Position detectors provide motor-control logic


Posted on Dec 24, 2012

In the circuit of Figure 1, assume that a brush-type dc motor must drive a load back and forth between two endpoints on a lead screw. Optical sensors determine end of travel, and an SPDT switch selects to which end to send the load. The sensors themselves supply all the necessary directional logic, and a triac powers the motor with the necessary polarity of half-wave pulses from the 13.5V-ac input.
