Electric Motor 1.YZR series Crane Electric Motor 2. Frame 112 to 400 3. The basic duty is S3-40% 4. Class F and Class H

These series of 3 phase metallurgical industrial and crane electric motor is well suited for short duty cycle, or intermittent periodic duty, and an equipments with frequent starting and braking or are subject to vibration and shock.

 

The standard range of power output and mounting dimensions complies with the reconmmended standard of (IEC72). The relation between range of power output and mounting dimensions is similar to the Japanese standard (JEM1202) and German standard (DIN42681), therefore most of them can be interchanged.

 

The motor can be operated well up to altitude of 1000m.

 

There are 2 classes of insulation F and H. Class F applies to temperature condition not exceeding 40. Class H is suitable for metallurgical industrial sites where ambient temperature is below 60. Both have the same technical data.

 

The motors possess better enclosure, with protection standard of IP44 for normal site condition, and IP54 for metallurgical industrial condition.

 

The YZR series 3 phase induction metallurgical industrial and crane motor with wound rotor is compling with the standard ZBK26008-89. The YZ series 3 phase induction metallurgical industrial and crane motor with squirrel cage rotor compling with the standard ZBK26007-89.

Motors rated voltage and frequency is 380V/50Hz.
