The invention provides a single-phase motor. The motor comprises an excitation part and an armature part. The excitation part comprises N magnets, so 2N magnetic poles are formed in the excitation part through the N magnets. The armature part comprises 2N tooth parts and N coils wound on the tooth parts. 2N pole parts are formed on the 2N tooth parts, wherein N is an integer larger than 1. According to the invention, by fully using the magnets, the quantity and the assembling work of permanent magnets in the single-phase motor are reduced and the motor production cost is reduced. 种单相电机，包括励磁部分和电枢部分，所述励磁部分包括N个磁铁，所述N个磁铁使得所述励磁部分形成2N个磁极，所述电枢部分包括2N个齿部以及缠绕于所述齿部上的N个线圈，所述2N个齿部形成2N个极部，所述N为大于1的整数。利用本发明，能充分利用磁铁，减少单相电机中永磁磁铁的数量与组装工作，节约电机生产成本。
