1.1 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.
1.2 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.
1.3 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.
1.4 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.
YZR winding slip ring motor is suitable for lifting metallurgical related mechanical equipment. The motor has high overload capacity and mechanical strength. It is suitable for short-term or intermittent periodic working system, frequent starting, braking, and significant vibration. With impact equipment.
This type of motor casing has a high strength cast iron casing, the motor junction box is located at the top of the motor, the motor fan is a good performance cast aluminum fan, and the motor slip ring uses a high quality copper slip ring.
