The important component of the stage electric hoist is the motor, which is the core component. In order to extend the service life of the motor, there is a protective device on the motor, which is called a protector.
The traditional stage electric hoist motor protectors use thermal relays, which have low sensitivity, stability, and performance, and the protection of the motor is not very reliable. Due to the increasing demand for motor strength and weight reduction, the demand for motor protectors is also increasing.
A good motor protector may not be multifunctional or particularly advanced. It should meet the needs and have a high cost performance ratio. Choose the type of stage electric hoist motor protector based on the actual situation on site, while considering the installation, adjustment, and simple and convenient use of the protector.
The motor also needs regular maintenance to extend the service life of the stage electric hoist.
