Description
Technical field
The present invention relates to a kind of parts of brushless coreless disc-type permanent magnet motor, particularly relate to the winding construction of the stator in it and there is the motor of this stator winding structure.
Background technology
Motor stator comprises ribbon core motor and iron-core less motor two kinds now.The motor stator of ribbon core is made up of iron core and the coil be wrapped on iron core, owing to exposing the coil sections out-of-shape of top end face at iron core and bottom face, the obstruction of any is produced when rotor is installed in the stator, namely rotor dress does not enter, even if or the operation of installing rotor of entering also has an impact, in addition when stator is arranged on stator casing, these coil sections in irregular shape exposing iron core top end face and bottom face also affect stator self and install, therefore, stator overlap at every turn carefully connect the wire after all to carry out trimming.Iron-core-free structure is due to iron-core-free, power of motor can only do very little, iron-core-free structure is again injection moulding or form structure, injection moulding or form are generally be placed in mould by the coil that coiling is good, injection moulding or pour into integral shaping technique, the stator field air gap adopting this technique to make is larger, and magnetic field power density utilance is low, so general efficiency is also lower.As Chinese patent: " a kind of new structure (CN02132315.1) of disk type electric machine stator ", its disc type stator is made up of coil windings, thermosetting material, coil windings is solidificated in thermosetting material body, its coil windings by several with the polygonal coil of one or more wire coiling stacked and some angles that mutually staggers.But, in the brushless coreless disc-type permanent magnet motor of three-phase, coil windings in motor stator at least needs 3 pairs of lead-out wires and is connected could normally works with external circuit, therefore, coil windings needs that the positive integer of 3 coil doubly is superimposed could be used, because each coil itself has certain thickness, especially when needing the power of motor larger, then need the coil of more number to carry out the coiling number of turns that is superimposed or increase single coil to realize, make the thickness of the coil windings be built up larger, thus make the volume of the stator produced larger, increase the volume of motor.Simultaneously, motor operationally, the two sides that rotor is arranged on stator are rotated, what can utilize during machine operation is the magnetic field that the straightway of each coil and epitrochanterian magnet steel corresponding part and magnet are strafed limit and produced, because each coil in coil windings and rotor normally be arranged in parallel, therefore, the magnetic field produced away from the coil of rotor can become more weak when arriving rotor, make the magnetic utilance of motor lower, the Motor torque produced is little, and there are differences due to the distance between each coil in coil windings and the rotor of both sides, technical staff is difficult to the actual power demand size accurately designing motor.Also have, due to the loop configuration that the single coil being built up coil windings is all plane, namely to strafe limit equal for inside and outside invalid edges and the magnet of coil, therefore the coil windings be built up is after being injection molded into stator, the outer edge portion of coil windings cannot coordinate with the inside and outside convex shape of stator, makes the structural strength of the stator be injection molded into lower.Just because of the existence of these defects above-mentioned, make existing brushless coreless disc-type permanent magnet motor cannot realize the production application of heavy-duty motor.
