摘　　要：潜油电机槽满率低、振动大,增大了绕组绝缘损坏的风险。为此,提出一种定子模块组合式潜油电机(MCSPMM)结构,能够有效增大电机的槽满率,减小电机振动。但在高温高压的工作条件下,需要对这种特殊结构电机的温升进行进一步设计和校核。由于实际工况下电机温升测试困难,为了确保电机运行的稳定性,对超细长潜油永磁电机的温升进行了研究。其发热量可用热负荷进行近似考量并用有限元进行了验证,计算极限工况下电机的温升分布,为超细长MCSPMM的设计提供重要依据。Traditional submersible motors have low slot full rate and large vibration,which increase the risk of damage to the winding insulation.A structure of combined stator module submersible motor is proposed,which can effectively increase the slot full rate to reduce motor vibration.However,under the working conditions of high temperature and high pressure,the temperature rise of this special structure motor needs to be further designed and checked.Due to difficulties in motor temperature test under actual operating conditions,to ensure the stability of the motor running,temperature rise of ultra-slim long submersible permanent magnet motor is studied.Its calorific value can be approximated by thermal load and verified by finite element method.The temperature rise distribution of the motor under extreme conditions is calculated,which provides an important basis for the design of ultra-slim long modular combined submersible permanent magnet motor(MCSPMM).
