Abstract
A synchronous reluctance motor includes a rotor and a stator surrounding the rotor. The rotator includes a rotatable shaft and magnetic flux barrier layers arranged radially. One of the magnetic flux barrier layers closest to the stator is filled with a conductor, and one of the magnetic flux barrier layers closest to the rotating shaft is a void.
Claims14
A synchronous reluctance motor, comprising:
- a rotor;
- and
- a stator surrounding the rotor;
- wherein
- the rotor includes a rotatable shaft and magnetic flux barrier layers arranged radially;
- one of the magnetic flux barrier layers closest to the stator is filled with a conductor, and one of the magnetic flux barrier layers closest to the rotating shaft is a void;
- a total number of the magnetic flux barrier layers 2N+1, where N>1;
- more than N+1 of the magnetic flux barrier layers adjacent to the stator are filled with conductors;
- and
- at least a portion of the (N+2)th to 2Nth of the magnetic flux barrier layers adjacent to the stator are filled with the conductors or voids which do not include any of the conductors.
