Gantry crane cable reel hysteresis control method and characteristics

Hysteresis type cable reel for the constant torque output, the motor must start synchronization with the host running gear,jib crane and the host is stopped according to the carts glide situation, choose the right reel motor off delay. If you use multiple hysteresis driver must ensure that the motor turning and in conformity with the order requirements. Namely: walking carts, reel motor is energized, regardless of being anti-car or cars, reel motor phase sequence unchanged; carts stop, reel motor off delay.

Three-phase asynchronous motor and hysteresis coupling component cable reel speed control system power. Equipment towards the cable anchor position, the motor is energized to work through the rear drive gear torque amplification winding cable reel rotation.eot crane This process is carried out by the hysteresis drive differential adjustments to ensure the closing process and the carts run the synchronization cable; equipment leaving the cable anchor position, the motor is energized and the phase sequence is unchanged, carts running trailing cable, so that the reel produce greater magnetic hysteresis torque drives, synchronous release of the cable.
