Abstract
The utility model relates to a kind of wide-angle skewed slot motor insulation structure.The structure that the utility model is taked is: comprise groove tooth, chamfering, cylinder insulation, intercolumniation insulation, groove, motor stator.Insulation system is arranged in motor stator inner ring, motor stator is the cylinder that multi-disc motor stamping spiral is overrided to form, in the end of motor stator, the groove tooth edge of groove has chamfering, in motor stator groove, be wherein equipped with intercolumniation insulation, motor stator slot tooth is equipped with cylinder insulation.The utility model solves the insulation system problem of wide-angle skewed slot motor, this structure is ensureing that motor performance is impregnable while, efficiently solve damage in insulation between winding and lamination and winding takes off groove problem, be particularly suitable for wide-angle skewed slot motor and copper factor is high, draw ratio is little machine field.
Description
Technical field
The utility model belongs to a kind of skewed slot Insulation Construction Design for Electric Machines technology.
Background technology
Motor mounting space is required harsh at some aerospace field: the major diameter of motor is smaller.General direct current machine all needs motor lamination skewed slot, is conducive to like this reducing motor cogging torque, and be conducive to improving motor low-speed performance, we are referred to as wide-angle skewed slot motor this class motor.Wide-angle skewed slot motor uses conventional motors insulation system, there is following problem:
1, groove tooth and cylinder angle are right angle, and enamelled wire easy damaged or fracture during rule, cause the damage in insulation between motor stator winding and housing, and insulating resistance value is zero;
2, because helical groove dextrorotation angle is large, cause intercolumniation insulation distortion, during rule, coil is easily run out of or alters groove, causes empty load of motor electric current to increase.
Utility model content
The purpose of this utility model is: the insulation system proposing a kind of wide-angle skewed slot motor, replaces right angle by chamfering, and design the insulation of groove tooth, having stopped the insulating resistance value between each passage winding and housing is the problem of zero simultaneously.
The technical scheme that the utility model is taked is: described insulation system is arranged in motor stator 6 inner ring, described motor stator 6 is the cylinder that multi-disc motor stamping spiral is overrided to form, every sheet motor stamping endoporus is evenly distributed with the plane groove of several same specifications, plane groove even transition corresponding on adjacent motor stamping, in the inner ring of motor stator 6, form many equally distributed spiral helicine grooves 5 after multi-disc motor stamping spiral laminates, described insulation system is made up of groove tooth 1, chamfering 2, cylinder insulation 3, intercolumniation insulation 4; In the end of motor stator 6, groove tooth 1 edge of groove 5 has chamfering 2, in motor stator 6 groove 5, be wherein equipped with intercolumniation insulation 4, motor stator slot tooth 1 is equipped with cylinder insulation 3.
Preferably, the rounding size of chamfering 2 is determined by motor stator 6 outer annular diameter.
Preferably, cylinder insulation 3 is completely docile on groove tooth 1.
Preferably, the junction of cylinder insulation 3 and groove 5,2-3 millimeter in grooves 5 is inserted in cylinder insulation 3.
Preferably, intercolumniation insulation 4 is completely docile and obedient on groove 5, and is continuous annular structure.
Preferably, intercolumniation insulation 4 adopts polyimide film, the Kapton Tape that cylinder insulation 3 adopts.
The advantage that the utility model has is: this insulation system, not only solve in skewed slot motor wire-inserting, damage in insulation between winding and lamination and winding take off groove problem, and the insulating resistance value also stopped between each passage winding of wide-angle skewed slot motor and housing is the problem of zero;
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model better embodiment.
Embodiment
Below in conjunction with Figure of description, the utility model is elaborated, see Fig. 1, the structural representation of a kind of wide-angle skewed slot of the utility model motor insulation structure execution mode.Describedly insulate 3 by groove tooth 1, chamfering 2, cylinder, intercolumniation insulate 4, groove 5, motor stator 6 are formed.In the end of motor stator 6, groove tooth 1 edge of groove 5 has chamfering 2, the rounding size of chamfering 2 is determined by motor stator 6 outer annular diameter; In motor stator 6 groove 5, be wherein equipped with intercolumniation insulation 4, intercolumniation insulation is continuous annular structure, make its complete docile groove 5 wall when mounted, laying cylinder insulation 3 on motor stator slot tooth, cylinder insulation 3 is rectangle structure, be pasted onto on groove tooth 1 respectively according to the groove number of teeth, cylinder insulation 3 also inserts 2-3 millimeter in adjacent two grooves 5.Intercolumniation insulation 4 adopts polyimide film, the Kapton Tape that cylinder insulation 3 adopts.
The utility model achieves wide-angle skewed slot motor insulation structure, replaces right angle by chamfering, prevents the damage of enamelled wire during rule and fractures, the damage in insulation problem between winding and lamination; Intercolumniation insulating Design becomes continuous annular structure, adds the firm power of insulation, and when solving rule, coil is easily run out of or alters groove, causes the problem that empty load of motor electric current increases; Design the insulation of groove tooth, having stopped the insulating resistance value between winding and housing is the problem of zero simultaneously.
