An inner-rotor motor for preventing the formation of an electrical conducting path between an iron core and a housing of the motor includes a stator and a rotor. The stator includes the housing, an insulating layer and the iron core. The insulating layer is arranged between the housing and the iron core and prevents the electrical conducting path from forming between the housing and the iron core. The rotor includes a shaft rotatably coupled with the housing, and a permanent magnet unit is arranged around the shaft.
