Abstract

The invention relates to a slotless permanent-magnet machine comprising stator components. The invention is characterized in that: said stator components comprise a false stator (5); an iron core (6) and a stator winding (7). Wherein, said false stator (5) is sheathed outside the iron core (6); said stator winding (7) is arranged of wire outside the false stator (5); and said false stator (5) is made from insulation material. The invention replaces the groove and tooth on the punching sheet of stator iron core with insulated false stator (5) to effectively solve the problem of slot electric machine as slot effect, hysteresis loss, eddy current loss and eddy current loss. The invention has higher load efficiency, continuous speed regulation, better acceleration property, higher overload capacity, smaller volume, stable operation, small torque fluctuation and simple manufacture process.

Description

Slotless permanent magnet motor
Technical field
The present invention relates to a kind of magneto, particularly a kind of slotless permanent magnet motor.
Background technology
At present, magneto on the market all is that the groove motor is arranged, and its common issue with is to have shortcomings such as slot effect, magnetic hysteresis loss, eddy current loss, magnetic saturation.Conventional method weakens slot effect and adopts helical teeth, has improved difficulty of processing on the one hand, can not thoroughly eliminate magnetic hysteresis loss on the other hand.Existing slotless electric machines winding adopts tubular or sleeve shaped coiling, complex process, and distribute and the groove motor windings is not arranged symmetrically, torque ripple is also bigger.
Summary of the invention
The purpose of this invention is to provide a kind of slotless permanent magnet motor to solve the above-mentioned shortcoming of existing magneto.The slotless permanent magnet motor that the present invention proposes adopts a kind of new stator structure; The outstanding advantage of the stator structure of this motor is: shortcomings such as no above-mentioned slot effect, magnetic hysteresis loss, eddy current loss, magnetic saturation, and its load efficiency height, but stepless speed regulation, accelerating performance is good; Overload capacity is big; Volume is little; Operate steadily, torque ripple is little; And manufacturing process is simple.
The technical solution adopted for the present invention to solve the technical problems is: a kind of slotless permanent magnet motor is provided, comprises stator module, it is characterized in that:
Described stator module comprises supposition, iron core, stator winding, and described supposition is sleeved on the outside of described iron core, and described stator winding wiring is in the outside of described supposition; Described supposition is made of insulating material.
Described stator module also comprises trim ring, and described trim ring is sleeved on an end of described stator winding, and described supposition and described stator winding are fixed on the described iron core.
With described trim ring described stator winding is fixed on after described supposition goes up, in a vacuum glue embedding jail.
The insulating material of the sub-usefulness of described supposition is an epoxy resin bonded fiber.
Improvement place of the present invention is on stator module, groove and tooth on original stator core stamping sheet have been cancelled, replace supposition and the iron core of annular, suppose that son adopts insulating material to make, to suppose that son is sleeved on the improved stator core, at the stator that still forms trough of belt in shape, but whether the trough of belt part makes of metal, but make of insulating material, can not produce shortcomings such as slot effect that metal stator brings, magnetic hysteresis loss, eddy current loss, magnetic saturation.During wiring, still by original wiring method, have winding groove motor mode to connect up by common on supposition, having kept has the be evenly distributed advantage of symmetry of groove motor windings, torque ripple is little during use, and is good than the simple quality of technology of tubular coiling or sleeve shaped winding method.
In sum, the present invention has cancelled groove and the tooth on the stator core stamping sheet, replaces insulation supposition, thereby has solved several common issue with that the groove motor is arranged---slot effect, magnetic hysteresis loss, eddy current loss, magnetic saturation effectively.Load efficiency height of the present invention, but stepless speed regulation, accelerating performance is good; Overload capacity is big; Volume is little; Operate steadily, torque ripple is little; And manufacturing process is simple.

Embodiment
The improvement of present embodiment slotless permanent magnet motor is mainly on stator module.As Fig. 1, Fig. 2 is the stator module structure chart of this practical slotless permanent magnet motor, stator module comprises supposition 5, iron core 6, stator winding 7, described supposition 5 is sleeved on the outside of described iron core 6, and described stator winding 7 is routed in 5 outsides of described supposition.Described supposition 5 usefulness insulating material epoxy resin bonded fibers are made.As Fig. 3 is the stereogram of supposition 5, is the stereogram of iron core 6 as Fig. 4.
Stator module also comprises trim ring 8, and described trim ring 8 is sleeved on an end of described stator winding 7, and described supposition son 5 and described stator winding 7 are fixed on the iron core 6.
After with described trim ring 8 stator winding 7 being fixed on described supposition 5, glue embedding jail in a vacuum.
The present invention has cancelled groove and the tooth on original stator core stamping sheet, replace the supposition son 5 and the iron core 6 of annular, suppose that son 5 adopts insulating material to make, to suppose that son 5 is sleeved on the improved stator core 6, at the stator that still forms trough of belt in shape, whether but the trough of belt part is made of metal, but makes of insulating material, can not produce shortcomings such as slot effect that metal stator brings, magnetic hysteresis loss, eddy current loss, magnetic saturation.During wiring, still by original wiring method, have stator winding 7 groove motor mode to connect up by common on supposition 5, having kept has the be evenly distributed advantage of symmetry of groove motor windings, torque ripple is little during use, and is good than the simple quality of technology of tubular coiling or sleeve shaped winding method.
Its construction technology is: will suppose that son 5 is installed on the stator core 6, winding 7 is had by common that groove motor mode connects up, shaping on supposition son 5, fixing at sub 5 overcoats of supposition then with trim ring 8, carry out colligation again, guarantee colligation after the external diameter peak be not more than the sub-diameter of supposition; Fix with the embedding of anchor glue in a vacuum then.Three phase terminals and " Y " put respectively from drawing the groove separately; It remains in the drag cup outside.Lead-out wire is from the axial outlet of winding overhang.Hall lead-out wire A, B, C ,+5V, 0V color be respectively red, yellow, blue, white, black.After the embedding, carry out high temperature ageing, timeliness, be worked into size at last.
