Description
Technical field
The utility model relates to motor device technical field, especially a kind of inner-rotor brushless motor.
Background technique
It is well known that brushless motor is widely used, and it is easy for installation, liked in life by many people.Internal rotor
Brushless motor: refer to rotor in the brushless motor of internal rotating, our common motors are largely inner rotor core, this knot
The advantages of structure includes: that winding is directly contacted with shell, and heat can be exported by shell, be isolated from the outside inside motor, is avoided outer
Portion's sundries enters inside.However the rotor of inner-rotor brushless motor, it is more complicated that permanent magnet installs the assembling process to rotor,
Production cost is higher.
Utility model content
In order to overcome the shortcomings of that the permanent magnet mounting process on existing inner-rotor brushless rotor is complicated, this is practical new
Type provides a kind of inner-rotor brushless motor, by permanent magnet be embedded in rotor it is fast on, then using fixinig plate lock.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of inner-rotor brushless motor, including it is outer
Shell is fixed with stator on outer casing inner wall, and interior of shell center is equipped with rotor, and the rotor includes shaft, and both ends of the shaft passes through axis
It holds and is fixedly connected on shell both ends, rotor block is fixed in the middle part of shaft, rotor block outer surface is equipped with permanent magnet, rotor block outer surface
Equipped with the dovetail groove for mosaic magnet, rotor block one end is equipped with the fixed plate for fixed permanent magnet.
Further, including dovetail groove one end is set as openning shape, and the dovetail groove other end is set as closed.
Further, the abaculus for inlaying dovetail groove, abaculus and dovetail groove interference fit are equipped with including permanent magnet.
The utility model has the beneficial effects that a kind of inner-rotor brushless motor of the utility model, permanent magnet is embedded in
It on rotor is fast, is then locked using fixinig plate, the assembling process of the rotor is simple, and assembly technology is easy, has greatly saved interior
The assembly time of rotor brushless motor, improves production efficiency.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.

Specific embodiment
If Fig. 1 is the structural schematic diagram of the utility model, a kind of inner-rotor brushless motor, including shell 1,1 inner wall of shell
On be fixed with stator 2,1 inside center of shell is equipped with rotor 3, and the rotor 3 includes shaft 4, and 4 both ends of shaft are fixed by bearing
1 both ends of shell are connected to, rotor block 5 is fixed in the middle part of shaft 4,5 outer surface of rotor block is equipped with permanent magnet 6,5 outer surface of rotor block
Equipped with the dovetail groove 7 for mosaic magnet 6,5 one end of rotor block is equipped with the fixed plate 8 for fixed permanent magnet 6.Fixed plate 8
Be fixed by screws in rotor it is fast on.
In conjunction with shown in Fig. 2-3,7 one end of dovetail groove is set as openning shape, and 7 other end of dovetail groove is set as closed.Permanent magnetism
Body 6 is equipped with the abaculus 9 for inlaying dovetail groove 7, and the abaculus 9 and dovetail groove 7 are interference fitted.Abaculus 9 on permanent magnet 6 from
7 open end of dovetail groove is filled into dovetail groove by extrusion tooling pressure, the other end closing of dovetail groove, before avoiding the continuation of abaculus 9
Row skids off dovetail groove 7, plays the role of blocking, fixed plate 8 is then covered the side in rotor block 5 and is the opening of dovetail groove 7
It at end, is fixed by fixed screw, fixed plate 8 covers the opening of 7 side of dovetail groove, plays the role of fixed abaculus 9, simultaneously
The outer diameter of fixed plate 8 is less than the outer diameter of rotor block 5.
In use, opening up dovetail groove 7 on 5 surface of rotor block, the abaculus 9 on permanent magnet 6 is from 7 open end of dovetail groove by squeezing
Pressure tooling pressure be filled into dovetail groove, then by fixed plate 8 cover the side in rotor block 5 and be dovetail groove 7 open end at, pass through
Fixed screw is fixed, and the rotor that this is assembled into is installed into shell, is assembled into inner-rotor brushless motor, the assembly of the motor
Journey is simple, and assembly technology is quick, has greatly saved the assembly time of inner-rotor brushless motor, has improved production efficiency.
It is described above to be merely exemplary for the utility model, and not restrictive, those of ordinary skill in the art
Understand, in the case where not departing from spirit and scope as defined in the appended claims, many modifications can be made, change or wait
Effect, but all will fall within the protection scope of the utility model.
