■ Product's Introduction

     YZTD series Pole-changing multi-speed three-phase asynchronous motor is specially designed for tower crane and other construction machinery with electric drive. YZTD type has the characteristics of big speed ratio, small starting current, large starting torque, strong overload capacity and so on. As the motor is a squirrel cage rotor motor uses advanced technology of speed regulating by far pole change, there is no brush device which is easy to be worn and torn, also no additional speed-adjusting device. So it is easy to be handled and maintained.

Cooling method: ICO411 (totally enclosed with self-fan).
Working methods: S3-40% for high and medium speed, S3-25% for low speed .
Shell protect:IP44, the terminal box is IP54.
insulation class: F
winding temperature rise is100K.
