The motor is the most important part of the lifting chain hoist. It plays an irreplaceable role in the normal operation of the equipment. As the manufacturer of the lifting chain hoist, the selection of the motor is the most prudent part. The motor as the lifting chain hoist should have stronger intermittent working characteristics than the ordinary industrial motor. According to the load continuation rate, the number of contacts and the number of lifting times, it is an important parameter for the motor selection.
The hoisting hoist motor should have better lifting torque and overload capacity; it should have smaller rotor moment of inertia, larger rotor aspect ratio, less line of sight braking; should adapt to different operating temperatures and Humidity, and should have a minimum of 2 levels of insulation.
The maximum safe speed of the motor on the lifting chain hoist should be several times the rated speed. Under normal circumstances, it is about 2.5 times of the synchronous speed. As a user when purchasing a lifting chain hoist, you should also pay attention to the motor condition to ensure that you can choose the product that suits your requirements and quality.
