A detailed explanation of the common starting methods for electric motors
The motor should be the most familiar electrical equipment for electrician maintenance technicians. The motor can be started at various times, including direct start, star-delta step-down start, auto-coupling decompression start, soft starter start, inverter start-up Waiting for the way. The following is a detailed explanation of the five main starting methods of the motor.
1. Full pressure direct start
In the case where both full-voltage direct start is allowed in both grid capacity and load, the full-voltage direct start can be considered. The direct start of full pressure has the advantages of convenient operation control, simple maintenance and economical. It is mainly used for starting low-power motors. From the perspective of saving energy, this method is not recommended for motors larger than 11 kW.
2. Auto-decompression start
The multi-tap decompression of the auto transformer can not only meet the needs of different load starting but also obtain a larger starting torque. It is a decompression starting method that is often used to start a large capacity motor. The biggest advantage of an auto-coupling start-up is that the starting torque is large. When the winding tap is at 80%, the starting torque can reach 64% when it is directly started. And the starting torque can be adjusted by tapping. It is still widely used today.
