Control and driving circuit diagram of three-phase DC motor in Y connection

Published:2011/9/6 22:52:00 Author:Vicky | Keyword: control and driving circuit, three-phase DC motor, Y connection

In this circuit, the three-phase winding of the motoris in Y connection. If one is conducted by another, when power diode VF1 and VF2 are conducted, the current flows to A phase winding, and then back to the power supply by C phase winging after flowing through VF2. If the torque generated by the current which flows to the windings is positive, then the torque generated by windings is negative. When the motors turnfor60 degrees, VF2 andVF3 are conducted instead of VF1 and VF2. Meanwhile, the current flows to B phase winding from VF3, and then back to the power supply by C phase winding after flowing through VF2.   (View)

Bi-directional speed-adjusting motor driver circuit diagram

Published:2011/9/7 9:27:00 Author:Vicky | Keyword: bi-directional, speed-adjusting, motor driver circuit

Output and level conversion Output signal line is introduced by Port. Pin Port1 is the input end of motor direction signal, pin port2 is the PWN signal input end, and pin port3 is the grounding line. Attention that pin port3 is grounded and connected with a 2kΩ resistance. When the driver panel and monolithic provides power respectively, the resistance can provide the backflow passageway for signal circuit. When the driver and monolithic together use a same group of power, the resistance can prevent high current from flowing to the monolithic mainboard ground wire along the line which will lead to interference. Or, it is equivalent to separate the ground wire of the friver panel and the ground wire of monolithic, and to realize “one-point earth fault”. Capacitance C1 prevents the voltage from going down suddenly which is caused by the sudden start-up of the motor.   (View)

Schematic of lithium battery protection devices is shown in the above picture, which is realized mainly by battery protection control IC , exterior discharging switch M1 and charging switch M2. When P+/P- end is connected with charger, M1 and M2 are all under conducting state when the battery is charged normally; when the control IC detects any abnormality during charging, M2 is then cut off and charging process stops. When P+/P- end is connected with load, M1 and M2 are all under conducting state when the battery is discharging; when the control IC detects any abnormality, M1 is cut off and discharging process stops. In addition, XB4301 cannot be reversely connected. XB4301 is mainly used in MP3 and Bluetooth at present, including partial mobiles, GPS application.   (View)
