In 2021, Germany's Mahle released a new magnetless motor that does not require rare earth materials
August 01, 2023

In 2021, Germany's Mahle released a new type of magnetless motor that does not require rare earth materials.Moreover, the efficiency of this motor can reach more than 95% under almost any working condition, which was only achieved by Formula E racing cars before.

Permanent magnet synchronous motors and non-magnetic induction AC asynchronous motors.
August 01, 2023

There are two types of motors currently used in electric vehicles - permanent magnet synchronous motors and non-magnetic induction AC asynchronous motors.Permanent magnet synchronous motor technology is mature and efficient, so it is used in most electric vehicles with single motor designs. For example, the Tesla Model 3 long-range version has a rear single motor.But the permanent magnet motor has a big disadvantage - it requires the use of precious rare earth materials.There are also shortcomings such as the slightly higher price of permanent magnet synchronous motors and the easy demagnetization at high temperatures.

Is Tesla Motors 'getting rid of' rare earths and magnetless motor technology a new direction?
August 01, 2023

Colin Campbell, Tesla's vice president of powertrain engineering, said that Tesla's next-generation electric motor will not use rare earth materials at all, and the next-generation platform will also reduce silicon carbide by 75%.Rare earth materials actually exist in our lives. For example, the magnets we played with when we were children are rare earth materials.Rare earths can be used in speakers and various motors, and permanent magnet motors used in new energy vehicles are major users of rare earth materials.China is the world's largest exporter of rare earths.
