Claims

[Scope of utility model registration request]

In a DC motor having a brush, an FC printed coil is etched as a stator coil of a frequency generator (hereinafter abbreviated as FG), which has a machine on the outer periphery of a brush holder that holds the brush to detect the rotor rotation speed of the motor. A ring-shaped permanent magnet is provided by a technique and is magnetized with multiple poles in the axial direction at the same pitch as the FG printed coil on a surface facing from the FG printed coil through a gap. The DC motor comprises an FC rotor magnet arranged concentrically with the printed coil, and in combination with the FG printed coil, a full-circumference integral type FG is formed therein.
