Permanent magnet motors currently have been established as a favored option in the ever-growing electric automotive industry. In the presence of strong rare earth neodymium material enables substantial increase in power density.
A wide range of studies and analyses have been developed on the losses in the permanent magnets of inverter-fed motors . The studies focus on different types of motors, such as surface mounted PM synchronous motors and IPMSMs, as well as on various types of permanent magnets such as NdFeB and SmCoalloys .
From the perspective of green and sustainable development, permanent magnet motor can reduce energy loss and meet the requirements of sustainable development through the reasonable selection and utilization of permanent magnet materials, the design of motor structures, and advanced transmission control technology.
