Abstract
The invention relates to a winding method of a novel efficient slotted motor stator. The winding method comprises the following steps of: cutting a stator tooth, wherein the left stator is of a circular shape with a gap, and the top width of the cut stator is not greater than that of the tooth; after independently winding a coil, sleeving the coil on a single tooth; embedding the tooth wound by the coil into the corresponding gap on a stator ring; and bonding a joint by use of glue or glue containing iron powder. The winding method of the novel efficient slotted motor stator provided by the invention can be used for solving the problem that in the prior art, the slot full rate of the motor is not high, the motor performance is poor, the working and assembling difficulty of the motor is higher, and the production efficiency is low. On the one hand, the slot full rate is improved and reaches above 80%, and the motor performance is greatly improved. On the other hand, the working and assembling difficulty is reduced, and the production efficiency is improved.
Description
Technical field
The present invention relates to field of motor manufacturing, relate in particular to the winding structure of groove motor stator.
Background technology
Motor is by rotor and stator and other accessory, such as end cap, and the compositions such as bearing.Motor can be divided into direct current machine by the character that makes electricity consumption, alternating current machine and DC and AC universal electric machine.Direct current machine has again brush and brushless dividing.It is the line bag that the brushless motor rotor is arranged, by brush power supply, stator band permanent magnet; Brushless DC motor rotor band permanent magnet, stator are the line bags, power by electronic driver.Fig. 1 is the cross section schematic diagram of typical brshless DC motor.Middle circle represents rotor 1, the stator 2 of outside, tooth 3, opening 4 and groove 5.Enamelled wire from opening part around to groove the inside.Only illustrated two groove the insides that coil 6 is arranged among the figure, in fact all grooves coil has been arranged.The insulation isolation is arranged between stator and the coil in addition.Also have a kind of structure be exactly stator 7 are cylindrical shapes, anodontia slotless, as shown in Figure 2.Then the normally first coiled tubulose of enamelled wire is embedded between stator and the rotor.Dotted line represents the internal diameter border of coil among the figure.No matter be which kind of structure, how much directly related with motor performance coiling is, and the cross section gross area of enamelled wire is commonly referred to copper factor with the ratio of the cross section gross area of groove.Same rotor, the motor of stator, if copper factor is large, performance is all right.The machine common copper factor that winds the line only has about 30%, and the copper factor that manually winds the line can reach 50% or higher.How improving copper factor is a vital research topic.It is that stator is separated into toothed trifle 8 from the centre of tooth and tooth that a kind of method is arranged, again with wire-wound on each trifle, as shown in Figure 3.Such copper factor can be high, after each pitch winds line, is combined into a complete stator, as shown in Figure 4 again.
Summary of the invention
The present invention proposes a kind of novel efficient groove motor stator and winding mode thereof, it is not high to be used for overcoming in the prior art motor copper factor, motor performance is not good and work assembling difficulty is higher, the problem that production efficiency is low, the technical solution adopted in the present invention is: a kind of novel efficient has groove motor stator winding mode, may further comprise the steps:
(1) stator tooth is cut, so that the remaining stator that gets off is with the breach ring-type, the width at stator top is not more than the width of tooth after the cutting;

The tooth that (3) will wind coil is embedded into corresponding indentation, there on the track ring;
(4) at seam crossing with glue or to contain the glue of iron powder bonding.
The top of the rear stator of cutting is sharp cone distal or other shape in the described step (1);
Described step (2) coil adopts accurate winding mode or non-accurate winding mode to twine, so-called accurate coiling refers to the complete arrangement of copper cash, there is not juxtaposition, copper factor reaches maximum, coiling is still saved time than common mode, also can how improve copper factor and motor performance around some lines, adopt the certain better effects if of accurate coiling;
Described high efficiency has groove motor stator winding mode to comprise that also step (5) is divided into two halves or more again with the notched ring-type of well cutting in the step (1), after all coils winds line, again with the stator amalgamation of piecemeal together, at seam crossing with glue or to contain the glue of iron powder bonding; Also can open an osculum at seam crossing and add welding again, then whole stator installs in the shell;
Further, in the bottom of tooth, namely near the stator inner wall place, a hole is set, then is fixed to all teeth on two annulus at stator two ends with screw or rivet;
Further, at the top of tooth, namely near stator outer wall place, a hole is set, then is fixed to all teeth on two annulus at stator two ends with screw or rivet;
Adopt above-mentioned winding mode, it is not high to have overcome in the prior art motor copper factor, and motor performance is not good and work assembling difficulty is higher, the problem that production efficiency is low, can improve on the one hand copper factor, copper factor can be brought up to more than 80%, greatly improves the performance of motor; On the other hand, reduction work assembling difficulty is enhanced productivity.
A kind of high efficiency has the groove motor stator, comprises employing:
(1) stator tooth is cut, so that the remaining stator that gets off is with the breach ring-type, the width at stator top is not more than the width of tooth after the cutting;
(2) coil is independently wound after, be inserted in above the single tooth or directly coil around to tooth;
The tooth that (3) will wind coil is embedded into corresponding indentation, there on the track ring;
(4) at seam crossing with glue or to contain the glue of iron powder bonding, the stator structure that this four step makes.
