Description
Technical field
The utility model relates to a kind of Hall fixture, relates in particular to a kind of Hall fixed mount, belongs to the technical field that motor is manufactured.
Background technology
As everyone knows, Hall is the element that is used for induction electromotor rotor position on the motor, need during installation Hall is accurately located to guarantee that it accurately detects the position of rotor, the fixed form of Hall is varied at present, generally adopt the lead-out wire of Hall and the mode of wiring board welding are fixed, though fixed form is simple, but can't accurately locate Hall, make Hall can't accurately measure the position of rotor, cause motor stator accurately to commutate, cause the motor operation not steady thus, moment of torsion reduces, and vibration strengthens, and the big spoke degree of electric efficiency descends, temperature rise causes burn-down of electric motor when serious.
" brushless motor Hall structure (CN201252462Y) " discloses a kind of Hall fixed structure as Chinese patent, it comprises Hall and the coil rack of fixing with stator punching, it is characterized in that described coil rack end along the circumferential direction evenly is furnished with the arc plush copper that some intervals are provided with, the location notch of formation and Hall match profiles between the adjacent arc plush copper, described Hall lower end is engaged in the location notch.This device is by the coil rack end at motor location notch to be set to fix Hall, Hall accurately can be located when therefore assembling, improved production efficiency, but this apparatus structure complexity, and the location notch at Hall place is the thermal source district, owing to can produce temperature rise during machine operation, particularly when machine operation during in inefficient district, the speed of heat accumulation is very fast, and performance drift can appear in the Hall that is set directly at the thermal source district, cause the big spoke degree of electric efficiency to descend thus, temperature further raises, and causes related electronic devices to burn when serious.
Summary of the invention
The utility model purpose be to provide a kind of simple in structure, cost is low, installation and convenient maintenance and replacement are quick, and can be with the accurate location and prevent that effectively Hall from crossing cause thermal damage, prolonging the motor Hall fixed mount in useful life of Hall, solve fixed structure complexity, cost height that prior art exists, can't prevent effectively that Hall from crossing cause thermal damage, thereby reduced problem such as motor useful life.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: a kind of Hall fixed mount, comprise wiring board, outer rim at described wiring board is arranged with the circular orientation frame, the inner ring surface of described circular orientation frame is provided with the Hall location notch, end face is provided with annular groove, and described wiring board interlocking is in annular groove.Be arranged with the circular orientation frame by outer rim at wiring board, and fix Hall by the Hall location notch on the circular orientation frame inner ring surface, simple in structure, the Hall location notch can guarantee that Hall accurately locatees, fixed form is simple and reliable, the circular orientation frame is located away from outside the motor heat source region Hall, thereby prevents that Hall from crossing cause thermal damage, has prolonged the useful life of motor; End face at the circular orientation frame is provided with the annular groove fixing circuit board, and fixed form is simple, easy accessibility, has improved production efficiency.
As preferably, described Hall location notch is axial trapezoid-shaped openings groove, and its open end is less than groove bottom.By axial trapezoid-shaped openings groove is set on the inner ring surface of circular orientation frame, make Hall slip into the groove internal fixation from axle head, fixed form is simple and reliable, and open end makes the Hall easy accessibility.
As preferably, described annular groove is located on the surface adjacent with the wiring board lateral surface with the circular orientation frame is coaxial.Annular groove can make wiring board set in the annular groove and the Hall holding position on the circular orientation frame inner ring surface stable with being located on the circular orientation frame, connects reliably, guarantees that motor operates steadily, prolongation motor useful life.
As preferably, on the outer edge surface of described circular orientation frame, be provided with projection, be axially arranged with location hole in described protruding upper edge, described circular orientation frame links to each other with electric motor end cap by location hole.By on the circular orientation frame, be provided with location hole link to each other with electric motor end cap guarantee the circular orientation chord position put stablize constant; even the hall position on the circular orientation frame immobilizes; simple and reliable for structure; by outer edge surface projection is set at the circular orientation frame; and by location hole is set on projection, in light weight, cost is low.
As more preferably, be provided with two location holes on the described circular orientation frame at least, described location hole is uniform on the outer edge surface of circular orientation frame.Link to each other with electric motor end cap by the location hole more than two or two, guarantee to connect reliable.
As preferably, described circular orientation frame is the partiting thermal insulation material.The circular orientation frame of being made by the partiting thermal insulation material can improve Hall and extraneous effect of heat insulation, guarantees that Hall is effectively protected, and prolongs the useful life of motor.
Therefore, a kind of Hall fixed mount of the present utility model has following advantage: be arranged with the circular orientation frame by the outer rim at wiring board and fix Hall, the Hall accurate positioning makes Hall be located away from outside the motor heat source region again, thereby prevent that Hall from crossing cause thermal damage, prolonged the useful life of motor; By on the circular orientation frame, be provided with location hole link to each other with electric motor end cap guarantee the circular orientation chord position put stablize constant, simple and reliable for structure.
