Unit 1 conclusion this unit explained the basic concepts of motor con trols concentrating on how specialized electrical sym bols words and line diagrams are used to convey information about motor control circuits. Really is the best college for practical knowledge base learning. The follow up question of how we may make the motor stop running is a. It only have a main switch for stop start operation and fuse for motor protection this method have disadvantage and not safe to used because as shown circuit diagram below 1.

Basic motor control wiring diagram wiring diagram is a simplified pleasing pictorial representation of an electrical circuit it shows the components of the circuit as simplified shapes and the facility and signal contacts in the company of the devices. Control circuits can be divided into two major types. A two wire control circuit can be a simple switch that makes or breaks connection to a motor figure 18 1. Control circuits can be divided into two major types.

The contact in parallel with the run switch is often referred to as a seal in contact because it seals the momentary condition of the run switch closure after that switch is de actuated. When first motor were introduced for application the common control is only basic manual stop and start circuit diagram. If we wanted to keep the motor running even after the operator takes his or her hand off the control switch es we could change the circuit in a couple of different ways. The interlock contacts installed in the previous section s motor control circuit work fine but the motor will run only as long as each push button switch is held down.

A good example of this type of control is the single phase manual starter shown in figure 3.
