3-phase, 4-pole electric induction motor

The motors in a Tesla or other EV are not built like an industrial type induction motor. In an off the shelf motor the windings are made of many small diameter wire per pole. The EV motors have a smaller number of very large diameter wires per pole.
Even though the horsepower may be the same between the two different motors the way they are used is different. An industrial type motor is used at a set (due to the pole count) speed. An EV motor is more of a variable speed motor, spending a lot of it's time at a slow speed that would kill an industrial motor from heat.
