These series of metallurgical and crane 3-phase motor YZR,YZ with wound and squirrel cage rotor are specially used to drive metallurgical crane and other similar machines with better overload capability and mechanical strength,therefore,it is suitable for short time duty or intermittent period duty and equipments with frequent starting and braking or distinct vitration and impact.
The standard range of power output and mounting dimensions are in comply with the reconmended standard of IEC 72,the relation between range of power output and mounting dimensions are similar to standard JEM1202 and West Germany standard DIN42681,so that most of them can be interchanged.
The motor can work well when the altitude does not exceed 1000m.
There are two classes of F and H insulation,Class F is applicalbe to suit temperature which cool air does not exceed 40 under normal condition,Class H is suitable for metallurgical sites when ambient temperature no exceeding 60 both motors have same data.
The motors possess better enclosure,degree of protection IP44 for normal site condition,and IP54 for metallurgical condition.
Motor's rated voltage and frequency is 380V,50HZ.

1.Short-time duty type (S2)
Operation of constant load during a given time, less than that required to reach thermal equilibrium, followed by a rest and de-energized period of sufficient duration to re-establish machine temperature within 2 deg K of the coolant.

2. Intermittent periodic duty type (S3)
A sequence of identical duty cycles, each including a period of operation at constant load and a rest and de-energized period but the operation period are so short that it is not sufficient for the machine to reach thermal equilibrium In this duty type, the cycle is such that the starting current does not significantly affect the temperature rise.

3. Intermittent periodic duty type with starting (S4)
A sequence of identical duty cycles, each including a significant period of starting, a period of operation of constant load and a rest and de-energized period, but the operation period are so short that it is not sufficient for the machine to reach thermal equilibrium.

4. Intermittent periodic duty type with electric braking (S5)
A sequence of identical duty cycles, each consisting of a period of starting, a period of operation at constant load and a rest and de-energized period, but the operation period are so short that it is not sufficient for the machine to reach thermal equilibrium.
