ABSTRACT:
A pulse generator combined with a micromotor is constructed by a disc shaped rotary magnet secured to the shaft of the motor and magnetized in the axial director, a rotary yoke made of magnetic material and provided with a plurality of equally spaced magnetic pole teeth extending in the axial direction, a magnetic stationary yoke secured to the casing of the micromotor and disposed to oppose the magnetic pole teeth of the rotary yoke, and a printed board interposed between the stationary yoke and the rotary yoke and secured to the motor casing. The printed board is formed with a wavy continuous electroconductive pattern on a circle facing the magnetic pole teeth so as to induce electric pulse signal by the flux produced by the magnetic pole teeth. The printed board is also formed with output terminals and source terminals connecting the micromotor to an electric source.
