Description

FEATURES: YZ & YZR series three-phase asynchronous motors are new series products designed in China for hoisters and metallurgical machines. Compared with aeries JZ2 and JZR2, they have increased their efficiency by 1.*8%, output by 9.*5%, and starting torque slightly. The rating class and mounting dimensions comply with the requirements of IEC*2 standard. The rotor of motor of series YZR is of wound type, whereas that of series YZ is of squirrel cage type. These motors are suited for power drive for the hoisters and other similar equipment, short time running duty type S2 or international periodic duty type S3, starting and braking frequently, and the equipment having obvious impact and vibration. OPERATING CONDITIONS: Ambient temperature: **5℃≤0≤*0℃ Altitude: Not exceeding ***0 meters Rated voltage: **0V ±5 Rated frequency: *0Hz Insulation class: Class F / H Duty / Rating: Continuous(S3) Protection type: The main body of the motor IP*4, IP*4 Cooling type: IC**0, IC**1 Connection: Star connection is adopted in stator winding for those motors whose powers are no more than **2KW
