[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a precisely controlled dynamic load adjustment electromagnetic clutch, which has the following beneficial effects:

[0016] 1. The precisely controlled dynamic load adjustment electromagnetic clutch can stably improve the stability of the gear shaft. When the shaft rotates, it drives the clutch base, the speed regulating disc and the armature to rotate. At this time, the coil in the coil 1 is energized to generate magnetic flux, forming a magnetic force to attract the armature, so that the armature squeezes the multiple groups of friction plates on the right end of the armature. The friction force of the friction plate is relatively large, so that the armature can perform friction transmission with the friction plate, so that the friction plate drives the outer sleeve connected to the friction plate to rotate. When the magnetic flux increases again, the magnetic force formed continues to pull the armature to move toward the clutch base, so that there is no gap between the clutch base, the shaft and the speed regulating disc, and the clutch speed and torque are adjusted.

[0017] 2. The precisely controlled dynamic load adjustment electromagnetic clutch can precisely control and adjust the dynamic load. When coil two is turned on, the magnetic flux generated by coil two is opposite to or the same as that of coil one to adjust the magnetic force generated by coil one to achieve stable and precise control.
