The electric chain hoist which is most widely used light lifting equipment has the characteristics of repeated short run, frequent lifting, braking and reverse current, overload, multi metal dust and dust operating environment, strong vibration. Therefore, in order to meet the needs of electric hoist, as its main power source of the crane motor should have the following characteristics:
1. First, the electric hoist motor should have characteristics of stronger intermittent cycle working than the ordinary industrial motor, according to the load duration, the number of contacts and the number of times as an important parameter of motor selection.
2. Electric crane duty motor should have better lifting torque and overload capacity.
3. Electric hoist motor due to smaller rotor inertia, greater rotor length diameter ratio, less sight braking.
4. Electric hoist motor should have the maximum safe speed which is several times the rated speed, generally is about 2.5 times the synchronous speed.
5. Electric hoist motor should be adapted to different operating temperature and humidity, and should have 2 grade insulation at least.

If the supply voltage exceeds ± 10% compare to the standard voltage, operation may cause damage to the motor under this abnormal voltage. Thus operator have to confirm whether the power supply voltage within the operating range of the standard firstly be
》MOREFor many people, the electric hoist is an unfamiliar term, and many people do not understand its use characteristics, but as practical lifting equipment, it has applications in many work fields and is loved by people. For this device, I believe that many
