Wherever motion must start, stop and reverse on cue.
Our motors turn slowly, start and stop instantly and reverse without a pause. Any machine that needs positive, low-speed positioning can use them.
Where our motors work
The same control at 60 RPM serves all of these machines.
Antenna drives
Slow, precise positioning in both directions.
Copiers
Controlled, repeatable motion.
Printing machines
Reliable start-stop drive.
Servo voltage stabilizers
Moves the carbon-brush arm until the output voltage is right.
Switches, rheostats and dimmerstats
Remote control: turn a knob from a distance.
Synchronous timers
Steady speed locked to mains frequency.
Valve controls
Open, close and hold on command.
X-ray scanning
Smooth, low-speed travel.
Inside a servo voltage stabilizer.
When mains voltage drifts, the control card signals the motor. The motor drives the carbon-brush arm along the variac until the output is corrected, then stops within 5°. On multi-phase stabilizers, two or more motors run in sync within 3.6°.
