2018-11-28  Electric and hybrid vehicles also take advantage of electromagnetic induction. One limiting factor that inhibits widespread acceptance of electric vehicles is that the lifetime of the battery is not as long as the time you get to drive on a full tank of gas. To increase the amount of charge in the battery during driving, the motor can act as a generator whenever the car is braking, taking ...

The paper presents a mathematical model of an asynchronous squirrel-cage motor with arbitrarily asymmetrical stator windings. The structure of the mathematical model equations is analysed in detail using the assumption about the symmetry of the rotor cage. A particular arrangement of the mutual inductance matrix of stator windings and rotor cage meshes is shown.
