YZTD2 series multi-speed three-phase asynchronous motor for tower crane hoisting
YZTD2 series multi-speed three-phase asynchronous motor is a cage-type rotor variable-pole multi-speed three-phase asynchronous motor specially developed for the electric power transmission of tower cranes and other construction machinery, which adopts advanced far-pole ratio variable-pole speed regulation technology, so that the motor has the characteristics of large speed regulation ratio, small starting current, high starting torque and strong overload capacity. Since the motor is a squirrel cage rotor motor, there is no brush device which is easy to wear and tear, and there is no need for additional speed control device, therefore, it is simple to use and easy to maintain, and it is widely used in the hoisting mechanism of medium and small tower cranes.
