Series motor full-wave control circuit

Published:2011/3/21 1:38:00 Author:Allen | Keyword: Series motor, full-wave control | From:SeekIC

The circuit adopts transistor phase-shift trigger and one-way thyristor to control the full-wave voltage of series motor circuit, so it can control motor speed at a wide range. Resistor R5 in series on one-way thyristor main circuit constitutes negative feedback, which can stabilize the speed. The values of R5 is 0.1-1 Ω. Br diode rectifier bridge can convert AC to DC.
