PURPOSE:To position a lead bush easily, and to miniaturize a stator by previously forming a notch section for fixing the lead bush to a printed substrate, fastening the lead bush, a core, etc. and integrally molding these bush, core, etc. by a resin. CONSTITUTION:A notch 4C in approximately the same size as a lead bush for protecting a lead wire is shaped previously to a printed substrate 4, and the lead bush 14 is fitted and fastened to the notch 4C. A positional sensor 7 and various drive-circuit parts (such as a driver IC 5, power transistor arrays 6a, 6b, etc.) are settled onto the printed substrate 4 while a stator core 1 on which windings 3 are wound is also mounted. These each part and the printed substrate are molded integrally by a synthetic resin. Accordingly, the lead bush 14 can easily be positioned, and the projecting size of the lead bush 14 can be scaled down. |
