description An electric motor is disclosed that includes a stator winding (14) defining a plurality of poles (40), with the winding being controllable to switch between a first number of poles and a second number of poles. A rotor (40) rotatable within the stator (12) includes a first group of magnetic flux barriers (26) being without permanent magnet material and a second group of magnetic flux barriers (26) at least partially filled with a permanent magnet material (28). A method of operating a line-start electric motor is also disclosed.
