How to improve EV traction motor efficiency

Charged EVs

For example, torque is proportional to magnetic flux intensity, which itself is proportional to the product of current and the number of turns in each armature winding, so doubling the number of turns cuts the required current to produce the same torque in half. Resistive losses aren’t just a problem at high torque (i.e.
