Therefore, when a motor drive module is used in an operation mode without a micro control signal, since there is no micro control device to provide a PWM control signal relationship, this type of motor drive module cannot generate a control motor via the PW signal. The motor drive module of this type can only drive the motor to achieve heat dissipation at a fixed speed. [0003] In order to enable the motor drive module used in the micro-control mode to generate the required motor speed according to the heat dissipation requirement of the product, there are several methods for adjusting the motor speed. The first one is to change the motor. The load is shown in Figure 1; the second is the mode of changing the operating voltage, as shown in Figure 1β.

If there is no force (4) relationship, the guide module will continue to be provided according to the setting. Voltage After the motor consumes power, the inch can cause the motor to wrap around the motor. In addition to the addition of the invention, in order to solve the aforementioned problems, the main purpose of the present invention to externally connect the motor drive module is to expose a road design. Therefore, the motor drive wedge group can be used for the function of the external power supply, so that the drive module can generate different PWM output signals without micro-controls, and the motor can improve the electric waste according to different products. The application of the motor winding limit motor speed 'except for the series connection of a resistor, so the Dingma is not required to work at the load end again.

使得比較器11第一輸入端維持在VRS的電位，也使得比較 器11的輸出端能夠持續地輸出一個PWM輸出電壓訊號Cout 至輸出單元200，以驅動馬達300轉動。 [0023] 如果馬達停止運轉時；例如：當馬達驅動裝置10所提供 的VRS的電位無法克服馬達300起動的力矩（torque ); 或是馬達300在正常起動後，因外力造成馬達300被鎖住 而停止轉動等；由於霍爾元件310無法正常輸出霍爾電壓 波形訊號，使得脈波產生器18也無法正常輸出脈波訊號 ，因此，由振盪器16所形成的計數器之抑制訊號便會消 失，此時計數器會開始計數，如第8圖中的mot or-1 ock 區域。一旦當計數器計數的時間超過第一預設的時間後 :例如：計數的時間超過0. 5秒；此時代表馬達己經停轉 動，而閂鎖強制起動器19會送出一個RD高電位信號至開 關swl的輸入端；例如：將RD訊號送到一NM0S的閘極端 099145418 表單編號A0101 第14頁/共26頁 0992078272-0 201228211 ，使得NMOS被導通；透過開關swi的鐾 … 心& 4 4 通來將VRS電壓會 被降至接地點（即GND點）的低電位（態；很明顯地，這 時間候的比較器U不會輸出剛輸出電壓訊號㈣至輸^ 早元2 0 0。 [0024] Ο 當閃鎖強制起動器19送出一娜高電位信號至開關^的 輸入端的同時’由振盡器16所形成的計數器仍然繼續計 數，當計數器計數的時間超過第二預設的時間後；例如 :將第二預設的時間設定為第一預設的時間的5-10倍的 時間問鎖強制起動器19送出一個拙低電位信號至開關 Swl的輸入端’使得開關swl被關初（off )，如第8圖中 的l〇ck-release區域。此時，比較器一輸入端會恢 復至VRS的電位’也使得比較器η的輸出端能夠持續地輸 出一個PWM輸出電壓訊號c〇ut至輸出單元200，以驅動馬 達300轉動。在此要強調，第二預設的肆間的設定之一目 的是要確認馬達已經停止後，再以外部電壓調整電路2〇 所提供之VRS電壓來重新驅動馬達3〇〇轉動。 Ο [0025] 再接著，本發明提供男一可以調整閂鎖強制起動裝置中 的起動電壓電路。再如第6圖所示，與馬達驅動裝置1〇連 接的外部電壓調整電路2〇，其係由連接的電阻R1、R2和 電容C1所組成的RC充電電路，其中電容C1可以由多個電 容所組’而此RC充電電路可以經由對電阻或電容的大小 來決定VRS電壓的充電時間常數（RC time constant) 。當馬達300被鎖住時，閂鎖強制起動器19會送出一個RD 高電位信號至開關SW1的輸入端，使得開關SW1的導通來 將VRS電壓會被降至接地點（即GND點）的低電位狀態； 099145418 表單編號A0101 第15頁/共26頁 0992078272-0 201228211 此時，在外部電壓調整電路20與比較器11第一輸入端之 間形成一個放電迴路，使得電容C1會放電至接地電位。 當閂鎖強制起動器1 9送出一個R D低電位信號至開關s w 1的 輸入端，使得開關swl被關閉（off )，此時，比較器11 第一輸入端會重新開始進行充電至VRS的電位。 [0026] 當外部電壓調整電路20所組成的RC充電電路之充電時間 常數太小時，RC充電電路會非常快就充電至VRS電壓，可 能會造成馬達30 0被閂鎖強制起動器19重新起動時，產生 振動（vibration)或是澡音（noise);而此振動或是 噪音對於一些較精密的裝置而言，是需要避免的；例如 :藍光DVD等；因此，可以選擇外部電壓調整電路20的電 阻Rl、R2和C2所組成的RC充電電路，使其具有較長的 VRS電壓的充電時間常數，此時，即可以降低馬達300被 重新驅動時，所產生的振動或是噪音。很明顯地，本發 明之可調整輸出PWM控制訊號的馬達驅動模組10，可以依 不同的應用需求來調整其充電的時間常數。當VRS充電到 所設定值之後就會維持一定，以使馬達300被驅動並達到 先前設定的轉速值，直到下次馬達再被鎖住時，才會誰 重覆以上動作，請參考第9圖之PWM控制訊號與充電電壓 波形之示意圖。 [0027] 以上針對本發明較佳實施例之說明係為闡明之目的，而 無意限定本發明之精確應用形式，由以上之教導或由本 發明的實施例學習而作某種程度修改是可能的。因此， 本發明的技術思想將由以下的申請專利範圍及其均等來 決定之。 099145418 表單編號A0101 第16頁/共26頁 0992078272-0 201228211 【圖式簡單說明】 [0028] 第1 A圖係一種在習知技術中改變馬達負載的馬達驅動裝 置示意圖； [0029] 第1B圖係一種在習知技術中改變改變工作電壓的馬達驅 動裝置示意圖； [0030] 第2A及2B圖係本發明之馬達驅動裝置以及電壓位準調 整之示意圖； [0031] 第3圖係本發明之可調整輸出PWM控制訊號的馬達驅動模 0 組之功能方塊示意圖； [0032] 第4圖係本發明之可調整輸出PWM控制訊號的馬達驅動模 組之一實施例之示意圖； [0033] 第5圖係本發明之馬達驅動裝置之輸出訊號示意圖；及 [0034] 第6圖係本發明之具有閂鎖強制起動裝置之馬達驅動系 統及其控制單相馬達之示意圖； [0035] ❹ 第7圖係本發明之閂鎖強制起動裝置之功能方塊示意圖 9 [0036] 第8圖係本發明之相應閂鎖強制起動裝置之訊號示意圖 〇 [0037] 第9圖係本發明之PWM控制訊號與充電電壓波形之示意圖 〇 [0038] 【主要元件符號說明】 10馬達驅動裝置 099145418 表單編號A0101 第17頁/共26頁 0992078272-0 201228211 [0039] 11 比較器 [0040] 13 三角波產生器 [0041] 15 PWM控制器 [0042] 16 振盪器 [0043] 17 霍爾電壓 [0044] 18 脈波產生器 [0045] 19 閂鎖強制起動器 [0046] 20 外部電壓調整電路 [0047] 30 外接頻率調整電路 [0048] 200 輸出單元 [0049] 21 0/220輸出電路 [0050] 300 馬達 [0051] 310 霍爾元件 [0052] swl 開關 099145418 表單編號A0101 第18頁/共26頁 0992078272-0[0017] When the resistance of the applied circuit 20 to the resistance value of R1/R2 and the Hall voltage connected to the resistor R1 have been designed and determined, the VRS voltage level of the first input terminal of the comparator 11 can be determined; When the capacitor Cv of the external frequency adjusting circuit 30 has also been designed and determined, the triangular wave generator 13 generates a triangular wave (ie, CPWM signal) of a specific frequency according to the capacitance value of the capacitor ^, and is controlled by the comparator 11. The second input is wheeled in. Therefore, the comparator 11' in the motor driving device 10 of the present invention can pass the VRS voltage level input from the first terminal and the binary wave generator 13 generates 099145418 Form No. A0101 Page 10 of 26 pages 0992〇78272- The triangle wave of i 201228211 is cut to generate a PWM signal and output by the output of the comparator 11, as shown in Fig. 5; for example, when the triangular wave of a specific frequency is determined, it can be performed by the VRS voltage level and the triangular wave. Cutting, the closer the VRS voltage level is to the high level, the smaller the DUTY CYCLE of the pWM signal it cuts. The closer the VRS voltage level is to the lower level, the larger the DUTY CYCLE of the PWM signal it cuts. After the PWM signal cut out is subjected to the Leve shift by the PWM controller 15, a PWM control signal for controlling the motor speed can be output. Obviously, a specific PWM signal can be generated after the resistance value of the applied voltage adjusting circuit 20 and the external frequency adjusting circuit 3 are designed by the heat dissipation requirement of the product. Therefore, after the design of the external voltage adjusting circuit 20 and the external frequency adjusting circuit 30, the motor driving device 10 can also adjust the output PWM of the motor driving device 1 without the micro control unit providing the PW Μ control signal. Control signals to meet the cooling needs of each product. Similarly, it should be emphasized here that the PWM controller 15' in this embodiment has its main purpose of performing a Leve shift shift on the pwm signal outputted by the comparator 11 to respond to different voltage systems; for example, converting a 3V signal into 5V or 12V output; therefore, the PWM controller 15 can be configured as needed. [0018] Referring first to Figure 6, there is shown a schematic diagram of a motor drive system having a latch-activated starting device and a single-phase motor thereof. As shown in FIG. 6, the motor drive system 1 includes a motor drive unit 10 and a single-phase motor 300 output unit 200. The motor drive unit 10 includes a comparator 11, a triangular wave generator 13, an applied voltage adjustment circuit 20, and an external frequency. The adjustment circuit 30 is composed of. When the PWM control signal outputted by the motor driving device 10 is sent to 099145418, the form number AOUn is 11th/26 pages 0992078272-0 201228211 to the wheeling unit 200, the driving voltage formed by the duty CYCLE which is rotated by the PWM control mirror The output circuit and the output circuit 22 are controlled to supply current to the coil 'on the motor 3 (10) (for example, a single-phase motor) to drive the motor 300 to rotate. Next, the Hall element 310 on the motor 3 turns the commutation signal of the motor 300 to the wheel unit 2 to determine whether the motor 3GG is continuously rotating. When the motor has been continuously rotated, the pWM control signal output from the motor driving device 1 is continuously sent to the output unit 200. It is to be noted that the PWM control signal provided by the motor driving device 1G in the motor drive system 1 is the same as that of the embodiment of FIG. 4 and will not be described herein. [0020] Furthermore, the simple control signal that is rotated by the motor drive device 1 of the present invention can be used to control a three-phase motor in addition to driving a single-phase motor 3〇〇; When the motor drive unit 1 is used to control a three-phase motor, the control signal output from the motor drive split 1 同样 can also be sent to the U/V/W coil on the three-phase motor (not shown). It can be used to drive the rotation of the three-phase motor; the structure of the island motor is the same as the conventional technology, so it will not be described again. .> ·:. : :·: Since the motor drive module of the present invention is used in a micro-control device, it is not possible to determine whether the motor has been started or not, and can only drive the motor with the set just control signal. The value of the starting torque (t〇rque) is relatively large when the motor is just started. If the motor is set to a low speed, the starting torque (t〇rque) may not be enough. As a result, the motor may not be able to run at the beginning of the start. Secondly, when the motor is affected by external force or irresistible to cause the motor to stop, the motor will not be able to start the torque relationship due to the 099145418 form number A0101 page 12/26 pages 0992078272-0 201228211 Start again. Therefore, if ‘, ,,. The starter motor & drive module still continues to increase the Wei power when the motor is just controlled, and may also cause the horse T° to solve the problem that the motor cannot be started. The present invention further provides a motor drive. A quick start circuit is configured in the module. [0021] ο ο : The motor drive module of the present invention is used in the micro-control mode, in addition to the function of adjusting the output pwM control signal according to product requirements, the present invention can further advance into the motor drive module. Configuration—The circuit for forcibly starting the flash lock, please refer to FIG. 6 . As described above, the motor drive module of the present invention is driven by a motor L... a circuit 2 for external voltage adjustment formed in the motor drive unit U. (ie, the resistor is hidden) and: a frequency adjustment circuit 30; wherein the motor medium device (4) includes a comparator 11' whose first input terminal is connected in series with the resistor _/R2, and the second input terminal thereof The triangular wave generator 13 is connected. After comparing the two input voltages through the comparator 11, the comparator u outputs a PWM output voltage signal Cout from the output terminal to the output unit (10) to drive the motor 3〇〇 to rotate. Then, the flash lock forced starting device of the present invention comprises a comparator 1 whose first input terminal is connected to the switch sw1, and the second wheel end of which is connected to the first and second wave house 13 for printing 1丨5$ The starter 19 has its first input connected to a pulse generator 18, its other input connected to an oscillator 16, and its output connected to the switch, as shown in Fig. 6, please Referring to Fig. 7 and Fig. 8 'the seventh figure is a functional block diagram of the forced start device; and Fig. 8 is a schematic diagram of the signal of the corresponding forced start device. First, as shown in Figure 7, please be the motor class 099145418 Form No. A0101 Page 13 / Total 26 Page 0992078272-0 [0022] 201228211 During normal rotation, the Hall element (HALL SENSOR) 310 will rotate the motor 300 The normal output of the commutation voltage waveform signal (also referred to as Hall voltage) causes the pulse generator 18 to generate a pulse signal by the Hall voltage signal, thereby suppressing (RESET) the oscillator 16 by the pulse signal. The resulting counter counts; wherein the pulse generator 18 generates a pulse signal at the location where the Hall voltage signal is commutated, as shown in FIG. In other words, when the motor 300 is in normal rotation, the counter count formed by the oscillator 16 is suppressed. At this time, the latch forced starter 19 outputs a low voltage signal of RD, and therefore, with the comparator 11 The switch sw1 connected to an input terminal is also not turned on; for example, the RD signal is sent to the gate terminal of the NM0S formed by a semiconductor component, so that the NM0S is turned off; so that the first input of the comparator 11 is maintained at the VRS. The potential also enables the output of the comparator 11 to continuously output a PWM output voltage signal Cout to the output unit 200 to drive the motor 300 to rotate. [0023] If the motor stops running; for example, when the potential of the VRS provided by the motor driving device 10 cannot overcome the torque of the motor 300; or the motor 300 is locked after the normal starting, the motor 300 is locked due to an external force. The rotation of the Hall element 310 does not normally output the Hall voltage waveform signal, so that the pulse wave generator 18 cannot output the pulse wave signal normally. Therefore, the suppression signal of the counter formed by the oscillator 16 disappears. At this point the counter will start counting, as in the mot or-1 ock area in Figure 8. Once the counter counts for more than the first preset time: for example, the counted time exceeds 0.5 seconds; at this time, the representative motor has stopped rotating, and the latch forced starter 19 sends an RD high potential signal to The input of the switch swl; for example, the RD signal is sent to the gate terminal of a NM0S 099145418 Form No. A0101 Page 14 / 26 pages 0992078272-0 201228211, so that the NMOS is turned on; through the switch swi... Heart & 4 4 The VSD voltage is reduced to the low point of the grounding point (ie, the GND point). Obviously, the comparator U at this time does not output the just output voltage signal (4) to the input 2 early 0. [0024] Ο When the flash lock forced starter 19 sends a high-potential signal to the input of the switch ^ while the counter formed by the vibrator 16 continues to count, when the counter counts for more than the second preset time Afterwards; for example, setting the second preset time to 5-10 times the time of the first preset time, the lock starter 19 sends a low potential signal to the input end of the switch Sw1 to make the switch swl off. Initial (off), such as The l〇ck-release area in Fig. 8. At this time, the comparator input will return to the potential of VRS', so that the output of the comparator n can continuously output a PWM output voltage signal c〇ut to the output unit 200. It is emphasized that the driving motor 300 rotates. It is emphasized here that one of the second preset setting of the turn is to confirm that the motor has stopped, and then re-drive the motor 3 with the VRS voltage supplied from the external voltage adjusting circuit 2〇. 〇〇Rotating. [0025] Next, the present invention provides a starting voltage circuit that can be adjusted by the male one in the latching forced starting device. Further, as shown in FIG. 6, the external voltage adjusting circuit 2 connected to the motor driving device 1A 〇, which is an RC charging circuit composed of connected resistors R1, R2 and a capacitor C1, wherein the capacitor C1 can be composed of a plurality of capacitors, and the RC charging circuit can determine the VRS voltage by the magnitude of the resistor or capacitor. RC time constant. When the motor 300 is locked, the latch forced starter 19 will send an RD high potential signal to the input of the switch SW1, so that the switch SW1 is turned on to turn the VRS The voltage will be reduced to the low potential state of the ground point (ie, GND point); 099145418 Form No. A0101 Page 15 of 26 0992078272-0 201228211 At this time, the external voltage adjustment circuit 20 and the first input of the comparator 11 A discharge loop is formed such that the capacitor C1 is discharged to the ground potential. When the latches force the starter 19 to send an RD low potential signal to the input of the switch sw1, the switch swl is turned off (off), at this time, the comparison The first input of the device 11 restarts the charging to the potential of the VRS. When the charging time constant of the RC charging circuit composed of the external voltage adjusting circuit 20 is too small, the RC charging circuit charges to the VRS voltage very quickly, possibly causing the motor 30 0 to be latched to force the starter 19 to restart. , generating vibration or noise; and this vibration or noise is necessary for some more sophisticated devices; for example, Blu-ray DVD, etc.; therefore, the external voltage adjustment circuit 20 can be selected. The RC charging circuit composed of the resistors R1, R2 and C2 has a charging time constant of a long VRS voltage, and at this time, the vibration or noise generated when the motor 300 is re-driven can be reduced. Obviously, the motor drive module 10 of the present invention, which can adjust the output PWM control signal, can adjust the time constant of charging according to different application requirements. When the VRS is charged to the set value, it will remain constant, so that the motor 300 is driven and reaches the previously set speed value until the next time the motor is locked again, who will repeat the above action, please refer to Figure 9.
