When do the magnets rotate??? (1 Viewer)

When are the magnets rotated in the stator??? instead of the coil???

motors... generators... AC ... DC ???

Thankyouuu

In most large scale AC generators a rotating electromagnet is used to induce currents in the stator.
In AC induction motors a rotating magnetic field (not magnet) is used to produce motion.

dont know whether youll bother to look at this its a really late reply but, whatever we build (or the teacher demonstrates in the lab) is a simple AC/DC motor and although fundamentally similar they do differ from "real" ac/dc motors..

As helper said "real" or large scale ac motors will contain a rotating field structure. Other differences include:

- Simple usually contains a field structure consisting of a common bar magnet, "real would used electromagnets to intensify the the magnetic flux.
- Simple would use a single coil, a real would used two coils at 90 degress to each other which increases torque and hence efficiencey of the motor
- An real AC generators would contain coils which a 120 degrees out of phase to produce three sets of voltages....

hope i helped =]
