Abstract
The utility model relates to multi-level protection which is adopted for the insulation of a rectangular notch of a direct current motor armature iron core. An armature winding is arranged at an armature rectangular notch, protection devices are arranged at the armature rectangular notch, and the protection devices comprise a slot wedge and a slot cover plate which are sequentially arranged from the notch from inside to outside. Three layers of protection devices are arranged at the armature winding notch, and are sequentially the slot wedge, the slot cover plate and a non-latitude band, so that the protection strength of the armature winding is greatly enhanced, the armature winding is not flung from the rectangular notch, and the working stability of a motor is improved.
Description
Technical field
The utility model relates to a kind of rectangular notch insulation of direct current machine armature core and adopts multi-level protection.
Background technology
In existing direct current machine design manual and direct current machine handbook manufacture process,, generally adopt the pattern of slot wedge or groove cover plate for the armature winding of the rectangular notch of protecting armature core.But when running into the bigger direct current machine of rotating speed height or armature linear velocity, sometimes armature winding is thrown away from the armature rectangular notch, the armature winding of motor is damaged or burn, even whole motor is scrapped.
The utility model content
The utility model provides a kind of simple in structure in order to overcome the above problems, and improves the protective device of direct current machine armature winding protective capability.
The technical solution of the utility model is: described armature winding is arranged on the armature rectangular notch, and described protective device is arranged on the notch place of armature rectangular notch, and described protective device comprises slot wedge, the groove cover plate that sets gradually from the inside to the outside from notch.
Described groove cover plate external packets is established no latitude band; Described groove cover plate is embedded in the notch, and groove cover plate upper surface is lower than the notch upper surface, and groove cover plate upper surface is lower than notch upper surface 0.5-1mm.
The utility model has the advantages that: the utility model is provided with the three-layer protection device at armature winding notch place; be followed successively by slot wedge, groove cover plate and do not have the latitude band; greatly strengthen protection intensity to armature winding, armature winding can not thrown away from rectangular notch, improved the working stability performance of motor.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
1 is armature core among the figure, the 2nd, and slot wedge, the 3rd, groove cover plate, the 4th, no latitude band.
Embodiment
The utility model adopts multi-level protection in the rectangular notch insulation of armature core 1, comprises no latitude band 4 wrappings of slot wedge 2, groove cover plate 3 and the armature core outside of slot-open-section.
The utility model improves the armature rectangular notch by adopting the slot wedge structure pattern to add groove covering plate structure pattern, lower floor adopts 3240 slot wedges 2, the upper strata adopts 3240 grooves of thick 1.5mm to cover 3 plates, stays 0.5～1mm air air gap, and the armature outside uses 0.25 * 20 no latitude band 4 repeatedly to wrap two layers again.
