Connection Method Of DC Coil Contactor

May 30, 2018

1. Contactor is only with main power supply and coil power supply, connect the coil power supply negative pole with the coil positive pole, and connect the switch to the other end, the main line is connected with the motor.

2. DC motor is driven by direct current electric motors. The working principle of DC motor: when the coil is energized, the rotor generates a magnetic field around it, the left side of the rotor is pushed away from the left magnet and is attracted to the right side, then resulting in rotation. The rotor relies on inertia to continue to rotate. When the rotor runs to a horizontal position, the current converter reverses the current direction of the coil, and the magnetic field generated by the coil reverses simultaneously, making the process repeatable.
