Since China is very good at producing computer mother boards at low cost, perhaps it can also put electronic car motor drives in mass production to make them cheap. But for now, wound field DC motors with brushes are entirely adequate for automobile use and can even provide a high level of regeneration without a single transistor in the vehicle and at far less cost.

Whilst the largest electric and diesel electric locomotives may use induction motors, the inverter drives are far to expensive for the limited energy use of automobiles in average service. Glass or carbon fiber reinforcement of critical parts of the armature and comutator can have the motors operate at much higher speeds. The chinese manufacturers would do well to forget about induction motors entirely and go right to switched reluctance motors that have even higher capacity at the same weight and less copper with higher efficiency. The drives are more complicated to operate but don't require any more silicon area capacity. High temperature Silicon Carbide transistors are now the latest for motor drives. China should make them too...hg...
