Motor Control Schematic Diagram

Schematics and wiring diagrams are the written language of control circuits.

Motor control schematic diagram. They are an ideal means for troubleshooting a circuit. The above diagram shows how to connect the l298 ic to control two motors. Motor 3ct to 120 v separate control ot is a switch that opens when an overtemperature condition exists type mfo. Schematic diagrams do not always show both control and motor connections.

Control circuit connected to l1 l2 l1 l3 l1 l2 for reversing interchange lines. Line diagrams also called schematic or elementary diagrams show the circuits which form the basic operation of the controller. An alternative to the conventional schematic diagram in ac power control systems is the ladder diagram. Many schematic diagrams show only the control circuit.

They do not indicate the physical relationships of the various components in the controller. Three phase motor connection schematic power and control wiring installation diagrams. Typical controller markings typical elementary diagram table 4 control and power connections for across the line starters 600 v or less. Schematics wiring diagrams is part five of the motor controls eight part training series.

Line diagrams show circuits of the operation of the controller. Three phase motor connection star delta without timer power control diagrams. In this convention the hot and neutral power conductors are drawn as vertical lines near the edges of the page with all loads and switch contacts drawn between those lines like rungs on a ladder. Motor control wiring diagram pdf wiring diagram is a simplified usual pictorial representation of an electrical circuit it shows the components of the circuit as simplified shapes and the facility and signal associates with the devices.

Following is the schematic diagram of the dc motor interface to arduino uno board. There are three input pins for each motor input1 in1 input2 in2 and enable1 en1 for motor1 and input3 input4 and enable2 for motor2. Motor contactor or starter coils are typically designated by the letter m in ladder logic diagrams. The interlock contacts installed in the previous section s motor control circuit work fine as discussed in previous article but the motor will run only as long as each pushbutton switch is held down.

Notice in this schematic that there is no complete circuit to m motor starter coil because of the open start push button and open m auxiliary contacts. Before a technician can become proficient in troubleshooting control circuits he must learn how to read and interpret schematic and wiring diagrams.
