摘要
真空干泵驱动电机散热困难,需要严格控制其的温升,进而保证系统的长时间运行。以30 kW驱动电机为研究对象,设计了一台异步电机和一台18/12极双凸极永磁电机。两种电机的外形尺寸和功率等级等条件相同。同时,两种电机的冷却方式均采用机壳通有螺旋水道的水冷,分别对两种电机进行了温度场分析。分析结果表明,在额定运行时双凸极永磁电机具有更低的整体温升,更加适用于真空干泵机组。
The heat dissipation of the vacuum dry pump drive motor is difficult,and it is necessary to strictly control its temperature rise to ensure the long-term operation of the system.Taking a 30 kW drive motor as the research object,an asynchronous motor and an 18/12 pole double salient permanent magnet motor are designed.The external dimensions and power levels of the two motors are the same.At the same time,the cooling mode of the two motors is water cooling with spiral water channel in the casing,and the temperature fields of the two motors are analyzed respectively.The analysis results show that the doubly salient permanent magnet motor has a lower overall temperature rise during the rated operation,which is more suitable for the vacuum dry pump units.
