A stepper motor (or step motor) is a brushless, synchronous
electric motor that can divide a full rotation into a large
number of steps. The motor's position can be controlled
precisely, without any feedback mechanism (see Open-loop
controller). Stepper motors are similar to switched
reluctance motors (which are very large stepping motors
with a reduced pole count, and generally are closed-loop
commutated.)

An induction motor (IM) is a type of
alternating current motor where power is supplied to the
rotating device by means of electromagnetic induction.
