What is a magnetic clutch?
Magnetic clutch is a device that allows connection and disconnection between two coaxial shafts. In terms of operation, the magnetic clutch works almost as well as a conventional clutch and both items serve about the same function in most machines. The engine or engine is controlled by a flywheel and clutch, which is made of a material with a high coefficient of friction, is located on its peak. The difference between magnetic couplings and standard models is how the pressure plate controls the engagement and release of the clutch plate with a flywheel. In normal couplings, the membrane spring is used to connect the clutch and inertia, while the magnetic couplings are used electromagnetic fields. a rotor that corresponds to a flywheel in a conventional clutch; fitting that corresponds to the clutch plate; And a hub, also known as the output. When the current through the coil passes, and genes N electromagnetic fields, whose strength must be strong enough to overcome the power of the springs that separate the rotor and the pen. This electromagnetThe field attracts the armature into contact with the rotor, causing the movement of the anchor. The hub is connected to the fitting, which is connected to the second shaft.
The functionality and power of the magnetic clutch depends on different factors and to prevent the coil overheating, a constant voltage is necessary. The initial effects of friction between the fittings and the rotor are a problem that is solved by the tutor booth to wear the surface and make it as smoothed as possible. To achieve a faster response time, a technique known as excessive excitation is implemented; This is where the coil briefly receives voltage several times higher than the standard rating. For example, the use of a 15 times the normal coil voltage provides a response time that is three times faster than the standard response time.
A typical car car uses conventional clutches to move gears and transmission torque from the engine to the crankshaft.However, most cars with air conditioning systems use a magnetic clutch to allow the air compressor to draw energy from the engine when the air conditioning is on from the instrument panel. The same type of technology is also widely used in high -performance brake systems. Magnetic couplings are also used in many other pieces of machines that are used daily, from copying machines to grass mowers.
