Abstract:
1. A brushless synchronous motor to be connected to a power supply circuit and a control circuit for controlling said power circuit to supply multi-phase electric power supply to said synchronous motor, said motor comprising: a stator core having a plurality of stator teeth and a plurality of phase coils wound around bobbins that are fitted to said stator teeth; a rotor disposed opposite said stator; a housing for supporting said stator core and said rotor; a circuit board having a patterned circuit that connects said phase coils with a prescribed circuit; and a power supply terminal disposed in said housing to be connected to said power supply circuit; wherein each of said bobbins has a pair of coil terminals respectively connected to opposite ends of a respective one of said phase coils, each said terminal having a shoulder supporting said circuit board at a prescribed axial distance from said stator core and a projection connected to said patterned circuit.
