    • 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.
    • 用于永磁无刷电动机的转子包括轴,固定在轴上的转子芯和嵌入转子芯中的磁体。 转子芯限定沿其圆周方向布置的多个间隔开的第一狭槽和多个间隔开的第二槽,每个第二槽位于两个相邻的第一槽之间,并且每个第一槽位于两个相邻的第二槽之间。 第一永磁体被容纳在第一槽中,第二永磁体被容纳在第二槽中。 每个第二磁体位于两个相邻的第一磁体之间,并且每个第一磁体在圆周方向上位于两个相邻的第二磁体之间,并且第一磁体在转子芯的径向上被磁化,并且第二磁体在圆周方向上被磁化。
