motor

motor YD series pole-changing multi-speed three phase induction motors are derived from Y series motors,it can change speed easily. YD series is one of the main derived series of Y series,a national unified designed latest product in China and a replacement type for the JOD2 series .The speed of this series motor can be changed step by step accroding to the requirements of load characteristics, thereby reaching the aims of economizing on electricity and simplifying the system of speed variation.This series of motor has great starting torque and low noise and vibration,and its mounting dimensions are complied with the standard of the International Electrotechnical Commission(IEC),it has a fairly good interchangeability as compared with the similar products of the same kind so that it is easy to maintain and used widely in the industrial departments of machine tools,chemical industry ,textile,metallurgy and mine,etc.The degree of protection of the motor is of IP44, cooling mode is IC0141,and B-class insulation is adopted,the mode of rating is contineous running.NotesThe connection strap connection must correspond to power&speed . Operating Conditions Ambient Temperature-15 +40 AltitudeNot Exceed 1000m Rated Voltage range percent Not Exceed ± 5%
