Advantages & Disadvantages

Induction Motors (have no natural magnets, rely on electricity to create a temporary magnetic field)

Advantages	Disadvantages
Lower Cost	Lower Torque
Low Spin Loss	Lower Efficiency

Permanent Magnet Motors

Advantages	Disadvantages
Higher Torque	Higher Spin Loss
Higher Efficiency	"Can't Turn Off"

EVs that use Permanent Magnet Motors

• Nissan Leaf - EM61, EM57

• Later Tesla Model S

Tesla model S/X only use ACIM motors front/back

Tesla Model 3/Y uses PMSM motor in the back and ACIM motor at the front. Its because of low spin loss ACIM is prefered as secondary motor...

Nissan Leaf uses PMSM IPM

BMW I3 uses PMSM IPM

Toyota Prius uses PMSM

Mitsubishi Outlander PMSM IPM
