strong electric winch is the most widely used light lifting equipment, its working characteristics, repeatedly short running, frequent lifting, inversion, and braking, overload Strong Electric Winch, often multiple environment much homework dust and metal dust environment, work with a strong shock when, so in order to content with Electric Hoist. As its main source of power of motor should have the following features: 1, the first electric hoist motor should be stronger than ordinary industrial motor has intermittent cycle working characteristic, on the basis of duty cycle Strong Electric Winch, contact number, number of hoisting motor is chosen as an important parameter. 2, there should be a better electric hoist motor starting torque and overload ability, 3, electric hoist motor for a smaller rolling rotor inertia, the bigger the rotor length to diameter ratio Strong Electric Winch, less the line of sight of braking. (4), electric hoist motor should be with a maximum safe speed is several times of rated speed, generally is about 2.5 times that of the synchronous speed. 5, electric hoist motor should be adapted to different working temperature and humidity, and should have two at the lowest level of insulation level.
