Claims14
An axial alignment system for a rotary electric machine, the axial alignment system comprising:
- a first fixing ring configured to be fixed to a shaft of a rotor of the rotary electric machine;
- a first permanent magnet ring fixed to the first fixing ring;
- a second fixing ring configured to be fixed to a static element of the rotary electric machine;
- and
- a second permanent magnet ring fixed to the second fixing ring;
- wherein:
- a surface of the first permanent magnet ring faces a surface of the second permanent magnet ring with an annular chamber therebetween;
- and
- a polarity of an entirety of said surface of the first permanent magnet ring is opposite a polarity of an entirety of said surface of the second permanent magnet ring, such that a magnetic attraction force is established between said surface of the first permanent magnet ring and said surface of the second permanent magnet ring in the annular chamber.

An axial alignment system for a rotary electric machine, the axial alignment system comprising:
- a plurality of first fixing rings, each configured to be fixed to a shaft of a rotor of the rotary electric machine;
- a plurality of first permanent magnet rings, each fixed to a respective one of the first fixing rings;
- at least one second fixing ring fixed to a static element of the rotary electric machine;
- and
- a plurality of second permanent magnet rings, each fixed to the at least one second fixing ring;
- wherein:
- a surface of each first permanent magnet ring faces a surface of a respective second permanent magnet ring with an annular chamber therebetween;
- and
- a polarity of an entirety of said surface of each first permanent magnet ring is opposite a polarity of an entirety of said surface of each respective second permanent magnet ring, such that a magnetic attraction force is established between each surface of the first permanent magnet ring and each surface of the respective second permanent magnet ring in the respective annular chamber.
