I'm doing simulations of EV power supplies including an inductive load. The simulator needs a value for coil inductance. Any ideas?

Induction of electric vehicles should be analyzed according to the inductance value of the coil.

In all its iterations, the induction motor induces magnetism that is leveraged to output rotary motion. The stationary outer stator is connected to an external electrical power source; this is fed to the rotor’s poles in a rotating progression that causes revolutions of the magnetic field within the motor. Conducting bars in the rotor interact with the stator’s magnetic fields; current is induced in those bars, which in turn generate magnetic fields that are attracted to those of the stator.

Illustrated here are magnet-induced flux and current-induced flux, upon which all electric motor operation is based.

As the rotor’s induced current and magnetism cause it to follow the field generated by the stator, rotary motion is output.

Because an AC induction motor increases the flux enclosed by its stationary coils, it is a transformer with a rotating secondary (rotor). The rotor current’s effect on the air gap flux causes torque.

AC induction motors are built by manufacturers according to established National Electrical Manufacturers Association (NEMA) standards in myriad fractional and integral horsepower ratings and associated frame sizes. These AC induction motors are quite common — the workhorse of the industry.
