The working principle and energy conversion process of electromagnetic relays

2024-09-11 source:This site clicks:72

Working principle: the coil generates electromagnetic force through the current to attract the armature, the armature drives the moving contact to close with the normally open static contact, when the coil removes the current to make the electromagnetic force disappear, the moving contact returns to the initial position under the action of mechanical force.


Energy conversion process: from electrical energy to magnetic energy, magnetic energy is converted into mechanical energy, and mechanical energy drives the contact to be connected and disconnected, so that the controlled circuit gains and loses electrical energy.
