Description
Technical field
The utility model is a kind of New-type electric machine technical field, but the outer-rotor permanent magnet motor stator that to be specially a kind of partial stator tooth be the assembly unit stator structure.Compare with common outer-rotor permanent magnet motor, automatic winding is more convenient on the one hand for this electric machine structure, has higher copper factor; Have littler backlash on the other hand, can reduce the cogging torque of motor like this, reduce the noise of motor.
Background technology
The traditional stator core construction form of the general employing of the stator of magneto; The iron core of stator punching is processed by the disposable punching press of combined type progressive die; Stator core itself is fit to large-scale production, low cost of manufacture, but be not easy to use automatic coil winding machine to carry out large-scale production; And copper factor is low, and the manufacturing cost of stator winding is high.(U.S. Patent number: US20090302694) proposed a kind of the motor external stator to be disassembled into several denticles, winding that coiling in advance is good and insulating barrier are inserted in stator tooth to existing direct winding technology patent together, and then stator tooth is combined into an integral body.Can reach the purpose that improves the motor copper factor though do like this, this structure is only applicable to internal rotor/outer stator structure.In external rotor/internal stator structure, patent CN101931274A provides a kind of modular motor stator structure that can radially insert, to improve the motor copper factor, to reduce the winding manufacturing cost.Patent CN1476144 disassembles into stator body and several tooth bodies with stator, and tooth body and stator body adopt straight trough shape and alignment pin to closely cooperate and obtain an integral body.Above-mentioned these methods are all disassembled into monodentate with the motor stator tooth, are feasible for this method of all disassembling of the big motor of power; For the low-power machine below the 50W, because the size of motor stator is little, the monodentate of all disassembling is combined into one and accomplishes very difficulty of motor stator.
Summary of the invention
To the low-power machine problem, the utility model provides a kind of winding efficiency that improves, reduce the winding repair rate, can make motor have the outer-rotor permanent magnet motor stator of higher copper factor simultaneously.The utility model can make motor have little backlash, reduces the cogging torque of motor, reduces the noise of motor.
The specific embodiments of the utility model is following: the outer-rotor permanent magnet motor stator of the utility model; Stator includes several stator tooth unit that are embedded in the stator matrix; Wherein whenever embed a stator tooth unit at a distance from a stator matrix, the quantity of stator tooth unit equates with the quantity of stator matrix.
The quantity of said stator tooth unit is even number.
The said stator matrix includes stator core matrix, stator core coil, and the stator core coil winding is on the iron core matrix, and the stator tooth unit includes stator tooth iron core unit, stator tooth iron-core coil, and the stator tooth iron-core coil is wound on the stator tooth iron core unit.
Said stator iron core matrix is laminated by some stator punching substrates and forms, and the stator tooth iron core unit is laminated by the punching of some stator monodentates and forms.
Said stator punching substrate and the punching of some stator monodentates are disassembled through punching press on a stator punching and are formed.
The utility model is owing to adopt the structure that whenever embeds a stator tooth unit at a distance from a stator matrix; Be that the partial stator tooth adopts combinable structure, the utility model can be used for the low-power external rotor magneto, the utlity model has following advantage: it is little that low-power machine is decided sub-punching size; Because disassembled half the stator tooth; The gap of residual tooth has increased several times on the stator core matrix, has solved the problem of machine coiling, improves winding efficiency; Reduce the winding repair rate, motor can have higher copper factor simultaneously; In addition, the utility model can make motor have little backlash, can reduce the cogging torque of motor, reduces the noise of motor.The utility model is a low-power external rotor permanent magnet motor stator a kind of reasonable in design, convenient and practical.
