Abstract

The angular position sensor is based on a coil rotating between two magnetic poles, its output providing the position data. A stator centred on a shaft (8) driven at half the motor rpm consists of a non-magnetic former (12) holding a coil (23) wound over a ferrite core (18) tangential to the shaft and shaped pole pieces. The shaft carries two permanent magnets which are parallel to the ferrite cores in their closest position with their north and south poles alternating around rotor. Four wire groups in quadrature carried on a non-magnetic disc integral with the shaft above the level of the stator winding ensure a rapid voltage rise and fall in the coils of about 20 m secs duration.
