AC motor control circuits - ibiblio
www.ibiblio.orgA very common form of latch circuit is the simple ”start-stop” relay circuit used for motor controls, whereby a pair of momentary-contact pushbutton switches control the operation of an electric motor. In this particular case, I show a low-voltage control circuit and a 3-phase, higher voltage motor: L1 L2 M1 M1 Start Stop M1 motor To 3 ...
Understanding Electric Motor Nameplates
www.egr.msu.eduActual circuit voltages may be as high as 125 and 250. Having a circuit voltage a little higher than the motor voltage is usually not a problem. There are some motor and circuit voltage combinations which should be avoided. A motor nameplate with 200, 208, or 200-208 volts should not be operated on a 240 volts circuit unless specifically stated by
