A New Generation of Axial Flux EV Motors | Design News

 · To produce rotation in a synchronous BLDC motor, windings of copper wire—called the stator—surround the rotor and interact with the magnetic fields of the permanent magnets. By carefully energizing different regions of the stator at exactly the right time, a rotational force can be imparted to the rotor and the motor spins.

Induction motorWikipedia

An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage type.

CHAPTER- 9 HYDRO GENERATOR, CHARACTERISTICS

CHAPTER- 9 HYDRO GENERATOR, CHARACTERISTICS AND PERFORMANCE 9.1 GENERAL The electric generator converts the mechanical energy of the turbine into electrical energy. The two major components of the generator are the rotor and the stator. The rotor is the rotating assembly to which the mechanical torque of the turbine shaft is applied.
