A motor, a pump and a cleaning apparatus are provided. The motor (22) includes a stator and a rotor (26) rotatable relative to the stator. The stator includes a stator core (54) and stator windings (56) wound around the stator core. The stator core includes a pair of opposing poles (62) and a yoke connected between the poles. Each pole has a pole arc surface (66) facing the rotor, with an air gap formed between the pole arc surface and the rotor. The pair of poles includes opposing circumferential end portions (74) spaced apart from each other, and a ratio of a distance (a1) between the circumferential end portions to a minimum width (a2) of the air gap between the pole arc surface and the rotor is less than 2. |
