Jan 04, 2008· Being a universal motor, it will also run on DC. For variable speed, use a 180vdc "pulse width modulated" motor drive. They are fairly common. The PWM will preserve torque at lower speeds, unlike a variac or triac chopper drive. If the 180vdc limits the top end power, use a DPDT switch and bypass the drive for 220vac at full speed/power.
Speed Switch Overview. A speed switch senses rotating shaft speed, comparing it to one or more settable over/under/zero speed alarm trippoints. A shaft speed sensor detects magnets embedded in a shaftmounted pulser wrap/disc. As the shaft rotates, the passing magnets are detected across an airgap as pulses with frequency proportional to ...
