Revolving magnet coil type and fixed magnet coil type

One kind of automotive air conditioning magnetic clutch:

including drives the shifting plate, the belt pulley, the coil; The coil assembly in compressor's end cover surface, the belt pulley and compressor's end cover detachable coordination, drives the shifting plate and compressor's main axle coaxial close fit, the belt pulley and engine driving pulley constitution transmission, drives between the shifting plate and the belt pulley for the axial play coordination, drives the shifting plate including the concentric gap establishment magnetism sucker, between magnetism sucker through the reed close fit is a whole.

this model utility will solve the existing technical existence to cause magnetism to short-circuit, causes coupling's transmission torque to drop, the reliability reduced question. Had eliminated magnetism short circuit, enhanced the transmission torque, increased the reliable merit.

is very simple, if has the electricity to the meeting and parting coil, the coil does not have the magnetic force, the coupling not to work, that coil has the question, should replace.

if the electric circuit does not have the question, the coil has magnetic force, whether might as well considers the coupling and belt pulley's gap meet standards.

the actually air conditioning compressor's magnetic clutch's principle of work and ordinary is the same with the electric appliance, similarly must satisfy two conditions, a negative line had the electricity to be good.

the voltage or the electric current are excessively high can cause the damage. Or the magnet coil has the opening or the short pass can damage
