Electric hoist motor selection notes
Electric hoist motor selection notes
Electric hoist is the most widely used light lifting equipment, its working characteristics with repeated short-term operation, frequent lifting, reversing and braking, often overload, operating environment for dust and metal dust environment, strong vibration, so in order to meet the needs of electric hoist, as its main power source of the motor should have the following characteristics:
1, the first electric hoist motor should be more than ordinary industrial motor intermittent cycle characteristics, according to the load duration, the number of contacts, the number of lifting as an important parameter selected for the motor.
2, electric hoist motor should have a better lifting torque and overload capacity,
3, electric hoist motor with a smaller rotor inertia, greater rotor diameter to diameter, less line of sight brake.
4, electric hoist on the motor should have the maximum safety speed is several times the rated speed, under normal circumstances is about 2.5 times the synchronous speed.
5, electric hoist motor should be adapted to different operating temperature and humidity, and should be the lowest with two levels of the same insulation level.
