Description
Technical field
The present invention relates to the DC Brushless Motor art, the dislocation that refers in particular to that a kind of compact conformation, motor operation do not have the dead angle, startability is good and greatly reduce cost drives DC Brushless Motor more.
Background technology
As shown in Figure 1 to Figure 3, Xian You DC Brushless Motor includes a rotor R, a stator P, one drive circuit IC usually; This rotor R is around this stator P, and this stator P polarity tooth (including P1, P2, P3, P4) quantity equates with rotor R magnetic pole (including R1, R2, R3, R4) quantity and is corresponding on circumference.Like this, when carrying out the polarity switching in the motor operation, because each all stator polarity tooth mid points is corresponding with each rotor magnetic pole mid point, all stator polarity teeth must switch simultaneously, in the moment that stator polarity tooth switches, the radial load of motor maximum and circumferentially component be zero, so the motor stall has the dead angle, when stopping because of motor again, because stator polarity tooth P1, P2, P3, P4 and rotor magnetic pole R1, R2, R3, R4 correspondence respectively inhales mutually, make each each magnetic pole mid point of polarity tooth mid point and rotor of stator be in the phase place of aliging, therefore, in the moment of motor starting, the active force that each magnetic pole and magnetic field of each polarity tooth magnetic field of stator and rotor produces is radially reaching maximum, but circumferentially be zero, namely the starting torque of motor is zero, the startup difficulty of motor; And, because the minimal torque of motor is zero, thus the amplitude ratio of motor greater than 1, the change in torque during motor operation is big, motor is shaken easily, the operation noise is big.
Start difficult problem at DC Brushless Motor, following scheme arranged at present:
One, the polarity tooth with stator is designed to the asymmetric profile of both sides size, when motor is static like this, stator polarity tooth and rotor magnetic pole suction mutually can make rotor magnetic pole mid point and stator polarity tooth mid point depart from small phase place, thereby guarantee that the moment of torsion of motor was non-vanishing when energising started, reach the purpose of motor starting, power is used in the dependence that is in operation makes motor to turn round continuously; By such design, though motor can start and operation, but the moment of torsion when starting is relatively very little, so load starts difficulty when big, the zero moment of torsion of motor still exists, and the moment of torsion amplitude ratio of motor does not improve, so the dead angle still exists during stall, motor is easily shaken, and the motor operation noise is big, and motor only is suitable for the not high occasion of little load quality requirements to be used.
Two, adopting maximum at present is to solve with the three-phase motor circuit, but the circuit cost costliness of three-phase direct-current brushless motor circuit, its cost be tens of times of common motor drive circuit normally, circuit complexity and circuit space are relatively large, circuit needs shortcomings such as plug-in in micro motor, and its application is restricted;
For example: 200920169532.2 1 kinds of brushless DC motors that drive in non-wholecircle week of patent, this patent specifically is that a kind of three stator polarity teeth of non-uniform Distribution are one group three-phase motor, obviously there is above-mentioned weak point in it;
And for example patent 200810190379.1 Brushless DC motors and driver element thereof, being proficient in the industry, the personnel of technology can find, its basic scheme is, all stators of motor have identical profile, its stator number of teeth is quantitatively corresponding one by one with the rotor magnetic pole number, the corresponding drive circuit of stator, its stator is evenly staggered in axial simple stack but at radially relative phase, though do not mention the dead angle problem that can effectively solve motor in this patent, but its scheme that provides has substantially just solved the problem of motor zero moment of torsion, and its motor operation does not have the dead angle; Because it is in axial stack by two or more stators, and the shared axial space ratio of the insulating material of each stator and line bag is very big, so just wasted the axial space of motor preciousness, the total silicon steel sheet of all stators is very little at the whole axial space proportion of the relative rotor of axial gross thickness, and its load capacity is very little.As everyone knows, in the external rotor DC Brushless Motor, the height of motor is more high, its part precision and moulding are more difficult, the balance of its rotor is more poor, therefore, and under the situation of motor equal height, it is impossible obtaining the load capacity identical with the conventional DC brushless motor, otherwise, obtain higher motor load ability, must increase external rotor greatly at axial height, when highly reaching one regularly, its inevitable cost that increases procedure for producing greatly.In addition, when it applied on the internal rotor DC Brushless Motor, because magnet is less in axial effective length utilance, and the magnet of inner rotor motor was generally expensive magnet steel or rare earth material, and the cost of its magnetic material waste is just relatively large;
Also have, 200910025738.2 1 kinds of segmentation rotor shapes of patent reluctance motor, it is three-phase 6/4 structure or four 8/6 structure or three-phase 12/8 structure mutually, it is inner rotor motor, rotor magnetic pole quantity is lacked than stator polarity number of teeth amount, and there is expensive, the institute number of drawbacks such as big that takes up space equally in it.
Therefore, need work out a kind of new technical scheme and solve the problems referred to above.
Summary of the invention
In view of this, the present invention is directed to the disappearance of prior art existence, its main purpose provides a kind of dislocation DC Brushless Motor that drive more, and its compact conformation, motor operation do not have the dead angle, startability is good and compare traditional three-phase motor greatly reduces cost.
