Abstract
A rotor for an electric motor which includes permanent magnets is formed so that the possibility of demagnetization of the permanent magnets is reduced. The rotor has at least one permanent magnet embedded in a magnetically conductive rotor core, and at least one flux path in the rotor core, for a magnetic flux caused by a magnetic stator field generated by a stator of the electric motor. The rotor core is realized, with respect to at least one of the flux paths, with a magnetically conductive shunt that bridges at least one of the permanent magnets for the magnetic flux that is caused by the stator field.
Claims15
A rotor for an electric motor, the rotor comprising:
- a magnetically conductive rotor core and at least one permanent magnet embedded in said rotor core, said rotor core having at least one flux path defined therein for conducting a magnetic flux caused by a magnetic stator field generated by a stator of the electric motor;
- at least one magnetically conductive shunt formed in said rotor core for the at least one flux path, said at least one magnetically conductive shunt bridging said at least one permanent magnet for the magnetic flux caused by the stator field.
