Magnetic Motor Starter Diagram. Magnetic motor starters are essentially heavy duty relays often equipped with heater thermal overloads matched to the motor they start. A 3 pole full voltage magnetic motor starter is made up of the following.
The magnetic motor starter is an electromagnetically operated set of contacts that starts and stops the connected motor load. They are then controlled using a lighter duty low or high voltage circuit auxillary relay contacts and a control station or several stations utilizing lighter duty switches usually momentary sometimes. Figure 1 typical wiring diagram line diagrams show circuits of the operation of the controller line diagrams also called schematic or elementary diagrams show the circuits which form the basic operation of the controller.
Magnetic motor starters are essentially heavy duty relays often equipped with heater thermal overloads matched to the motor they start.
It uses two contactors two auxiliary contact blocks an overload relay a mechanical interlock two normally open start pushbuttons a normally closed stop pushbutton and a power supply with a fuse. Magnetic motor starters are essentially heavy duty relays often equipped with heater thermal overloads matched to the motor they start. Estop wiring diagram on magnetic motor starter source. The primary purpose of a motor starter is to start and stop a motor which it is connected to safely.
