Electric motor i.e. brushless synchronous motor, has Hall effect sensor for measuring magnetic flux resulting from magnets of rotor, where sensor is arranged opposite to rotor in axial direction and spaced from rotor in axial direction

摘要

The motor (2) has a stator (4) including coils to be traversed by electric current. A rotor (6) includes permanent magnets (36) accommodated in a support structure (38), where the rotor is intended to be rotated relative to the stator about a rotation axis (A) defining an axial direction. A Hall effect sensor (50) measures the magnetic flux resulting from the magnets of the rotor. The Hall effect sensor is arranged opposite to the rotor in the axial direction and spaced from the rotor in the axial direction.
