Is the high-speed and low-speed power supply of the variable frequency electric hoist the same?

The variable frequency electric hoist is an electric hoist with two frequencies that can be used, but the two frequencies are one high speed and one low speed. Is the power supply the same when using the two speeds? Let's take a look together.

 

The frequency conversion electric hoist is often used in daily work. Because of the unique two speeds, it is more expensive in price. It needs to be adjusted to high-speed use when it is used at high speed, and it needs to be used in detail. When processing, it is adjusted to a low-speed state, and there is no need to cut off the power in the middle. This avoids reducing the damage to the motor caused by the second start during the use process, so that the operation is more stable and the impact is reduced. If it is used in the state, the electricity used is the same. It should be because a frequency converter is added to the electric hoist. The motor does not change, so the power supply is the same.

 

In the no-load state, we can increase the speed to 1.5 times the rated speed and switch between the rated speeds to increase the running speed under no-load, thereby improving work efficiency.
