Abstract
The invention discloses a feedback element installed on a motor rotary shaft. The feedback element comprises the motor rotary shaft, a Hall rotor and a Hall element plate, wherein the Hall rotor and the Hall element plate are of disc-shaped structures. The Hall rotor is arranged at the top of the motor rotary shaft and is fixed through first screws. The Hall element plate is fixed with a motor back end cover arranged on the outer side of the motor rotary shaft through second screws. The Hall rotor consists of a Hall rotor rotating disc and Hall rotor magnetic steel, wherein the Hall rotor magnetic steel is evenly and symmetrically arranged on the Hall rotor rotating disc. The Hall element plate comprises a circuit board and Hall elements, wherein the Hall elements are annularly arranged on the circuit board in an array mode. A magnetic field of the feedback element installed on a motor rotary shaft is an axial magnetic field, a shape of the whole feedback element is a flat disc, axial length of a motor is greatly shortened, and the feedback element has high anti-interference performance, is compact in structure and meets the demands of electric vehicles well.
Description
Technical field
The present invention relates to a kind of feedback element of electric automobile magneto, relate 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.
