ASYNCHRONOUS MOTOR WITH FEATURES CREATING MAGNETIC FIELD DISTURBANCE
First Claim
1. An asynchronous motor comprising:
- a stator including a plurality of windings and being configured to generate a rotating magnetic field when a current is provided to the plurality of windings;
a rotor positioned within the stator and configured to rotate relative thereto responsive to the rotating magnetic field; and
a component separate from the stator and the rotor and positioned within the rotating magnetic field, the component being configured to alter a magnetic reluctance of the rotor so as create a disturbance in the rotating magnetic field.

Abstract
A component for introducing disturbances into the magnetic field of an asynchronous motor by altering a reluctance of the motor is disclosed. An asynchronous motor is provided that includes a stator having a plurality of windings that is configured to generate a rotating magnetic field when a current is provided to the plurality of windings. The asynchronous motor also includes a rotor positioned within the stator configured to rotate relative thereto responsive to the rotating magnetic field and a component separate from the stator and the rotor that is positioned within the rotating magnetic field, with the component being configured to alter a magnetic reluctance of the rotor so as create a disturbance in the rotating magnetic field.

12. An asynchronous motor comprising:
-
a stator including a plurality of windings and being configured to generate a rotating magnetic field when a current is provided to the plurality of windings; a rotor positioned within the stator and including a rotor core and a plurality of rotor bar conductors, the rotor configured to rotate relative to the stator responsive to the rotating magnetic field; and a component positioned adjacent to the rotor and configured to alter a reluctance of the asynchronous motor so as to generate a disturbance in the rotating magnetic field; wherein the disturbance in the rotating magnetic field generated by the component introduces a current signal into a stator phase current spectrum of the stator. - View Dependent Claims (13, 14, 15, 16)
