor 120. For this reason, the output performance of the SR motor 1000 is lowered.

When the eleventh to sixteenth switch signals (Uhs ′, Vhs ′, Whs ′, Uls ′, Vls ′, Wls ′) are supplied to the three-phase inverter circuit 10 based on FIG. I will explain what happens. As shown in FIG. 4, after the eleventh control current Iu ′ is supplied from the U-phase coil U to the V-phase coil V, the twelfth control current is continuously supplied from the W-phase coil W to the V-phase coil V at time t1. Before and after the time t1 at which Iv ′ is supplied, the switch element VL is turned on by the fifteenth switch signal (Vls ′). Since the switch element WH is driven by PWM, when the switch element WH is OFF, the eleventh control current Iu ′ flowing from the U-phase coil U to the V-phase coil V before time t1 is changed from the switch element VL to the switch element. The electric circuit passing through the UL is recirculated, and the current value is not sufficiently attenuated.

  On the other hand, when the first to sixth switch signals (Uhs, Vhs, Whs, Uls, Vls, Wls) are supplied to the three-phase inverter circuit 10 as shown in FIG. The actual current waveform of the first control current (Iu, Iv) approximates the ideal current waveform indicated by the dotted line in FIG. That is, from time t3 to t4 in the first control current Iu and from time t1 to t2 in the second control current Iv, the current value is suppressed from exceeding the target current value I0, as in other time zones. The control current (Iu, Iv) does not exceed the target current value I0. Further, the current value of the first control current Iu is sufficiently attenuated from time t1 to t2, and the value of the twelfth control current Iv is sufficiently attenuated from time t5 to t6.

  Since the control current (Iu, Iv) does not exceed the target current value I0 as described above, the switch elements (UH, VH, WH, UL, VL, WL) used in the motor control device are damaged. There is nothing to do. Further, as shown in the figure, the U-phase and V-phase coils (U, V) in the time zone in which the inductance L of the U-phase and V-phase coils (U, V) connected in series decreases from time t1 to t2. ) Is sufficiently attenuated, the braking force does not act in the direction opposite to the control rotation direction of the rotor 120. For this reason, the output performance of the SR motor 1000 is improved.

  Based on FIG. 7, it will be described that when the first to sixth switch signals (Uhs, Vhs, Whs, Uls, Vls, Wls) are supplied to the three-phase inverter circuit 10, the control current is sufficiently attenuated. . As shown in FIG. 6, after the first control current Iu is supplied from the U-phase coil U to the V-phase coil V, the second control current Iv is continuously supplied from the W-phase coil W to the V-phase coil V at time t1. , The switch element VL is always turned on by the fifth switch signal Vls before the time t1. After time t1, the switch element WH is always turned on by the third switch element signal Whs, and the switch element VL is PWM-driven by the fifth switch signal Vls.

  Therefore, the first control current Iu flowing from the U-phase coil U to the V-phase coil V before time t1 is the U-phase coil U and V-phase coil in order from the switch element UL when the switch element VL is off. V flows from the electric circuit passing through the switching element VH to the power source BT, and the current value is sufficiently attenuated.

  The present invention is not limited to the above-described embodiment, and includes various modifications made to the above-described embodiment without departing from the spirit of the present invention. For example, in this embodiment, the U-phase, V-phase, and W-phase coils (U, V, W) have a star connection structure, but are not limited to this, and may have a delta connection structure.
