Starting & Stopping of 3-Phase Motor from more than One Place Power & Control diagrams

Whenever we need to start and stop the motor from more than one point, then we may expand it through push buttons in the motor control circuit ( for example, You may use re than two places) this alternative power control wiring diagram of controlling a three phase motor from mo .

We may connect;

Start push buttons in Parallel and,

Stop push buttons in Series,

t o control ON / OFF operation of the motor from more than one place.

Whenever we need to provide emergency stop to the 3-Phase Motor, apart the motor Start and Stop push buttons, we may use many more (as needed) Stop push buttons (Use Start Push buttons in parallel and Stop push buttons in series ) .

The main advantage of using the Contactor , we can control i.e. Start and Stop the motor from any location

Suppose, you have to Control the Motor ON/OFF operation from more than two or three places, for this propose, you may use the following simple control circuit.

Abbreviations:

L1 , L2, L3 = Red, Yellow, Blue ( 3 Phase Lines)

N = Neutral

O/L = Over Load Relay

NO = Normally Open

K1 = Contactor (Contactor coil)

K1/NO = Contactor Holding Coil (Normally Open)
