When current passes through the electromagnet, a magnetic field is produced, which attracts the moving core of the contactor. The electromagnet coil draws more current initially, until its inductance increases when the metal core enters the coil. The moving contact is propelled by the moving core; the force developed by the electromagnet holds the moving and fixed contacts together. When the contactor coil is de-energized, gravity or a spring returns the electromagnet … Web21 sep. 2011 · Coils are designed with a certain effective wire length and reactance.

WebThe working principle of the magnetic contactor is that the main contact is closed due to the coil being energized, and the main contact is disconnected due to the de-energization of the coil. The control circuit is composed of electromagnetic and spring system. The current through the coil activates the magnetism, and the two magnetism ... WebThe reading should be the actual voltage supply. If the contactor coil doesn’t close, even if the voltage is correct, you should shut off the energy flow. Rest the volt ohmmeter back to ohms. Touch every lead which leads to the coil connector. Ensure the multimeter reads between 10-100 ohms. If it doesn’t, your coil should be changed.
