A switched reluctance (also known as variable reluctance) motor has no
permanent magnets or brushes. Coils connected in series around a pair
of opposite stator poles are energised by a DC current to create lines
of magnetic flux. This causes a pair of teeth on the iron rotor to align
themselves with the stator poles. This sequence is continued around the
stator poles causing the rotor to rotate. Suitable for high torque and
high speed applications, applications include hoists, cranes, conveyer
belts and vacuum cleaners.
