YEZ series three-phase asynchronous motor with electromagnetic brake for construction lifter is specially developed for construction lifter and other construction machinery that use electric drive, meet the national standard GB755-87 <basic technology requirements of rotating motor> and mechanical industry standard JB/T7563-2005 <technical condition requirements of YEZ series electromagnetic braking three-phase asynchronous motor for

crane and metallurgy>, the motor has characteristics of large starting torque, small starting current, high efficiency, low temperature rise, low noise , strong overload capacity, besides, the braking part of the motor using the buffer & delay technology, this makes the starting and braking more stable. With brake clearance automatic tracking compensation function, it eliminates the trouble that the user adjust the friction pair, so the motor has the advantages of simple use, convenient maintenance etc..

Rated frequency 50Hz, rated voltage 380V. Rated frequency can also be made into 60Hz, the according rated voltage is 440V.

Motor cooling method is IC411 (totally enclosed with self-fan).

Motor reference duty: S3-25%.

The motor insulation class is F, the winding temperature rise is 100K.

Shell protect feature of the motor is IP44, the junction box is IP54.
