Electric Motor

1. Brief Summary of Products 1.1 YZR and YZ series crane motors are latest design types, featured with high mechanical strength, and the capability of overload is good. Especially it is suitable for drive all kinds of crane machine and metallurgical machine. (YZRWinding Rotor Three Phase Asynchronous Motor, YZSquirrel Cage Type Motor) 1.2 Normal Working Environments: (1.2.1) Temperature of Cooling Medium: Not more than 60(in metallurgy industries), not more than 40(in crane industries); (1.2.2) Altitude: Not more than 1000 meters; (1.2.3) Frequent and significant mechanical vibration & shocks. 1.3 Normal Working in Load Conditions: (1.3.1) Frequent starting and frequent reversion; (1.3.2) Frequent electric and mechanical braking. 1.4 Rated frequency is 50Hz, and rated voltage is 380V. 1.5 Connection Types: Y (≤132Kw), (132Kw). 1.6 Description of Types Such as: YZR132M1-6 (YAsynchronous; Zfor crane and metallurgical applications; RWinding rotor; 132centre height; MLength of frame; 1Code of stator core; 6Poles) 1.7 The Relation between Output Power and Speed: (1.7.1) The relation between output power and speed as the table 1 (standard duty is S340%).
