IPC: H02P7/29
Filed: 1981-08-14
Abstract: PURPOSE:To reduce radio noises and other noises by conducting chopping with high frequency when a DC motor is revolved at low speed, and with low frequency when it is revolved at high speed. CONSTITUTION:When a DC motor 2 is revolved at relatively low speed, the value of the variable resistance 16 of a pulse generator 1 is set to be relatively small. Thereby the pulse width of a pulse output VG controlling a driving element 4 becomes small, its period becoming relatively small and its frequency high. The effective value of the output becomes low. On the occasion when the DC motor 2 is revolved at relatively high speed, the value of the variable resistance 16 is set to be relatively large. Thereby the pulse width of the pulse output VG becomes large, its period becoming relatively large and its frequency low. The effective value of the output becomes high on this occasion.
