Variable-frequency Drive

Variable-frequency Drive, VFD, is used to control AC crane motor by variable-frequency technology and microelectronic technology to control the power control equipment of AC crane motor through changing the motor-working power frequency. Crane Variable-frequency Drive helps the motor realize soft-start. 

1. Application: Variable-frequency Drive for Control AC motor

2. Utilizing variable-frequency technology and microelectronic technology. That makes the Variable-frequency Drive able to control the power control equipment of AC motor through changing the motor-working power frequency.

3. Energy saving and operation accuracy improving.

4. Overcurrent, overvoltage and overload protection.

5.  It helps the motor realize soft-start.
