Permanent magnet rotor brushless motor
Abstract:
A rotor for a permanent magnet brushless motor includes a shaft, a rotor core fixed to the shaft, and magnets embedded in the rotor core. The rotor core defines a plurality of spaced first slots arranged in a circumferential direction thereof, and a plurality of spaced second slots, each second slot being located between two adjacent first slots and each first slot being located between two adjacent second slots. First permanent magnets are received in the first slots and second permanent magnets are received in the second slots. Each second magnet is located between two adjacent first magnets and each first magnet is located between two adjacent second magnets in the circumferential direction, and the first magnets are magnetized in radial directions of the rotor core and the second magnets are magnetized in the circumferential direction.
