Utility model content
The utility model proposes the external Hall device of a kind of DC brushless electric motor in order to address the above problem, its Stability Analysis of Structures, device compactness, save material, the position of conveniently adjusted Hall, adaptability is good, on motor especially high-speed electric expreess locomotive time, can make motor performance consistency high, vibration resistance, has good practicality.
The utility model solves the technical scheme that its technical problem adopts: the external Hall device of a kind of DC brushless electric motor, comprise three hall integrated packages, for the circular wiring board of hall integrated package is installed, for the circular embedding slot at the electric motor end cap center of being located at of setting-in wiring board; Described hall integrated package is circumferentially distributed in the end face of wiring board, and the sensitive surface of hall integrated package is adhered to downwards on wiring board; The edge of described wiring board is uniform three deep-slotted chip breakers and three location holes circumferentially, and deep-slotted chip breaker and location hole interval arrange, and the length of deep-slotted chip breaker is not less than 1/5 of its residing wiring board girth; The center of described embedding slot is provided with motor axis hole, circumferential uniform three road installing web plates between motor axis hole and embedding slot edge, and on installing web plate, corresponding deep-slotted chip breaker is provided with installing hole respectively.
Center between corresponding two the adjacent positioned holes of described hall integrated package arranges.
The end face of described installing web plate is not less than the thickness of wiring board apart from the distance of embedding slot top mouth.
The beneficial effects of the utility model are: the external Hall device of a kind of DC brushless electric motor, and wiring board is made as circular configuration and embedding slot shape is coincide, convenient installation; The sensitive surface of hall integrated package fits on wiring board and makes it that compactness is installed, and has improved the accuracy of induction; Arranging of deep-slotted chip breaker improved the flexibility that wiring board is installed, and facilitates the position of fine adjustment hall integrated package; The setting party of location hole the location of hall integrated package.This utility model has Stability Analysis of Structures, device is compact, saves the advantage of material.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing 1 is the example structure schematic diagram of the external Hall device of DC brushless electric motor.
Accompanying drawing 2 is embedding slot structural representations of the external Hall device of DC brushless electric motor.
In figure, 1. electric motor end cap, 2. wiring board, 3. hall integrated package, 4. deep-slotted chip breaker, 5. location hole, 6. installing web plate, 7. motor axis hole, 8. embedding slot, 9. installing hole.
Embodiment
In the accompanying drawings, the external Hall device of a kind of DC brushless electric motor, comprises three hall integrated packages 3, for the circular wiring board 2 of hall integrated package 3 is installed, for the circular embedding slot 8 of being located at electric motor end cap 1 center of setting-in wiring board 2; Described hall integrated package 3 is circumferentially distributed in the end face of wiring board 2, and the sensitive surface of hall integrated package 3 is adhered to downwards on wiring board 2; The edge of described wiring board 2 is uniform three deep-slotted chip breakers 4 and three location holes 5 circumferentially, and deep-slotted chip breaker 4 arranges with location hole 5 intervals, and the length of deep-slotted chip breaker 4 is not less than 1/5 of its residing wiring board 2 girths; The center of described embedding slot 8 is provided with motor axis hole 7, circumferential uniform three road installing web plates 6 between motor axis hole 7 and embedding slot 8 edges, and on installing web plate 6, corresponding deep-slotted chip breaker 4 is provided with installing hole 9 respectively.
Center between corresponding two the adjacent positioned holes 5 of described hall integrated package 3 arranges.
The end face of described installing web plate 6 is not less than the thickness of wiring board 2 apart from the distance of embedding slot 8 top mouths.
While installing and using, wiring board 2 is embedded in embedding slot 8, grasp the axis hole at wiring board 2 centers with finger, wiring board 2 is regulated, make the installing hole 9 on the interior installing web plate 6 of deep-slotted chip breaker 4 and embedding slot 8 corresponding, and be screwed.
In the course of work, the rotor of Hall element rotates with the main rotor of motor, because Hall element rotor is the multi-pole magnet-ring of an axial charging, follow the number of poles of the main rotor of motor to equate, therefore hall integrated package 3 detects motor by the rotation that detects Hall element rotor.Owing to there being three to become the equally distributed location hole 5 of 120 degree on wiring board 2, can accurately locate the position of three hall integrated packages 3, three deep-slotted chip breakers 4 that arrange on wiring board 2, position that can accurate adjustment Hall, above design can meet installation and the use of the position transducer (electrical degree 120 is spent) of the three-phase brushless motor that different numbers of poles and groove number coordinate.
