Description
Technical field
The present invention relates to technical field of motors, the especially a kind of non-brush permanent-magnet DC motor that can realize dual-control double-drive.
Background technology
Permanent-magnet brushless DC electric machine utilizes the not cutting of varying magnetic field and electromagnetism variable magnetic field of permanent magnetism, the control commutation system that permanent magnetism acquired signal and electronic devices and components is made of magnetic induction sensor realizes its running by electromagnetic field A, B, C three-phase exchange power supply, is the critical component of motor vehicles such as electric automobile, electric bicycle.But, the permanent magnetism of the permanent-magnet brushless DC electric machine in the market not commutation condition of varying magnetic field and electromagnetism variable magnetic field is insufficient, owing to completing a business transaction and produce same sex magnetic field and bump against in too early magnetic field, make that the no-load current of motor is bigger, noise is louder, and motor is heat producing losses's energy very easily, and compares with the volume motor, Motor torque is little, efficient is on the low side, effective power is less than normal, temperature rise, and can't realize required control model according to user's needs.
Summary of the invention
The technical problem to be solved in the present invention is: propose a kind of energy conversion efficiency height, improve moment of torsion, reduce temperature rise and can realize the dual-control double-drive permanent-magnet direct-current brushless motor of different mode of operations according to user's needs.
The technical solution adopted in the present invention is: a kind of dual-control double-drive permanent-magnet direct-current brushless motor, comprise rotor and stator, the quantity of the armature pole that is provided with on the described stator is 36,36 armature pole circumference are divided into 4 equal portions for 360 °, 9 armature poles are arranged in every equal portions, that be provided with on the described rotor and the quantity corresponding permanent magnetic steel of stator are 32,32 permanent magnetic steel circumference are divided into 4 equal portions for 360 °, 8 permanent magnetic steels are arranged in every equal portions, the armature pole quantity of per 90 ° of diagonal angle additions is 18, the quantity of permanent magnetic steel is 16, and 18 armatures of per 90 ° of diagonal angle additions are one group of three phase winding very, in 360 ° of the circumference two group of three phase winding is arranged.
The present invention comprises that further described permanent magnetic steel is watt shape or plain film shape.
The invention has the beneficial effects as follows: by corresponding 32 permanent magnetic steels of 36 armature poles, and with in armature pole and the permanent magnetic steel circumference 360 ° be divided into 4 equal portions, 9 armature poles and 8 permanent magnetic steels are arranged in every equal portions, 18 armatures of 90 ° of diagonal angle additions are one group of three phase winding very, realize two group of three phase winding in 360 °, such structure makes the present invention compare with the motor of volume of the same type that the motor output torque is big, caloric value is low, energy conversion efficiency is high, has solved the technical bottleneck of the big current control system of high-power double-control double-drive permanent-magnet direct-current brushless motor; And the present invention can realize that by such structure dual-control double-drive, two control are singly driven or the two electrical machine working modes that drive of single control, makes the user can control the real work pattern of motor according to the needs of oneself.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Among the figure: 1. rotor; 2, stator; 3, armature pole; 4, permanent magnetic steel.
Embodiment
The present invention is further detailed explanation with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, a kind of dual-control double-drive permanent-magnet direct-current brushless motor, comprise rotor 1 and stator 2, the quantity of the armature pole 3 that is provided with on the described stator 2 is 36,36 armature pole 3 circumference are divided into 4 equal portions for 360 °, 9 armature poles 3 are arranged in every equal portions, the quantity with stator 2 corresponding permanent magnetic steels 4 that is provided with on the described rotor 1 is 32,32 permanent magnetic steel 4 circumference are divided into 4 equal portions for 360 °, 8 permanent magnetic steels 4 are arranged in every equal portions, and armature pole 3 quantity of per 90 ° of diagonal angle additions are 18, and the quantity of permanent magnetic steel 4 is 16,18 armature poles 3 of per 90 ° of diagonal angle additions are one group of three phase winding, in 360 ° of the circumference two group of three phase winding are arranged.The institute
18 armature poles 3 of the utility model 90 ° of additions in every diagonal angle are one group of three phase winding, and such structure can be seen a drive motors as, and the utility model comprises two groups of such structures, also just can see two drive motors as.In the course of work of reality, the user can utilize software program to come the controlling and driving motor as required, therefore, the utlity model has three kinds of mode of operations: dual-control double-drive, two control are singly driven and single control is singly driven.Dual-control double-drive is: control two drive motors simultaneously and work simultaneously, and draw two tappings; Two controls singly drive for: control two drive motors and work simultaneously, the tapping of two drive motors is merged into a leading-out end; Single control singly drive for: control one of them drive motors work arbitrarily, and draw a tapping.
During the utility model work, provide three-phase exchange power supply by the motor lines assembly for motor, owing to be wound with winding on the armature pole 3, when electric current passed through, according to electromagnetic induction, electrical conductor was subjected to the effect of power in magnetic field, therefore cause rotor 1 rotation, output mechanical energy from the axle.
According to other execution mode of the present utility model, the number of armature pole 3 can be odd or even number, but the number of armature pole 3 pairing permanent magnetic steels 4 is necessary for even numbers, and the number of armature pole 3 and permanent magnetic steel 4 is four multiple, can make like this armature pole 3 and permanent magnetic steel 4 can be in circumference 360 ° be divided into 4 equal portions, and the number of armature pole 3 equates in condition with the sheet number of permanent magnetic steel 4.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.
