Abstract
The invention relates to a speed regulator, and the speed regulator comprises a housing. The housing is provided with a limiting pin and a limiting block. One end of a rocking arm is connected to the housing through a rotating shaft, and can swing around the rotating shaft. One end of a tension spring is hung on the rocking arm, and the other end of the tension spring is hung on the housing. The rocking arm is provided with a magnetic steel, and the housing is provided with a Hall plate. The position of the Hall plate is adjusted, so as to adjust the relative position of a Hall element and the magnetic steel and adjust a voltage to the biggest value. The speed regulator solves a problem that the Hall element and the magnetic steel cannot be adjusted during assembly. Compared with a current speed regulator structure, the speed regulator can precisely adjust the maximum output voltage through adjusting the relative position of the Hall element and the magnetic steel during the installation of the Hall plate, so as to meet our demands.
