The YD series variable speed three-phase asynchronous motor is one of the main derivative series of the Y series (IP44) three-phase asynchronous motor. This series of motors is one of the ideal power sources for mechanical systems to save energy due to its ability to change speed step by step according to the requirements of load properties, thereby achieving reasonable power matching and simplifying the variable speed system. It has been widely used in industrial and agricultural sectors such as machine tools, mining, metallurgy, textiles, printing and dyeing, chemical industry, and agricultural machinery.
The YD series variable pole multi speed three-phase asynchronous motor has the characteristics of high efficiency, large locked rotor torque, low noise, small vibration, and safe and reliable operation compared to other series of motors of the same type in China. The motor complies with the technical specifications JB/T7127-1993 for YD series (IP44) variable speed three-phase asynchronous motors.
The YD series variable pole multi speed three-phase asynchronous motor adopts B-level insulation, with a rated voltage of 380V, a rated frequency of 50HZ, an enclosure protection level of IP44, a cooling method of IC411, and continuous operation (S1). The altitude of the motor operating location shall not exceed 1000m; the ambient air temperature varies with the seasons, but shall not exceed 40 ℃; The minimum ambient air temperature is -15 ℃; The average maximum relative humidity of the wettest month is 90%, and the average minimum temperature of that month is not higher than 25 ℃.
The power level and the relationship between power level and installation size of YD series motors are comparable to advanced products of the same type abroad. Therefore, it has good interchangeability with advanced products of the same type abroad. Easy to export as a standalone or machine tool, it can also be used as a backup motor for imported equipment of the same type.
