Abstract
A single-phase outer-rotor motor and a stator thereof are provided. The stator includes a stator core having a yoke and a number of teeth. Each tooth includes a tooth body and a tooth tip. A winding slot is formed between each two adjacent tooth bodies. A slot opening is formed between each two adjacent tooth tips. The tooth tip protrudes beyond the tooth body. Inner surfaces of at least part of the tooth tips facing the stator are formed with cutting grooves such that a portion of the tooth tip outside the cutting groove is capable of being tilted outwardly to enlarge the slot opening and deformed inwardly to narrow the slot opening.
