Damped rotation type material level switch driving combination with Hall effect

Abstract

The invention relates to a damped rotation type material level switch driving combination with a Hall effect. The Hall motor module of the damped rotation type material level switch driving combination is arranged in an external shell seat, and comprises a coil stator group, a magnet rotor group, a motor shell seat, a control circuit board and a Hall effect detector. The coil stator group is connected with the control circuit board through wires. The magnet rotor group is arranged in the motor shell base and surrounds the coil stator group, and the Hall effect detector is arranged on the control circuit board and corresponds to the position of the magnet rotor group. The driving shaft group is combined with the motor shell base and rotates along with the magnet rotor group. The reduction gear module is driven by the driving shaft and is transmitted to the rotation stopping assembly. The Hall effect detector is used for replacing a traditional contact type armature and is applied to the driving combination of the damped rotation type material level switch, so that the material level switch is longer in service life and better in safety, more materials are saved, and the purposes of being light, thin, short and small are achieved.

Description

technical field [0001] The invention relates to a level sensor, in particular to a rotary resistance type level switch. Background technique [0002] The conventional anti-rotary level switch uses a motor drive to transmit power to the blades through the drive shaft. Furthermore, the anti-rotary level switch is fixed on the storage bin when installed. When the blade does not touch the material, the motor runs and drives the driving device to run; when the blade touches the material to generate resistance, the motor will reverse and touch the power-off switch. , so that the motor and the driving device stop running, so as to achieve the function of detecting the storage state of the material in the storage bin. [0003] Furthermore, the driving device of the traditional DC resistance rotary level switch mostly uses an armature type small DC motor, which supplies power to the magnetic pole coil of the rotor, so that the magnetic polarity of the rotor and the external fixed pe...

Problems solved by technology

The output of the rotor pole coil of the armature DC motor and the armature must be in contact friction, so after a long time of use, it will cause wear and tear and fail, shortening the service life
