There is no magnets in an induction motor so is this even possible.
No, given which you furnish a source of three area capability to energise the sphere windings. with out that, you purely have some coils of cord spinning close to different coils of cord. No magnetic fields, no capability generated.
The answer is that you need a field. Just how that field is generated varies. In some cases, remanence is used to initiate the magnetizing current. In others, external sources are used.
Hi, A 3 phase induction runs in generating mode under the condition: when the motor slip becomes negative i.e. (s < 0). In other words, a 3 phase induction motor runs in generating mode when the rotor speed is made to exceed the speed of rotating magnetic flux i.e. the synchronous speed. Such condition can be achieved by coupling the rotor with a prime mover like any engine or another motor and then, run it at a speed higher than the synchronous speed. Under such condition,the motor is known as Induction Generator.
A vehicle's charging system is a three phase alternator - and they work just fine AC or when the output is rectified to DC.
