Permanent-magnet motor rotor, permanent-magnet motor and method for processing a permanent-magnet motor rotor

A permanent-magnet motor, comprising a permanent-magnet motor rotor, wherein the permanent-magnet motor rotor comprises:

• a rotatable shaft;
• a silicon steel sheet member sleeved on the rotatable shaft;
• and
• a plurality of magnetic tiles secured around the silicon steel sheet member at intervals, wherein two circumferential ends of each of the plurality of magnetic tiles are inclined with respect to an axis of the each of the plurality of magnetic tiles and inclined in directions opposite to each other to form two beveled surfaces, and beveled surfaces, facing to each other, of two adjacent ones of the plurality of magnetic tiles are disposed in parallel.

A method for processing a permanent-magnet motor rotor, the method being applicable to a permanent-magnet motor rotor wherein the permanent-magnet motor rotor comprises:

• a rotatable shaft;
• a silicon steel sheet member sleeved on the rotatable shaft;
• and
• a plurality of magnetic tiles secured around the silicon steel sheet member at intervals, wherein two circumferential ends of each of the plurality of magnetic tiles are inclined with respect to an axis of the each of the plurality of magnetic tiles and inclined in directions opposite to each other to form two beveled surfaces, and beveled surfaces, facing to each other, of two adjacent ones of the plurality of magnetic tiles are disposed in parallel, and
• the method comprising:
• sleeving a silicon steel sheet member on a rotatable shaft;
• beveling a plurality of magnetic tiles corresponding to a plurality of poles of the permanent-magnet motor such that two circumferential ends of each of the plurality of magnetic tiles are inclined with respect to an axis of the each of the plurality of magnetic tiles and inclined in directions opposite to each other to form beveled surfaces;
• and
• securing the plurality of magnetic tiles around the silicon steel sheet member at intervals and parallelizing beveled surfaces, facing to each other, of two adjacent ones of the plurality of magnetic tiles to form the permanent-magnet motor rotor.
