Abstract
A coil assembly for sensorless rotor angular position control of a single phase permanent magnet motor. The coil assembly is positioned axially adjacent one end of the motor's rotor core in magnetic coupling relationship with the rotor and substantially independent of the magnetic coupling relationship between the main winding of the motor's stator and rotor. The coil assembly comprises a coil of wire and a coil fixture for holding the coil of wire.
