A stator of a yoke winding single-phase alternating current switch reluctance motor consists of a stator core and an armature winding. The single-phase alternating current switch reluctance motor can be formed by the salient pole rotor, the supporting part, the machine shell, the control circuit and other parts. Is characterized in that: the armature winding is wound around the yoke by adopting an electric wire to form a yoke winding, single-phase alternating current is introduced into the yoke winding according to a yoke single-phase method to form yoke magnetic flux, alternating tooth magnetic poles are formed, a rotary switch reluctance magnetic field is formed, and the salient pole rotor can be driven.

The stator core is manufactured by adopting mature technology and adopting high magnetic flux materials, such as silicon steel, laminated silicon steel and the like. The stator core is arranged according to the requirement, so that each tooth part is uniformly arranged inwards towards the rotor along the circumferential direction, the yoke part is parallel to the movement direction of the rotor, and the yoke part is connected with each tooth part to form the stator core. The phase number of the stator armature winding is set to be P, P is a natural number not smaller than 3, the stator core is provided with 2X Q X P tooth parts and 2X Q X P section yoke parts, Q is the stator pole pair number, and Q is a natural number. The clockwise direction of the stator core is the front direction and the advancing direction, and the anticlockwise direction is the rear direction and the retreating direction. The stator armature winding phase number is the number of armature winding groups through which different currents flow.

The armature winding is an electric wire structure which is electrified with single-phase alternating current to form yoke magnetic flux, form alternating tooth magnetic poles and form a rotary switch reluctance magnetic field, and comprises P-phase armature windings, wherein different currents flow in each phase of armature windings. Each phase of armature winding is wound around the yoke part of the stator core by adopting an electric wire to form a yoke winding, and the yoke windings are arranged in segments along the yoke part according to the phase sequence numbers. The yoke winding arrangement rule is: an armature winding of P phases, each phase armature winding comprising 2*Q sections of yoke windings; selecting a tooth part on a stator core as a first base electrode, wherein the P-th tooth part in front is a first image pole, the 2*P-th tooth part in front is a second base electrode, the 3*P-th tooth part in front is a second image pole, and the like until the Q-th base electrode and the Q-th image pole; p-section positive yoke windings of the P phase are sequentially arranged in front of each base electrode according to the phase sequence numbers, P-section negative yoke windings of the P phase are sequentially arranged in front of each image electrode according to the phase sequence numbers, and 2X Q X P-section yoke windings are arranged. The wire and the number of turns of each yoke winding are the same. The connection modes of the yoke windings in each phase, including series connection, parallel connection, mixed connection and the like, all adopt mature technologies of the motor industry. The positive and negative of each section of yoke winding are determined according to a yoke orientation method, and the yoke orientation method comprises the following steps: a section of the stator core is selected parallel to the moving direction of the rotor, and the section is clockwise in the section view, namely, the section of the yoke magnetic flux is positive yoke magnetic flux when the N pole direction of the yoke magnetic flux is clockwise, and the section of the yoke magnetic flux is negative yoke magnetic flux when the N pole direction of the yoke magnetic flux is anticlockwise. According to the right-hand spiral rule, the yoke windings forming positive yoke magnetic flux are positive yoke windings, the yoke windings forming negative yoke magnetic flux are negative yoke windings when positive current is introduced, the yoke windings forming positive yoke magnetic flux are negative yoke windings when negative current is introduced, and the yoke windings forming negative yoke magnetic flux are positive yoke windings when negative current is introduced. After the single-phase alternating current is fed into each section of yoke winding, alternating yoke magnetic flux is formed. At the same time point, adjacent same-direction yoke magnetic fluxes are connected in series to form a group of yoke magnetic fluxes; the magnetic fluxes of the anisotropic yoke part are mutually concentrated, namely N ends are concentrated, and S ends are concentrated; the teeth collected in the nearest teeth form teeth magnetic poles called teeth poles and face poles, the time points are changed continuously, and the teeth magnetic poles of the teeth poles and the face poles form alternating magnetic poles, namely the magnetic poles of the switched reluctance magnetic field. The alternating magnetic pole of each step of the yoke single-phase method is stabilized at the tooth pole and the face pole of the step, the tooth pole and the face pole position of the next step are determined by the next step of the yoke single-phase method, the rotating direction and the rotating stepping distance of the alternating magnetic pole are formed, the tooth pole and the face pole position advance or retreat along with the change of each step of the single-phase alternating current, a rotating switch reluctance magnetic field is formed, and the rotating frequency of the switch reluctance magnetic field is smaller than the frequency of the single-phase alternating current. * Is the multiplication number,/is the divisor, + is the positive number, the plus number, -is the negative number, the minus number. The phase sequence numbering of the armature windings is a mature technique, usually expressed in lower case alphabetical order.

The armature winding is electrified with single-phase alternating current according to a yoke single-phase method, and each electrified period comprises 2*P steps, namely 2*P equal step length times. The current fed in each step is related to the relative positions of the stator and the rotor, the starting and ending time of each step is selected, the on and off time of single-phase alternating current is selected, and the phase angle of each step is selected by adopting a mature technology. The mature technique involves providing sensors in the motor to obtain stator and rotor position signals for each step, which are provided to a control circuit to control the current supplied to the armature windings of each phase for each step. And after the rotor rotates for a stepping distance, starting to feed current in the next step. The motor start-up may start from any one step and does not have to start from the first step. The yoke single-phase method comprises a No. 1 forward method, a No. 1 reverse method, a No. 2 forward method, a No. 2 reverse method, and the like until a (P-1)/2 forward method and a (P-1)/2 reverse method are adopted, wherein the total is 2 times ((P-1)/2) methods for introducing single-phase alternating current to form a rotary switch reluctance magnetic field, and the value of (P-1)/2 is an integer. The following method 1 is: step 1, each base electrode is taken as the tooth pole, each image electrode is taken as the tooth pole, the P-phase yoke winding is fed with single-phase alternating current, the current rule is that positive yoke windings in P-section yoke windings in front of each tooth pole circulate +A-phase alternating current, negative yoke windings in P-section yoke windings in front of each tooth pole circulate-A-phase alternating current, negative yoke windings circulate +A-phase alternating current, and then each step (until 2*P steps) is carried out, the first tooth part in front of each tooth pole is taken as the tooth pole, and the P-phase yoke windings are fed with single-phase alternating current, so the current rule is unchanged; the stepping distance of the switch reluctance magnetic field of each step is one pole center distance; step (2×p+1) is the same as step 1, and the next power-on cycle is started. The inverse method 1 is: step 1 and step 1 of the 1-step sequential method are carried out, each step (until step 2*P) is carried out, the first tooth part behind each tooth pole of the previous step is used as the tooth pole of the previous step, the first tooth part behind each face pole of the previous step is used as the face pole of the previous step, the P-phase yoke winding is fed with single-phase alternating current, and the current rule is unchanged; the stepping distance of the switch reluctance magnetic field of each step is one pole center distance backward; step (2×p+1) is the same as step 1, and the next power-on cycle is started. The No. 2 sequential method is as follows: step 1 and step 1 of the 1-step sequential method, every step (until step 2*P) is followed, the second tooth part in front of each tooth pole of the previous step is used as the tooth pole of the step, the second tooth part in front of each face pole of the previous step is used as the face pole of the step, the P-phase yoke winding is fed with single-phase alternating current, and the current rule is unchanged; the stepping distance of the switch reluctance magnetic field of each step is two pole center distances; step (2×p+1) is the same as step 1, and the next power-on cycle is started. The inverse method No. 2 is: step 1 and step 1 of the 1-step sequential method are carried out, each step (until step 2*P) is carried out, the second tooth part behind each tooth pole of the previous step is used as a tooth pole of the previous step, the second tooth part behind each face pole of the previous step is used as a face pole of the previous step, the P-phase yoke winding is fed with single-phase alternating current, and the current rule is unchanged; the stepping distance of the switch reluctance magnetic field of each step is two pole core distances which are backward; step (2×p+1) is the same as step 1, and the next power-on cycle is started. The following m-numbered forward method and m-numbered reverse method are analogized, and each step of the method is divided into m pole core distances; and the steps are carried out until the (P-1)/2 forward method and the (P-1)/2 reverse method are carried out, wherein the step-by-step distance is (P-1)/2 polar center distances, and the value of (P-1)/2 is an integer. In each step of each yoke single-phase method, the current rule is unchanged, but the specific current flowing into each section of yoke winding in each step is different. The core of each step of the yoke single-phase method is that the yoke magnetic flux formed by each section of yoke winding is gathered on the tooth pole and the face pole by the current fed in each step to form a switched reluctance magnetic field with correct stepping distance, and the rotating switched reluctance magnetic fields are formed by the successive steps. The step distance of the switched reluctance magnetic field is the number of pole pitches of the tooth pole and the face pole of the next step compared with the last step.

As described above, each step of the m-ary method rotates the rotary switched reluctance magnetic field clockwise by m pole pitches at the m-ary rotational speed, and each step of the m-ary method rotates the rotary switched reluctance magnetic field counterclockwise by m pole pitches at the m-ary rotational speed, where m is a natural number and m is a value equal to (P-1)/2 at maximum, taking an integer. The pole pitch is the arc between the top centers of two adjacent stator teeth. Each step of the switched reluctance magnetic field rotates by m pole center distances, namely, each step of the switched reluctance magnetic field is m pole center distances. Under the condition that each step is the same for a long time, one of the forward method and the reverse method is adopted to form a rotary switch reluctance magnetic field with Q pole pairs and one of various speeds, and the salient pole rotor can be driven to rotate at a certain rated rotation speed. See in particular the examples.

In the yoke winding arrangement rule, each section of yoke winding of any phase is changed into a yoke winding with opposite directions; in each step of each energizing mode of the yoke single-phase method, the original single-phase alternating current corresponding to the phase is changed into single-phase alternating current with 180 degrees of electric phase difference, so that the invention is unchanged. In each energizing mode of the yoke single-phase method, the original single-phase alternating current flowing through each section of yoke winding is changed into single-phase alternating current with 180 degrees of electric phase difference, so that the invention is unchanged.
