1 Basic Principles of

in motor control circuits and how they relate to the symbols used in ladder diagrams and wiring diagrams. For example, the start pushbutton we mentioned earlier has wires run to the device that contains the set of con-tacts M in Figure 1–4, and to contact points 2 and 3 in Figure 1–6. Figure 1–7 Figure 1–8

Wiring diagrams. Wiring diagrams show the connections to the controller. Wiring diagrams, sometimes called “main” or “construction” diagrams, show the actual connection points for the wires to the components and terminals of the controller. Basic wiring for motor control – Technical data

The control circuit is separate from the motor circuit. The control circuit may not be at the same voltage as the power circuit. When the voltage of the control and power circuits is the same, it is referred to as Common Control. If the volt-ages are different, it is called Separate Control. Figure 4. Typical Starter Wiring Diagram — Three-Phase

Electric Motor Controls, G. Rockis, 2001 Wiring Diagrams Wiring (connection) diagram – a diagram that shows the connection of an installation or its component devices or parts. Wiring diagrams show, as closely as possible, the actual location of each component in a circuit, including the control circuit and the power circuit.

Figure 1 – A Motor Controller Schematic. The contacts, M, will be controlled by the coil, M.The output of the motor starter goes to a three phase AC motor. Power is supplied by connecting a step down transformer to the control electronics by connecting to phases L2 and L3. The lower voltage is then used to supply power to the left and right rails of the ladder below.
