PURPOSE:To automate the soldering work to the land of a terminal line, by forming the land of a printed circuit board so that it may be positioned on the extension lines of one side of an internal line and one side of an outline of a coil. CONSTITUTION:On both corresponding sides of the circumference of a hole 3a through which a rotor shaft goes a circular opening 5 is formed to a printed wiring board 3. Coils 1, are arranged e.g. in a group of three (3) piece so as to be nearly annularly as a whole to this circular opening 5 and secured to a yoke 4. In the nearly annular region between the hole 3a of the printed circuit board 3 and a circular opening 5 a land 6 is formed to solder the lead wires la and 1b of each coil. Each land 6 is formed in square so that it may be positioned on the respective extension of the internal line of a coil side 1c and of the outline of a coil side 1d of each coil 1 arranged nearly annularly.
