Abstract
An electric machine includes a stator and a permanent magnet flux-concentrating rotor. The permanent magnet flux-concentrating rotor has permanent magnets and pole pieces. The permanent magnets are engaged between the pole pieces. The electric machine also has at least one magnetic-field detector that is mounted on the stator. The at least one-magnetic-field detector is mounted on the stator in such a manner as to detect a magnetic field of the permanent magnets in a location that overlaps a peripheral region of the rotor when the machine if observed on the axis of rotation of the rotor.
