Abstract
The utility model discloses an anti-slip magnetic steel fixing structure, comprising a shaft and a magnetic steel mounted on the shaft, wherein the shaft is provided with at least one plane A, and the magnetic steel is provided with a plane B matched with the plane A. The anti-slip magnetic steel fixing structure enables the shaft and the magnetic steel to be milled to be flat, thereby increasing the constraint force in the circumferential direction of the magnetic steel and effectively preventing the magnetic steel from slipping in the circumferential direction; is simple in structure and process, wherein the process only comprises the step of milling the shaft and the magnetic steel to be flat; and is convenient for production and processing, and obvious in anti-slip effect, can better satisfy the system use demand, and can be widely popularized in and applied to the field of the brushless motor magnetic steel fixing technology.
Description
Technical field
The utility model relates to a kind of brushless electric motor rotor magnet steel holding structure, especially relates to a kind of anti-slip magnetic steel fixed structure.
Background technology
Though brushless electric machine is short at the development time of China, but along with the increasingly mature of technology obtained fast development with improving.Be used widely in a plurality of fields such as model plane, medicine equipment, household electrical appliance, electric motor cars.At present, brushless electric machine is just entering the every aspect in model field, and is again to electric model airplane, ubiquitous from electrical remote control vehicle to the electric remote control ship.On structure, brushless electric machine and brush motor have similarity, and rotor and stator are also arranged, and only with the inverted configuration of brush motor, the rotor of brush motor is that coil windings links to each other with power output shaft, and stator is permanent magnetic steel; And the rotor of brushless electric machine is permanent magnetic steel, links to each other with output shaft together with shell, and stator is winding coil, has removed brush motor and has been used for the commutating brush of checker electromagnetic field, therefore be referred to as brushless electric machine.As shown in Figure 1, traditional brushless electric machine adopts inner rotor core usually, magnet steel 2 directly is bonded on the axle 1, adopt this magnetic steel fixed structure, motor is in high speed, frequent rotating use procedure, and the glue between magnet steel 2 and the axle 1 easily lost efficacy, and caused magnet steel to skid, the motor performance sudden change, the system that affects uses.
The utility model content
For addressing the above problem, the utility model provides a kind of anti-slip magnetic steel fixed structure, produces the problem of skidding thereby solved magnet steel in high speed, frequent rotating use procedure.
The purpose of this utility model is achieved by following technical solution.
A kind of anti-slip magnetic steel fixed structure comprises axle and is sleeved on magnet steel on the axle that be provided with at least a plane A on the described axle, magnet steel is provided with the plane B that is complementary with plane A.
Described axle is provided with two plane A, and two positions of plane A on axle are relative, make axle form flat-shaped structure.
Be respectively equipped with two plane B that are complementary with two plane A on the described magnet steel.
The beneficial effects of the utility model are:
The utility model is flat by milling at axle and magnet steel, has increased the constraint of magnet steel circumferencial direction, prevents that effectively magnet steel from skidding at circumferencial direction.Structure, technique are simple, only need milling flat getting final product on axle and the magnet steel, be convenient to production and processing, and the anti-slip successful has satisfied system's instructions for use better, can be in brushless electric machine magnet steel technique for fixing field wide popularization and application.
Description of drawings
Fig. 1 is traditional magnetic steel fixed structure schematic diagram;
Fig. 2 is the utility model magnetic steel fixed structure schematic diagram;
Fig. 3 is the utility model perspective view.
Among the figure: 1-axle, 2-magnet steel.
Embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but that claimed scope is not limited to is described.
Such as Fig. 2, shown in Figure 3, a kind of anti-slip magnetic steel fixed structure comprises axle 1 and is sleeved on magnet steel 2 on the axle 1 that be provided with at least a plane A on the described axle 1, magnet steel 2 is provided with the plane B that is complementary with plane A.
Described axle 1 is provided with two plane A, and two positions of plane A on axle 1 are relative, makes axle 1 form flat-shaped structure.
Be respectively equipped with two plane B that are complementary with two plane A on the described magnet steel 2.
Adopt technique scheme, flat by milling at axle 1 and magnet steel 2, increased the constraint of magnet steel circumferencial direction, prevent that effectively magnet steel 2 from skidding at circumferencial direction.By shop test, custom system test, this magnetic steel fixed structure has all satisfied instructions for use well, and magnet steel 2 anti-slip structure successfuls can be in brushless electric machine magnet steel technique for fixing field wide popularization and application.
