Abstract
The utility model relates to a feedback element disposed on a motor rotation shaft. The feedback element comprises a motor rotation shaft, Hall rotors and Hall element boards, wherein the Hall rotors and the Hall element boards are all configured to be in disc-shaped structures; each Hall rotor is disposed at the top of the motor rotation shaft and is fixed by a first screw; and each Hall element board is fixed with a motor rear end cap disposed on an outer side of the motor rotation shaft through a second screw. Each Hall rotor consists of a Hall rotor rotation disc and Hall rotor magnetic steel, wherein the Hall rotor magnetic steel is uniformly and symmetrically disposed on the Hall rotor rotation disc. Each hall element board includes a circuit board and Hall elements, wherein the Hall elements are annularly arrayed on the circuit board. According to the feedback element disposed on the motor rotation shaft, the magnetic field is an axial magnetic field; the shape of the feedback element is a flat disc; and accordingly the axial length of the motor is substantially shortened, and the feedback element is high in anti-interference resistance and compact in structure, thereby satisfying demands of electric vehicles very well.
Description
Technical field
The utility model relates to a kind of feedback element of electric automobile magneto, relates in particular to a kind of feedback element that is installed on the machine shaft.
Background technology
Electric automobile magneto feedback element generally is installed in the motor tail end of casing outside, its anti-interference of this mounting means is more intense, but because the magnetic field of the feedback element of this mounting means is radial magnetic field, the shape that has caused whole feedback element is cylindric, axial length is longer, can not satisfy the needs of the compact appearance on the electric automobile.
