Description

A kind of outer rotor brushless motor stator
 
Technical field
The utility model relates to outer rotor brushless motor technical field, is specially a kind of stator structure of outer rotor brushless motor.
Background technology
Current outer rotor brushless motor stationary part, what all adopt is that enamelled wire is wound in the groove of jet-bedding silicon steel sheet, under this traditional structure condition, the efficiency of motor is difficult to the progress that makes a breakthrough, especially for using the motor that battery is the similar model plane class of drive energy, require it is very important index to electric efficiency, how lifting motor decreasing efficiency motor own loss is the important goal that the industry is pursued.
Utility model content
The utility model adopts the winding structure of specially-shaped, forms a tubular enameled wire loop, is enclosed within the iron core ring of strip-wound type, replace traditional enamelled wire and be wound on the silicon steel sheet of jet-bedding structure, become the major part of motor stator.
Design of the present utility model: a kind of outer rotor brushless motor stator, described motor stator is made up of tubular enameled wire loop and strip-wound type circle ring iron core, and solenoid is enclosed within circle ring iron core cylindrical, and entirety is fixed on stator internal frame and forms; Described tubular enameled wire loop is shaped by enamelled wire coiling, comprises single cord coiling and multiply and stranded wire and around form; Described circle ring iron core is high permeability, high magnetically saturated very thin iron-alloy band material winding is made.
Described tubular enameled wire loop is oblique winding structure.
Described tubular enameled wire loop is rhombus winding structure.
Described tubular enameled wire loop is polygon winding structure.
Described tubular enameled wire loop is straight line winding structure, comprises lap winding and wave winding form.
This motor stator is arranged on stator internal frame, is connected with motor shaft by bearing, and outside connection permanent magnet outer rotor is also encapsulated in a formation complete outer rotor brushless motor in electric machine casing.The special winding structure of this motor stator can obtain larger winding space, and copper olse is reduced; Adopt the strip-wound type iron core of special material itself to have the electric parameter more excellent than silicon steel sheet, motor iron loss is also reduced.Therefore whole motor efficiency is improved.
Motor stator structure of the present utility model, when same volume is suitable with permanent magnet consumption, the power density of motor is larger, efficiency is higher has significant energy-saving effect.
