Calculate electric motor ... Motor contactor (or “starter”) coils are typically designated by the letter “M” in ladder logic diagrams. Continuous motor operation with a momentary “start” switch is possible if a normally-open “seal-in” contact from the contactor is connected in parallel with the start switch so that once the contactor is energized it maintains power to itself and keeps itself “latched” on. Typically, the contactor will be controlled by separate start and stop buttons, and an auxiliary contact on the contactor is used, across the start button, as a hold in contact. I.e. the contactor is electrically latched closed while the motor is operating. Principle of Direct On Line Starter (DOL) Wiring Diagrams . ... 1998 Square D All Rights Reserved.
