Magnetic Starter(DOL)the motor, i.e., a magnetic switch is utilized to control the starting and stopping of the motor (or motors). Magnetic switches play a key role here by controlling the on-off of the circuit according to changes in the external magnetic field, thus realizing the control of the motor.

The operating principle of a magnetic switch starter motor is mainly based on the influence of a magnetic field and the working principle of a DC motor. When an external magnetic field comes close to a magnetic switch, it triggers a magnetic sensing element (e.g., a reed) inside the switch, causing it to close or break contacts, thus controlling the opening and closing of the circuit. Once the circuit is closed, current flows through the motor, causing it to start rotating. DC motors, on the other hand, work on the principle that an energized conductor moves in a magnetic field by the action of an electromagnetic force.
Magnetic switch: usually consists of a magnetic sensing element and a trigger device, used to detect external magnetic fields and control the on/off of a circuit.
Electric motor: A device that converts electrical energy into mechanical energy and drives various devices through rotation.
Control circuit: Used to receive external signals and control the working status of magnetic switch and motor according to the signals.
