AI Technical Summary
Technical Problem
When the traditional electromagnetic clutch is working, the noise is high due to the high impact noise between the armature and the rotor, which affects the user's comfort.
Method used
By installing a tower-shaped compression spring between the flange and the armature, the traditional wave spring is eliminated, ensuring that the armature and the rotor always remain clear and noise is reduced.
Benefits of technology
In normal operation and clutch states, there is no gap-coordination between the armature and the rotor, which significantly reduces the noise of the electromagnetic clutch and improves the comfort of users using the product.

Abstract
The low-noise electromagnetic clutch comprises an output shaft, a flange, an armature, a rotor, a magnet yoke, a coil, a bearing and a compressed spring, the output shaft sequentially penetrates through central through holes of the flange, the armature, the rotor and the magnet yoke, the output shaft is fixedly connected with the rotor, the output shaft is connected with the magnet yoke through the bearing, the coil is installed in the magnet yoke, and the compressed spring is arranged in the coil. The armature is installed on the flange and located between the flange and the rotor, and the compression spring is installed between the flange and the armature and generates elastic force for enabling the armature to be close to the rotor on the armature. According to the utility model, the armature and the rotor are always kept in a gapless state under the action of the pressure spring, and no impact noise exists before and after the clutch action; although friction noise generated by relative rotation exists between the armature and the rotor in the clutch state, the friction noise is very small and can not be heard by a user basically in practical application, so that the working noise of the electromagnetic clutch is remarkably reduced on the whole, and the product using comfort of the user is improved.
