Video Summary
- Tesla is using induction motors in their EV line but the Model 3 came up with the permanent magnet synchronous reluctance (IPM SynRM) motor.- IPM SynRMs are shown to achieve high-speed performance.
- IPM SynRM has a 2% higher efficiency than the induction motors.
- IPM SynRM runs cooler due to the absence of I²R loss.
- The IPM SynRM produces a wider range of higher torque values.
- Carbon fiber sleeving, a manufacturing breakthrough, is used to hold the magnets together and enable high speed range.
- The IPM SynRM does not need as much cooling as an induction motor.
