When the three phase control is employed to power a DC motor, a fourth single phase circuit is used to provide full wave rectified voltage and current to the field winding of the motor. Means are provided for simultaneously adjusting the current and voltage output of the three phase and ...
The Geckodrive controller I use is the G320, which is designed to control a permanent-magnet DC (PMDC) servomotor having a quadrature encoder. While such servomotors are expensive, it is possible to convert an ordinary DC motor into a servo by the addition of a rear shaft and encoder. Th...
