What is variable frequency electric hoist?
Variable frequency electric hoist is to use frequency converter to change the power supply frequency to control the motor speed.
Frequency conversion electric hoist has the following characteristics:
1. It can reduce the start, stop the impact because the electric hoist has the performance of smooth operation, so can reduce the start, stop the impact, especially for the installation of precision mold is not allowed to have vibration in the working environment.
2. The lifting speed can be set according to the demand. The lifting speed can be set between the rated speed of 1/10 and the rated speed to select the most suitable operation speed.
3. It can improve the working efficiency under no load, can set the lifting speed between the rated speed to 1.5 times the rated speed, improve the operating speed under no load, to improve the working efficiency.
4. It is convenient to set the running speed of the car. The frequency conversion control of the running motor can be carried out through the frequency converter.
