Product Description

YZR YZRE YZRW YZRD series Metallurgical and crane wound rotor slip ring electric ac motor
 Product Description
YZR YZ Series electric ac motor for crane and metallurgical uses, featured with large overload capacity
and adequate mechanical strength, is specially suitable for driving various types of crane and metallurgical machine or other similar equipment.
YZR series electric ac motor is of wound rotor slip ring type, while YZ series electric ac motor is of squirrel cage type.

1. Duty type: S2,S3,S4,S5,S6,S7,S8 and S9. The basic duty type is S340% (duty type is S3, cyclic duration factor is 40%, each cyclic is 10min). The following duty types are most useful to these series motors.
2. Cooling method: IC411, IC410
3. Protection rating: IP55, IP54, IP44
4. Mounting: B3, B5
5. Insulation class: F,H
6. Ambient temperature: -10oC~+60oC, Max. Altitude: 1000m
7. Rated frequency: 50hz
8. Rated voltage: 380V
9. Connection: The stator winding is connected in Y for 132kW and below and in for the rest. In Y with zero lead is also supplied.
YZR, YZ series of motor lines used to drive various types of lifting machinery and other similar equipment, special products; has a large overload capacity and high mechanical strength, so it is particularly suitable for those short or intermittent Periodic work system, frequent start, brake, sometimes overload and significant vibration and shock equipment.
Motor power rating and installation size in line with IEC72 recommended standards, power level and installation size of the corresponding relationship with the Japanese JEM1202 and West Germany DIN42681 similar and interchangeable.
The insulation class of the motor is divided into F and H. Class F is suitable for general conditions where the cooling medium temperature does not exceed 40 ° C. Class H is applicable to metallurgical sites where the cooling medium temperature does not exceed 60 ° C. Both motors have the same electrical performance.
Motor has a good seal, for the general place of the motor protection class IP44, for the metallurgical area of the motor housing protection class IP54.
