Post 22 is suitable to coordinate with circumferentially positioned hole 420.
The magnetization method of motor 1 according to embodiments of the present invention is described below with reference to Fig. 1-Fig. 8.
A：Motor 1 assemble after and Hall subassembly 500 assemble before (as shown in Figure 7) lead to predefined size to stator module 100
Direct current, the stator field of the generation fixed-direction of stator module 100, stator-rotator magnetic field interactions, rotor assembly 200 is with relative
The specific angle of stator module 100 is fixed；
B：The magnetize magnetized head 2 of frock of magnet ring is close to the rear surface of magnet ring 230, in making by after fixation by rotor assembly 200
Center positioning hole 231 on the insertion magnet ring 230 of heart locating dowel 21, it is ensured that the concentricity of magnetized head 2 and magnet ring 230, so as to ensure
The magnetic pole of magnet ring 230 is evenly distributed, and makes the circumferentially positioned hole 420 on the circumferentially positioned insertion of post 22 rear end cap, it is ensured that magnetized head 2
Special angle of the relative rotor component 200 in the circumference of rotor assembly 200, then applies magnetize electric current, magnet ring to magnetized head 2
230 magnetic pole is subjected to axial magnetic field, completes the axial charging of magnet ring 230, and magnetic pole distribution and the magnetic pole of magnetized head 2 of magnet ring 230 lead to
Magnetic field after electricity is corresponding, i.e., the magnetic pole of magnetized head 2 keeps the special angle, corresponding, magnet ring with rotor magnetic pole 220
230 magnetic pole also keeps the special angle with rotor magnetic pole 220.
After magnetizing, magnetized head 2 is removed, Hall subassembly 500 is assembled on rear end cap 400, assembling post 511 is inserted circumference
Positioning hole 420, it is ensured that Hall subassembly 500 is assembled on rear end cap 400 with specific position.
The magnet ring for motor 1 according to embodiments of the present invention magnetizes the magnetization method of frock and motor 1, after can eliminating
The influence of the machining accuracy of end cap 400 and assembly precision to the position of Hall subassembly 500, thus eliminate the machining accuracy of rear end cap 400 and
Influence of the assembly precision to rotor-position signal, and then the performance of motor 1 can be improved.
For example, such as occur the circumferentially positioned hole 420 and rear end on error, rear end cap 400 because of processing or assembly precision
There is angular deviation in the line at the center of lid 400, then the magnetic pole relative rotor magnetic pole 220 of magnetized head 2 with motor ideal axis
Deviation with equal angular, i.e., the magnetic pole relative rotor magnetic pole 220 of corresponding magnet ring 230 also offsets equal angular.Due to suddenly
Your component 500 by the location and installation of circumferentially positioned hole 420 on rear end cap 400 on rear end cap 400, correspondingly, Hall subassembly
500 also offset by identical angle, so can just offset the angular deviation produced by the magnetic pole of magnet ring 230, rotor-position
Signal will not be because the machining accuracy or assembly precision of rear end cap 400 are not enough and produce change.
Below with reference to the accompanying drawings DC brushless motor 1 according to the specific embodiment of the invention is described.
In some specific embodiments of the present invention, as Figure 1-Figure 8, motor 1 according to embodiments of the present invention includes
Stator module 100, rotor assembly 200, drive end bearing bracket 300, rear end cap 400 and Hall subassembly 500.
Wherein, Hall subassembly 500 includes Hall seat 510 and hall circuitboard 520.Hall seat 510 is arranged on rear end cap 400
On, assembling post 511 is located at the preceding surface of Hall seat 510 on that.Hall circuitboard 520 is located on Hall seat 510, Hall seat 510
On casting glue is perfused with to cover hall circuitboard 520.Thus inspection of the Hall subassembly 500 to the position of magnet ring 230 can both have been ensured
Brake is reliable, again can be in order to assembling the processing of post 511.
In order to ensure the accuracy and magnetized head 2 and the standard of magnet ring 230 relative position circumferentially positioned to Hall subassembly 500
True property, the central axis of center via 410 is overlapped with the central axis of center positioning hole 231.
Further, the rear surface of magnet ring 230 and the rear flush of rear end cap 400.So Hall subassembly 500 is not installed
When, magnet ring 230 is magnetized using the magnet ring frock that magnetizes, magnetized head 2 can be facilitated to contact the rear surface of magnet ring 230, with to magnet ring
230 carry out axial charging.
In some specific embodiments of the present invention, as Figure 4-Figure 7, circumferentially positioned hole 420 is two, and two weeks
To positioning hole 420 in the radially relative to each other of center via 410.In other words, the line of centres in two circumferentially positioned holes 420 is worn
Cross the center of center via 410.Assembling post 511 is two and is respectively fitting into two circumferentially positioned holes 420.It is possible thereby to enter
One step improves the circumferentially positioned effect to Hall subassembly 500, improves the relative stator component 100 of Hall subassembly 500 in stator module
Positional stability in 100 circumferences.
When the frock that the magnet ring magnetizes individually is magnetized to magnet ring 230, the circumferentially positioned post 22 of magnetized head 2 inserts two
In one in circumferentially positioned hole 420.
Further, as shown in Figure 4 and Figure 5, one in two circumferentially positioned holes 420 is circular locating openings, and two
In circumferentially positioned hole 420 another be along center via 410 the kidney-shaped positioning hole radially extended.In two assembling posts 511
One be that another in circular assembling post, and two assembling posts 511 be kidney-shaped assembling post, the circular assembling post cooperation exists
In the circular locating openings and kidney-shaped assembling post coordinates in the kidney-shaped positioning hole.Hall subassembly can so be facilitated
The 500 reliable installation and the accurate fit of magnetized head 2 and rear end cap 400 with rear end cap 400.
Circumferentially positioned post 22 on magnetized head 2 is circular locating dowel, and the frock that the magnet ring magnetizes individually magnetizes to magnet ring 230
When, circumferentially positioned post 22 coordinates may move in the circumferentially positioned hole 420 of kidney-shaped and in the circumferentially positioned hole 420 of kidney-shaped.This
Even if sample has mismachining tolerance, by adjusting position of the circumferentially positioned post 22 in the circumferentially positioned hole 420 of kidney-shaped, it can also protect
Demonstrate,prove the accurate fit of magnetized head 2 and magnet ring 230.Also, the circumferentially positioned Kong420Yan centers via 410 of kidney-shaped is radially extended
(i.e. radially extending along stator module 100), such magnetized head 2 can only be moved in the radially carry out micro-shifting of stator module 100, no
The circumferential position of 2 relative stator component of magnetized head 100 can be influenceed, it is ensured that the relative angle of magnetized head 2 and magnet ring 230.
