PURPOSE:To reduce the number of component parts and to simplfy the assembling work for the subject motor by a method wherein an electronic parts group is installed on a printed substrate, and this printed substrate is attached to a coil frame. CONSTITUTION:A square hole 13 is formed on the side wall of a concavity 13 which was formed at one end of the coil frame 12, one end of a stator 14 is inserted from the square hole 13a, and one end of a core is fixed by caulking. Then the concavity 13 is covered by the printed substrate 7 whereon the electronic parts group such as an integrated circuit and the like, with which a reference frequency and a driving frequency are divided are installed. Thereupon, as the number of component parts can be reduced, the assembling work can be performed easily. |
