AI Technical Summary

Problems solved by technology

[0003] The traditional motor Hall position sensor has a power supply wire, a ground wire, and three Hall output wires. If the wires are too easy to connect incorrectly, the motor will not work or the motor will be burned, which greatly affects the normal use of the motor.

Abstract

The invention relates to the technical field of motor rotor position detection equipment and discloses a Hall motor rotor position acquisition device, which comprises a motor, a detection module and acontrol module. A rotating shaft is fixedly connected in the motor. The outer wall of the rotating shaft is fixedly connected with a rotor and a magnetic ring. A mounting ring is fixedly connected tothe inner wall of the motor. The inner wall of the mounting ring is fixedly connected with a plurality of Hall sensors corresponding to the magnetic ring. The detection module includes a detecting unit and a sensing unit for detecting the position of the rotor. The control module includes a main board, three signal conversion units, and a signal amplification unit. The Hall motor rotor position acquisition device only needs one or two connecting wires, greatly saves the cost of changing three wires into one wire especially for an electric rotating tool product which needs a long connecting wire, and has obvious advantages in the product requiring a large number of wires.

Description

technical field [0001] The invention relates to the technical field of motor rotor position detection equipment, in particular to a Hall motor rotor position acquisition device. Background technique [0002] Hall motors generally refer to all machines that can convert mechanical energy into electrical energy and electrical energy into mechanical energy. Specifically refers to generators, electric energy machines, and motors. According to the classification of working power sources, according to the different working power sources of motors, they can be divided into DC motors and AC motors. Among them, AC motors are also divided into single-phase motors and three-phase motors. According to the structure and working principle, motors can be divided into DC motors, asynchronous motors and synchronous motors according to their structure and working principles. [0003] The traditional motor Hall position sensor has a power supply wire, a ground wire, and three Hall output wires...
