Abstract
The utility model discloses a motor rotor comprising a cylindrical rotor body. A plurality of engagement recesses used for fixing tile-shaped magnets are provided on the outer wall of the rotor body. A plurality of engagement columns are arranged on the outer wall of the rotor body. Engagement positions are provided on two sides of the engagement columns. One engagement recess used for fixing the tile-shaped magnet is formed by an engagement position between two adjacent engagement columns. According to the utility model, the plurality of engagement recesses used for fixing tile-shaped magnets are provided on the outer wall of the rotor body; the length of the engagement recess equals the length of the tile-shaped magnet; the depth of the engagement recess equals the thickness of the tile-shaped magnet; and the length and depth of the engagement recess can be subjected to free matching adjustment according to the size design of the magnetic tile, such that the tile-shaped magnets can be firmly engaged in the engagement recess. Assembly is convenient, and connection is firm. The motor rotor provided by the utility model has the advantages of simple structure and convenient processing and manufacturing. With the motor rotor, the motor is safer, and service life is long.
Description
[technical field]
The utility model relates to a kind of rotor of motor.
[background technology]
Motor, particularly brushless electric machine generally are to be provided with iron core parts such as (also being magnetic core) in a shell.Iron core comprises stator and rotor, is wound with copper cash at stator, and rotor normally is embedded in the interior location of stator, and rotor is provided with magnet.There is following defective in existing rotor: rotor relies on glue to fix with being connected of magnet fully, and the meeting that the glue fixed form has corrosion rotor; The connection that has is insecure, magnet breaks away from rotor easily, because there is unsteadiness in glue itself, directly by the bonding rotor magnet of glue, behind the long high-speed cruising of motor, have and get rid of the potential safety hazard of taking off magnet, directly cause product stuck, burn even may cause that institute sets and occurs safety problem fully.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of simple in structure, and rotor and magnet are connected firmly, safety, the iron core of the motor of long service life.
The purpose of this utility model is achieved in that
A kind of rotor of motor is characterized in that the rotor body that it comprises drum, and the outer wall of described rotor body is provided with a plurality of draw-in grooves for fixing watt shape magnet.
The rotor of aforesaid a kind of motor is characterized in that the outer wall of described rotor body is provided with a plurality of clip-connecting rods, and the both sides of clip-connecting rod are provided with screens, and the screens between adjacent two clip-connecting rods forms a draw-in groove for fixing watt shape magnet.
The rotor of aforesaid a kind of motor is characterized in that the inwall of described rotor body is provided with a plurality of T type joint pins.
The utility model is provided with a plurality of draw-in grooves for fixing watt shape magnet at the outer wall of rotor body, and the length of draw-in groove equals watt length of shape magnet, and the degree of depth of draw-in groove equals watt thickness of shape magnet; The length of draw-in groove and the degree of depth can be done any matching adjustment with the magnetic shoe size design, can make like this that watt shape magnet is very firm to be clamped in the draw-in groove, and be easy to assembly, is connected firmly.And simple in structure, convenient processing and manufacture makes motor safer, long service life.
