Flowchart schematic diagram for the Control Circuit of a Forward Reverse Star Delta or Wye Delta Electric Motor Controller - A how to learn skills training guide for electric motor controller

To help facilitate for a better understanding and further learning and training on the concept of the forward reverse star delta (or wye delta) control (ckt) circuit covered in our previous article, a reversible star delta starter control circuit diagram accompanied with a flowchart diagram is presented below as a follow up learning guide which shows a schematic representation of the sequence of operation for the starting and stopping and running operation of a reversible star delta or wye delta electric motor control circuit in order to provide a visual aid to help diagrammatically visualize how the control circuit flows.
