Abstract
The utility model discloses an anti-vibration brushless motor tracking rotor structure which is mainly composed of a printed board, a Hall, a tracking magnetic steel and a tracking rotor bracket, wherein the Hall is installed on the printed board, the tracking magnetic steel is installed in a groove of the tracking rotor bracket, and the outer circumference of the tracking rotor bracket is provided with a sheath wrapping the tracking magnetic steel. The sheath is additionally arranged on the outer circumference of the tracking rotor bracket to wrap the magnetic steel so that the magnetic steel can be ensured not to fly off due to large vibration, and a flange at the outer side of the sheath can ensure that the sheath cannot slip off. Meanwhile, the holding strength of the magnet steel can be effectively ensured due to the adoption of a mechanical holding structure.
Description
Technical field
The utility model relates to Hall feedback position signal formula brushless electric machine and follows the tracks of the rotor structure technical field, especially relates to a kind of anti-vibration brushless electric machine and follows the tracks of rotor structure, is specially adapted to the big occasion of vibration level.
Background technology
Brushless electric machine is a kind of special direct current machine, and the method that its adopts built-in sensors to add electronic commutator is carried out electronic commutation, and brushless electric machine mainly is in order to eliminate the wearing and tearing of brush, and the noise that produces of brush contact.Brushless electric machine is used in control usually and requires than higher, and on the higher equipment of rotating ratio, as model plane, precision instrumentation etc. are strict to motor speed control, and rotating speed reaches very high equipment vendor.Existing small-sized brushless electric machine structure compactness, as shown in Figure 1, mainly by printed board 4, be installed in the Hall 3 in the printed board 4 and follow the tracks of rotor structure and form, it follows the tracks of rotor structure is rotor magnetic steel 2 directly to be sticked with glue be connected on the rotor field spider 1, because volume is less, magnet thickness is generally 0.75～1.5mm, radial height is 1.5～2mm, the magnet steel bond area is very little, cause adhesion strength enough not big, therefore motor is under the big situation of vibration level, and magnet steel is easy to fly out, and causes motor to sweep hall.
The utility model content
For addressing the above problem, the utility model provides a kind of anti-vibration brushless electric machine to follow the tracks of rotor structure, thereby has guaranteed that magnet steel can effectively not guarantee magnet steel fixing intensity simultaneously because vibration level flies out greatly.
The purpose of this utility model is achieved by following technical solution.
A kind of anti-vibration brushless electric machine is followed the tracks of rotor structure, mainly formed by printed board, Hall, tracking magnet steel and tracking rotor field spider, described Hall is installed in the printed board, follow the tracks of magnet steel and be installed in the groove of following the tracks of rotor field spider, described tracking rotor field spider excircle is provided with and will follows the tracks of the sheath that magnet steel encases.
The described sheath outside is provided with flange, the cannelure that inside is and tracking rotor field spider excircle is complementary.
Described cannelure medial angle is and follows the tracks of the arc surface that rotor field spider is complementary.
Described sheath and the gap of following the tracks of between the rotor field spider adopt glue to fill.
The beneficial effects of the utility model are:
Compared with prior art, the utility model encases magnet steel by sheath by once established sheath on tracking rotor cylindrical, guarantees that magnet steel can not fly out because vibrating greatly, can landing by the flange assurance sheath in the sheath outside.The utility model can effectively guarantee magnet steel fixing intensity by adopting mechanically retained structure simultaneously.

Fig. 3 is 1/2 perspective view of the utility model sheath.
Among the figure: 1-rotor field spider, 2-follow the tracks of magnet steel, 3-Hall, 4-printed board, 5-tracking rotor field spider, 6-sheath, 7-flange, 8-arc surface, 9-cannelure.
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.
As Fig. 2, shown in Figure 3, a kind of anti-vibration brushless electric machine is followed the tracks of rotor structure, mainly formed by printed board 4, Hall 3, tracking magnet steel 2 and tracking rotor field spider 5, described Hall 3 is installed in the printed board 4, follow the tracks of magnet steel 2 and be installed in the groove of following the tracks of rotor field spider 5, described tracking rotor field spider 5 excircles are provided with and will follow the tracks of the sheath 6 that magnet steel 2 encases.
Described sheath 2 outsides are provided with flange 7, the cannelure 9 that inside is and tracking rotor field spider 5 excircles are complementary.
Described cannelure 9 medial angles are and follow the tracks of the arc surface 8 that rotor field spider 5 is complementary.
Described sheath 6 and the gap of following the tracks of between the rotor field spider 5 adopt glue to fill.
Operation principle of the present utility model is:
Pass to controller by hall signal, controller is powered to motor coil by the motor phase line, the motor rotation, rotor magnetic steel and coil rotate, the position signalling that hall sensing makes new advances, controller changes sense of current power supply for again motor coil again, and motor continues rotation, thereby realizes the commutation of brushless electric machine electronics.
