Product Description

The electromagnetic clutch is a friction clutch in which a pressing force is generated by an electromagnetic force. Because it can realize long-distance control, small control energy, easy to realize machine tool automation, fast action, simple structure, and has been widely used.

There are two types of electromagnetic clutches: fixed coil type and rotating coil type. The former electromagnetic coil is fixed on the compressor housing and does not rotate, while the latter electromagnetic coil is connected to the belt reel to rotate. (1) The fixed coil clutch electromagnetic coil is installed on the compressor end cover and does not rotate. The rotor is held on the electromagnetic coil by bearings and circlips. The outside of the rotor is the belt reel. The armature (clutch plate) is attached to the end of the compressor crankshaft. The fixed coil electromagnetic clutch is mainly composed of a pulley, an electromagnetic coil, a pressure plate, and a shaft hub assembly. One end of the electromagnetic coil is grounded, and the other end is connected to the power supply through an air conditioning relay. When the air conditioner switch is turned on, the air conditioning relay is turned on, and the electromagnetic coil of the compressor is energized, generating a strong magnetic field, so that the electromagnetic clutch driven disc of the compressor and the freely rotating pulley are attracted, thereby driving the compressor main shaft to rotate. The refrigeration system works. When the air conditioner relay is de-energized, the current of the electromagnetic clutch coil is cut off, and the magnetic field disappears. At this time, the driven plate and the pulley are separated by the action of the spring to stop the compressor. (2) The working principle of the rotating coil clutch is the same as that of the fixed coil clutch, but the position of the electromagnetic coil is different. In the rotating coil type structure, the electromagnetic coil is a part of the rotor and rotates with the rotor. An electric current flows through the brush mounted on the compressor to the electromagnetic coil to establish a magnetic field. The magnetic field brings the armature into contact with the rotor, and the rotation of the entire electromagnetic clutch device composed of the armature, rotor and coil drives the rotation of the compressor. These two types of electromagnetic clutches have several flow collecting grooves on the armature and the rotor to facilitate the collection of magnetic fields and increase the attraction of the two.
