Performance is bad, and for non-brush permanent-magnet DC motor, when demand power is higher, in the case that operating mode is relatively severe, and permanent magnetism
The electric current of DC brushless motor is larger, and the eddy-current loss of iron core also increases therewith, to which stator core and coiling Wen Sheng are also higher,
And the ventilation and heat component of non-brush permanent-magnet DC motor is more complicated or cost is higher.
Utility model content：
For the present situation of the prior art, the purpose of this utility model is to provide a kind of Circular Winding permanent-magnet DC brushless
Motor, which is not only simple in structure, control accuracy is high, reliability is high, fault-tolerant ability is strong, and has better heat radiation energy
Power.
To achieve the goals above, the technical solution of the utility model is：A kind of Circular Winding non-brush permanent-magnet DC motor,
Including stator, Circular Winding, rotor and shaft；The stator is a cylindrical stator iron core；Two circles of the Circular Winding
Radially correspondence is uniformly distributed on stator core surfaces externally and internally on side；The rotor is located in the stator, the stator with it is described
Radial air gap is equipped between rotor.
As an improvement of the above technical solution, stator inner surface or outer surface are uniform-distribution with the stator radially protruded
Tooth body forms stator slot between two neighboring stator tooth body；It is fixed that one circle side of the Circular Winding is set to inner or outer side
In pilot trench, another circle side is set on outer surface or the inner surface of the stator core diametrically answered with stator slot.
As an improvement of the above technical solution, stator inner surface and outer surface are uniform-distribution with the stator radially protruded
Tooth body, per stator slot is formed between two adjacent stator tooth bodies of face, two sides stator slot radially corresponds；Diametrically answer
It is wound with Circular Winding in two stator slots.
The beneficial effects of the utility model are, using Circular Winding not only increasing heat radiation area, while having half winding
It is directly exposed in air, better heat-radiation effect；The motor is with simple in structure, control accuracy is high, reliability is high and holds simultaneously
The advantages such as wrong ability is strong.
