The rotor portion of the clutch becomes magnetized and sets up a magnetic loop that attracts the armature. The armature is pulled against the rotor and a frictional force is generated at contact. Within a relatively short time, the load is accelerated to match the speed of the rotor, thereby engaging the armature and the output hub of the clutch.
Based upon the size of the clutch or brake, the speed and the inertia, wear rates will differ. For example, a machine that was running at 500 rpm with a clutch and is now sped up to 1000 rpm would have its wear rate significantly increased because the amount of energy required to start the same amount of inertia is a lot higher at the higher speed.
By disengaging the clutch, the engine speed (RPM) is no longer determined by the speed of the driven wheels. Another example of clutch usage is in electric drills. [2] The clutch's input shaft is driven by a motor and the output shaft is connected to the drill bit (via several intermediate components). The clutch allows the drill bit to either ...
typical cable glands The parts of a CW type Steel Wire Armour cable gland. Shrouded cable glands going into a flow meter. Split cable gland KVT for routing pre-terminated cables. A cable gland (more often known in the U.S. as a cord grip, cable strain relief, cable connector or cable fitting) is a device designed to attach and secure the end of ...
When the engine reaches a certain speed, the clutch activates, working somewhat like a continuously variable transmission. As the load increases, the speed drops, disengaging the clutch, letting the speed rise again, and reengaging the clutch. If tuned properly, the clutch will tend to keep the speed at or near the torque peak of the engine.
Underbone and miniature motorcycles often have a three to five-speed foot-shift lever, but the clutch is automatic (usually a centrifugal clutch). This type of clutchless (no manual clutch) transmission still must have the gears shifted manually by the rider, and the system is commonly known as a semi-automatic transmission .
Clutch control refers to the act of controlling the speed of a vehicle with a manual transmission by partially engaging the clutch plate, using the clutch pedal instead of (or in conjunction with) the accelerator pedal. The purpose of a clutch is in part to allow such control; in particular, a clutch provides transfer of torque between shafts ...
