在不久的将来，由于资源风险和汽车电气化带来的价格上涨，需要减少重稀土元素的使用。本文比较了两种相同尺寸的混合动力电动汽车牵引电机，分别采用钕烧结磁体和重稀土自由磁体。我们设计了两个内部永磁同步电动机的变化，只有转子的设计和材料。研制了一种性能和尺寸与钕烧结永磁电机相当的新型无稀土永磁电机。转子形状设计为同步磁阻电机的转子形状，以克服无稀土电机转矩大的缺点。通过一系列实验验证了电机的性能。
In the near future, usage of heavy rare-earth element needs to be reduced, due to resource risk and rising price with vehicle electrification. This paper compared two hybrid electric vehicle traction motors of the same size using Nd sintered magnet and heavy rare-earth free magnet. We designed two interior permanent magnet synchronous motors varying only the rotor design and material. A new motor was developed using heavy rare-earth free magnet with performance and size equal to Nd sintered motor. The rotor shape was designed as the one of a synchronous reluctance motor to overcome the lack of heavy rare-earth free motor torque. The motor performance was verified with a series of experiments.
