I. Overview of Sima YD series variable pole multi-speed motor
    YD series variable pole multi-speed three-phase asynchronous motor is one of the main derivative series of Y series (1P44) three-phase asynchronous motor. This series of motors has the ability to change the speed stepwise according to the requirements of the load nature, thus achieving reasonable matching of power and simplifying the characteristics of the shifting system. It is one of the ideal powers for mechanical system to save energy. It has been widely used in industrial and agricultural sectors such as machine tools, mining, metallurgy, textile, printing and dyeing, chemical industry, and agricultural machinery.
    YD series variable pole multi-speed three-phase asynchronous motor has the characteristics of high efficiency, large stall torque, low noise, low vibration and safe and reliable operation for other series of motors of the same type in China. The motor complies with the "YD series (1P44) variable pole multi-speed three-phase asynchronous motor technical conditions JB/T7127-93".
    YD series variable pole multi-speed three-phase asynchronous motor adopts Class B insulation, rated voltage is 380V, rated frequency is 50Hz, enclosure protection grade is IP44, cooling mode is IC411, continuous operation (S1). The operating point of the motor is not more than 1000m above sea level; the ambient air temperature varies with the season, but does not exceed 40°C; the minimum ambient air temperature is -15°C; the average wettest month average maximum relative humidity is 90%, and the monthly average monthly minimum temperature Not higher than 25 ° C.

    The corresponding relationship between the power level and power level of the YD series motor and the installation size is equivalent to that of the same type of advanced products abroad. Therefore, it has good interchangeability with advanced products of the same type abroad. It is convenient for single machine or export with machine tool, and can also be used as spare motor for the same type of motor in imported equipment.
Second, the Sima YD series variable pole multi-speed motor model description:
YD 132 M 2 - 6/4/2: "Y" means asynchronous motor, "D" means multi-speed, "132" means motor center height (mm), "M" means the frame length code, and "2" means the core The length code, "6/4/2" indicates the motor pole ratio.
