为了满足最新电机能效等级国家标准的要求,提高电机的运行效率,以一台55 kW的充水式潜水电机为例,提出了一种永磁辅助同步磁阻电机(PMASRM)转子电磁设计方法,结合转子再制造技术,取代传统的潜水感应电机转子,将其改造成为潜水PMASRM。设计的潜水PMASRM和传统的潜水感应电机具有相同的定子铁心结构和绕组形式,提高了材料的利用率,降低了制造成本。有限元仿真结果表明,改造后的潜水PMASRM效率比潜水感应电机得到有效提高。

[Abstract]
In order to meet the requirements of the latest national standard of motor energy efficiency grade and improve the operation efficiency of the motor, a 55 kW wet submersible motor is taken as an example, and a rotor electromagnetic scheme design method of permanent magnet assisted synchronous reluctance motor (PMASRM) is proposed. Combined with rotor remanufacturing technology, the rotor of traditional submersible induction motor is replaced and transformed into submersible PMASRM. The designed submersible PMASRM has the same stator core structure and winding form as the traditional submersible induction motor, which improves the utilization rate of materials and reduces the manufacturing cost. The finite element method results show that the efficiency of the modified submersible PMASRM is improved effectively compared with the submersible induction motor.
