I posed a rather cluttered question earlier, by including the servo motor, which is, as pointed out by several of you, is not a specific kind of motor, but a closed loop control system involving servo mechanism, to control the speed or position of the motor being used(AC or DC).
However, the question of switched reluctance motor vs the stepper motor still remains ON.
All in all, I know is:- steppers generally are run on open loop and have high number of poles to allow for small and precise step changes, while SRM on the other hand requires a position feedback, at the very least; so that current pulses can be switched on to the stator windings in an orderly fashion, to generate some useful motoring or generating torque.
So, if someone have heard of srm and know the proper arguments to differentiate between them, it would really be helpful.
Please, correct me if I am wrong about the difference I have written.
