Abstract
Provided is an outer rotor type motor capable of reducing workload for wiring and connecting coil leads without reducing a coil space factor while keeping the motor small. Coil leads extracted from same-phase coils of respective stator units pass between pole teeth of the stator units, and are respectively connected to inter-phase connection terminals at one end and then connected in series with each other, the stator units comprises a plurality of individual same-phase stator units which are stacked together, and the inter-phase connection terminals are protruded from a main terminal body. A drive signal input terminal and external input terminals, to which the other ends of coil leads extracted from the respective phase coils are respectively connected, and a drive signal input terminal and an external input terminal, to which the other ends of coil leads extracted from the respective phase coils are respectively connected, are respectively connected and wired inside the main terminal body.
