Big Torque Motor factory,transformer-motor group start: transformer-motor group power supply and starting mode is another form of full pressure start.When the transformer-motor group is used for power supply and start, the 10kv bus has only one motor, and the voltage drop of the superior bus (35kv and 110kv) is small, so it will not affect the normal operation of other electrical equipment.This power supply and starting mode is simple wiring, reliable operation, economic, small maintenance workload, large starting torque, short starting time, mostly used for capacity motors below 10mw. Two, Reactor start (capacitor start): reactor start refers to the reactor and the motor stator winding in series, to limit the starting current of the motor, motor start after resection, suitable for 6kv or 10kv motor.After the stator string reactor, the starting current of the motor will be reduced in proportion, therefore, the resistance value of the reactor must be selected according to the resistance torque of the motor starts, the motor when the starting torque is greater than the resistance torque will start smoothly.Sometimes the starting conditions are improved by adding reactive capacitors.The advantages of this starting mode is relatively stable, simple wiring, less investment, but the starting current is large, small starting torque, less practical application.
