and various stator windings including copper/aluminium Litz wires and HTS coils are compared regarding stator AC loss as well as machine power-to-weight ratio (PTW). The result indicates that ...

A stator, mainly a set of coils, is a stationary part in an electric motor. It creates a rotating magnetic field when power is passed through it and interacts with the rotor to generate electricity.

An analytical formula for the mutual inductance of coils in a WPT system considering the influence of stator and rotor materials is proposed, determining the rotor attitude through regional ...
