Neodymium vs. SmCo Magnets for Hybrid Electric Vehicles

Permanent Magnets Dominate EV

Vehicle electrification is a growing market for rare earth magnets. Consumption of rare earth magnets in transportation is estimated to rise from 7,000 tons in 2015 to 17,000 tons in 2020. Government mandates to reduce pollution, as well as high gasoline prices, are driving users to purchase more environmentally friendly vehicles. Permanent magnet machines are currently the leading choice for high performance automotive applications. The rotor’s well-balanced magnetic field and the lower stator current requirement, paired with very strong positional control, result in a higher motor efficiency. Two common choices for electric vehicle applications are neodymium magnets and samarium cobalt magnets, and each has its advantages.

Overcoming Design Challenges in High Performance Motors



Smaller Motors, Bigger Design Challenges

Permanent magnet (PM) motors for EV applications have unique design challenges. As electric motors become smaller and faster, designers must consider the potential effects of electrical drive frequencies, magnetic eddy currents, laminated steel core loss, mechanical stresses on the quickly rotating shaft (rotor dynamics), and electrical control of the motor through the inverter.
