Abstract

A rotor, motor, pump and a cleaning apparatus are provided. The rotor includes a shaft and two magnets fixed to the rotary shaft. Each magnet comprises a radial outer surface, a radial inner surface, and two connecting surfaces that connect the radial outer surface and the radial inner surface at opposite ends of the magnet. The radial outer surface has an arc section. The radial inner surfaces of the two magnets cooperatively define an inner bore for the shaft to pass therethrough. A ratio of a pole arc angle of each magnet to a 180-degree angle is in the range of 0.75 to 0.95.
