Motor is as electromagnetic drive important core equipment, and there are many technological difficulties in designing and processing.Wherein it is directed to
High reliability, high efficiency, high controllability, loss of weight etc. have all carried out corresponding program analysis compared with.Led since motor uses
Magnetic ferromagnetic material is main composition with electric conductivity electromagnetic material, and the reduction of its weight is only capable of being embodied in increase energy density,
Therefore it is ideal scheme to select magneto.Appropriate increase motor speed is used at the same time to reduce the method for motor volume, at the same time
It is equipped with appropriate deceleration device and reaches comprehensive volume and weight minimum design.
Country greatly develops industry 4.0 and plans at present, and specific developing goal, space machine are it is also proposed to Robot industry
Tool arm technology can be applied to normal domestic field, the development with mobile robot industry.
Requirement takes into account integrity problem, cost and the cost problem of motor while weight and volume is reduced.Work as motor
Size spy hour, its teeth portion intensity is too small, can there are coiling it is difficult the problem of.
The content of the invention
The invention aims to take into account small weight, small size and the reliability of motor, solve when motor size is special small,
Its teeth portion intensity is too small, can there are coiling it is difficult the problem of, there is provided a kind of compact permanent magnetic brushless sectional type iron core around
Line method.
A kind of compact permanent magnetic brushless sectional type iron core method for winding of the present invention, the compact brushless, permanently
Motor includes hollow multi-pole permanent-magnetic rotor and is embedded to the stator of Hall element, and the iron core of stator is segment core structure, in stator
Multiple stator tooths are set on iron core, a stator slot is formed between each two stator tooth, is buried in stator slot by three-phase symmetrical mode
Enter three Hall elements；
Coiling three-phase symmetric winding on the stator teeth, the method for coiling three-phase symmetric winding are：
The stator core of segmental structure is fixed on winding mould, and is fixed with pressing plate；Reserved between stator tooth
The gap of bobbin winding head size carries out manual coiling；After a complete stator tooth, it is further continued for around next stator tooth, disposably by one
All stator tooths are all wound under phase.
Advantages of the present invention：It is to use a kind of special wire winding process in patent of the present invention, ensures in motor tooth
When portion's mechanical strength is smaller, ensure coiling precision, reduce complex process degree.Meanwhile this wire winding does not have to solder joint wiring,
Increase the functional reliability of motor.
The present invention is a kind of low inertia brushless, permanently torque motor, its driving as space or civilian joint of mechanical arm
Device, can directly meet the requirement of mechanical arm tail end slow-speed of revolution operation, relative to using high-speed electric expreess locomotive and tooth in the prior art
Wheel deceleration device is supporting to reach the mode of requirement, realizes simple in structure, and the complicated process of electric system reduces；While by
Hollow disc type is used in rotor, maximum torque output can be reached on the premise of identical weight, is more applicable for space flight neck
Domain.And embedment hall device method is used, reduce motor entire length, to reducing weight, raising power density all has very big
Benefit.This wire winding does not have to solder joint wiring, increases the functional reliability of motor.

Embodiment
Embodiment one：Illustrate present embodiment with reference to Fig. 1 to Fig. 3, one kind described in present embodiment is compact
Type permanent magnetic brushless sectional type iron core method for winding, the compact permanent magnetic brushless include hollow multi-pole permanent-magnetic rotor and
The stator of Hall element is embedded to, the iron core of stator is segment core structure, and multiple stator tooths, each two are set in stator core
A stator slot is formed between stator tooth, Hall element is embedded with partial stator groove；
Coiling three-phase symmetric winding on the stator teeth, the method for coiling three-phase symmetric winding are：
The stator core of segmental structure is fixed on winding mould, and is fixed with pressing plate；Reserved between stator tooth
The gap of bobbin winding head size carries out manual coiling；After a complete stator tooth, it is further continued for around next stator tooth, disposably by one
All stator tooths are all wound under phase.
Being driven using high-speed electric expreess locomotive to solve existing space mechanical arm needs associated gear deceleration device, makes motor
The problem of system structure is complicated.Motor involved by present embodiment is as far as possible small motor, in order to reduce motor axial direction body
Product, mode in motor slot is embedded to using by Hall element.Therefore, the object that method for winding described in present embodiment is directed to is teeth portion
Narrow, motor pole number is excessive, the less sectional type magneto of motor outside diameter.The independent winding by hand pattern of motor sectional type.Under one phase
Stator tooth wind together, save terminal box welding, ensure the security reliability of motor.
In the prior art, can be by the way of machine coiling, but for tooth for the larger blocking type electric engine of outside diameter
The motor of the narrow load of shape, the facewidth are less than 1 millimeter of motor, tooth may be caused to deform by the way of using machine, because of present embodiment pin
To be the narrow motor of teeth portion, so present embodiment is by the way of winding by hand.

Shown in Fig. 2) on, and fixed with two block pressur plates (as shown in Figure 3).The gap that bobbin winding head size is reserved between stator tooth carries out
Manual coiling.After a complete stator tooth, it is further continued for around next stator tooth.So by stator tooth all under a phase all around
It is good.
The top of single stator tooth can be just put down in the groove of winding mould.The position of coiling is not interfered with so.On
There is hole in face, in order to install pressing plate additional.
Embodiment two：Present embodiment is described further embodiment one, is ensureing overall threephase stator
On the premise of winding is in symmetry status, umber of turn in the stator slot of placement Hall element is set to be less than the circle for not placing Hall element
Number.
Overall threephase stator winding is in symmetry status, to ensure that magnetic flux is uniformly distributed as far as possible, to reduce the power of magneto
Square fluctuates.
