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

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 this alternative power control wiring diagram of controlling a three phase motor from more than two places) .
We may connect;
Start push buttons in Parallel and,
Stop push buttons in Series,
to 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)

  1. please explain circuit diagram<br />

  2. Dear Wasim Khan,
    Appreciated your effort. Please add fuse failure contact and Auto/Man switch also to complete the control circuit. The motor will not be protected from single phasing, if there is no fuse failure contact in control circuit.
