A how to guide for the Control Circuit of a Forward Reverse Electric Motor Controller

Controlling the AC induction motor's rotation either in the forward or reverse direction with the push of a button is made possible by the forward reverse control circuit. The electrical diagram below illustrates the operational sequence of the forward reverse control system specific for the command of the forward reverse power circuit used in every electrical industry involving industrial process automation control technology.

A how to guide for the Power Circuit of a Forward Reverse Electric Motor Controller

There are certain applications that requires forward and reverse direction of motor rotation, such as a conveyor system, or perhaps the opening and closing of valves. Another example is with overhead cranes which would also require a hoist up and down function, traverse forward and backward, and a left and right traveling function. Such application would most certainly make use of a forward and reverse motor control which is intended to achieve clockwise and counter clockwise motor rotational direction.

A how to guide for the Control Circuit of a Direct On Line DOL Electric Motor Controller

As mentioned in the previous article, the Direct On Line (DOL) control circuit is an electrical control system which is intended for controlling the DOL power circuit. The electrical schematic diagram below illustrates the operational system of the DOL control circuit used in every electrical industry involving industrial process automation control technology.

A how to guide for the Power Circuit of a 3 Phase Direct On Line DOL Electric Motor Controller

In the simplest method of motor operation for small size AC induction motors, the Direct On Line (DOL) motor controller is most popular in terms of simplicity and control device availability. DOL motor controller is suitable for application with small capacity motors which does not cause too much high inrush current that can pull down the supply voltage of the available power source from the electricity supply grid.

How to Learn Electric Motor Control – A Basic Motor Controller Guide for Electrical Motor Controls used in every electrical industry involving industrial process automation control technology

Have you ever wondered what makes an electric motor work, what special types of control system is incorporated to its circuit to make it run for specific applications?
