YD Series Pole Changing Multi-speed Three Phase Motor

YD series pole changing multi-speed three phase induction motor is the y series (1P44), one of the main derived series three-phase asynchronous motor. This series motors with load changes in the nature and levels, often at the request of speed, so as to achieve proper matching of power and simplify the transmission characteristics, is the ideal driver of mechanical systems to save energy. In machine tools, mining, metallurgy, textile, printing and dyeing, chemicals, machinery and other industrial and agricultural sectors are widely used. YD series pole changing multi-speed three phase induction motors for the domestic series motors have high efficiency, high locked rotor torque, low noise, little vibration, reliable operation and so on. Motors in accordance with "YD series (1P44) JB/T7127-93 variable-pole multi-speed three phase induction motor technology" requirement. YD series pole changing multi-speed three phase induction motors with class b insulation, rated voltage is 380V, rated frequency is 50Hz, casing protection degree is IP44, cooling method IC411, continuous duty (S1). Motor operation elevations do not exceed 1000m ambient air temperature changes with the seasons, but not more than 40 ?; minimum ambient air temperature was-15 degrees; most wet month with an average maximum relative humidity of 90%, while the monthly average minimum temperature is not higher than 25 degrees centigrade. YD series motor power ratings and power levels and mounting dimensions correspond to relations with foreign advanced products of the same type. Thus with foreign advanced has good interchangeability between products of the same type. For stand-alone or with supporting the export of machine tools, can also be used as alternate Motors Motors of the same type in the imported equipment.
