Rotor for an electrical machine and relative assembly method

摘要

A rotor for an electrical machine includes a laminated core having a main axis and a plurality of poles delimiting a plurality of radial seats extending along the main axis, each seat being delimited by a first and a second pole. The rotor includes a plurality of magnets inserted in the seats and a plurality of springs locking the magnets in the seats; the springs acting between each magnet and the first pole delimiting the relative seat for pushing each magnet towards the second pole delimiting the same seat.

1. A rotor for an electrical machine, comprising:
a laminated core having a main axis and a plurality of poles delimiting a plurality of radial seats extending along the main axis, each seat being delimited by a first pole of the plurality of poles and a second pole of the plurality of poles, wherein the first pole and the second pole alternate around the laminated core; a plurality of magnets inserted in the seats; and a plurality of springs locking the magnets in the seats, each spring of the plurality of springs being provided on the first pole of the plurality of poles, wherein for each first pole, the spring operates between one of the magnets and the first pole delimiting an adjacent seat for pushing the magnet towards the second pole delimiting the adjacent seat; each spring being positioned astride a relative first pole and pushing on two adjacent magnets to force the two adjacent magnets against faces of respective second poles delimiting the seats in which the two adjacent magnets are positioned, with the faces of the respective second poles being located on opposite sides of the two adjacent magnets relative to the spring.
