ABSTRACT:
Brushless repulsion motors are presented, in which rotor coils switching signal detectors are selectively located in spaced angular relationship on the rotor and signaling sources are distributed around all or most of the stator circumference to allow looser tolerances for motor manufacturing and improved controllability of rotor coil actuation during operation. Asymmetric stator poles are also provided for brushless repulsion motors to mitigate torque ripple and vibration, in which the shape of the stator pole tips is tailored by varying the angular length of the pole section.
