Patent ID: 10756590

Abstract:
A stator (1) includes a plurality of divided cores (3) arranged in circumferential direction to constitute a stator core (2), and a holder (4). Stator coils (5) are wound around the individual divided cores (3). The divided core (3) includes a tooth part (6), and an insulator (13) around which the stator coil (5) is wound. A plurality of projection portions (5a) are formed in the stator coil (5) when the stator coil (5) is wound around the insulator (13). The projection portions (5a) are wound on only short sides of the insulator (13), resulting that the stator coil (5) does not protrude from the long sides of the divided core (3), and when the divided cores (3) are arranged in the circumferential direction to constitute the stator (1), the stator (1) is normally driven without the stator coils (5) of the neighboring divided cores (3) contacting each other.
