Abstract

The invention discloses an electromagnetic clutch which belongs to the technical field of mechanical and electrical integration; a coil winding is arranged in a slot plate of the electromagnetic clutch; a pulley and the slot plate are connected through a central shaft; the central shaft and a rotor are tightly matched; both ends of the central shaft are respectively matched with a bearing which is arranged in the pulley and a bearing which is arranged in the slot plate; an armature and the pulley are connected through a leaf spring; a carriage is arranged on one side of the slot plate and is integrally assembled with the slot plate; one side of the carriage which is back to the slot plate is provided with two trays; and two permanent magnet bodies are respectively tabled in each tray with the polarity being opposite. Long arms of the two L-shaped permanent-magnet poles are respectively fitted to the tray and the permanent-magnet poles and are fastened by screws, short arms of L-shaped permanent-magnet poles face to the direction of the armature, and the two permanent magnets are laid in the shape of figure eight. The size of the electromagnetic clutch provided by the invention is reduced, so that the clutch manufacturing cost and the power consumption are reduced, the structure is simple and reliable, and the braking effect is significantly improved.

Description

technical field [0001] The invention relates to an electromagnetic clutch and belongs to the technical field of electromechanical integration. Background technique [0002] The working principle of the electromagnetic clutch is as follows: it includes the magnetic shell of the electromagnetic clutch, an electromagnetic coil assembled in the magnetic shell, and a driving rotor input by other components that rotate relative to the stator; an armature is connected with the output mechanism, rotates relative to the rotor and able to control. When the coil is energized to generate a magnetic field, the magnetic field lines pass through the stator housing and the rotor, and pass through the air gap between the rotor and the armature, attracting the armature to engage with the rotor, and driving the output mechanism connected to the armature to rotate in unison with the input mechanism. When the coil is de-energized, the leaf spring pulls the armature to disengage from the rotor t...
