Technical field

This application involves a kind of armatures of motor, more particularly to the armature structure of the motor with insulation holder, Above-mentioned insulation holder between each other and is wound in above-mentioned armature core to the multiple busbars being disposed on the outside of armature core Coil carries out insulation holding.

Background technique

For example, (being turned in the three-phase alternating currents motor such as 3-phase brushless motor and three-phase linear motor by armature and movable member Son) constitute, wherein above-mentioned armature by the armature core being made of stacked steel plate be arranged side by side it is multiple form, above-mentioned movable member with Above-mentioned armature is oppositely disposed and is equally made of stacked steel plate.In addition, above-mentioned armature core is made of coil and insulation holder, Wherein, above-mentioned coil is wound in the pole teeth portion periphery of armature core, and above-mentioned insulation holder is laminated in above-mentioned electricity in arc-shaped Multiple busbars on the outside of armature core are supported, and to carrying out insulation holding between above-mentioned busbar.

As by the method for holding of insulating securely between multiple above-mentioned busbars, existed in the past and insulation holder is set Method (referring to patent document 1), above-mentioned insulation holder are configured to keep multiple above-mentioned busbars being radially laminated, And have between busbar from base portion side circular divider wall parts outstanding in the axial direction, creepage distance is (along dew The distance appeared) greatly than busbar space length (shortest distance) to each other, in addition, there is also following methods (referring to patent Document 2): the holding member that setting keeps multiple cyclic annular bare conductors in same heart shaped insulation, and by main part and tubular protrusion structure At above-mentioned holding member, wherein aforementioned body portion is respectively for above-mentioned cyclic annular bare conductor insert, and above-mentioned tubular protrusion is by from above-mentioned The side of main part covers above-mentioned cyclic annular bare conductor along above-mentioned cyclic annular bare conductor protrusion insertion hole outstanding, is made by resin It states main part and above-mentioned tubular protrusion is integrally formed.

Summary of the invention

However, in the method for above patent document 1,2, it is each insulate holder in order to so that creepage distance (along exposed surface Distance) mode bigger than the space length (shortest distance) of busbar to each other constitute the insulation of busbar to each other, use The main method obtained by distance designs the insulation of busbar to each other.Therefore, it is necessary to operation voltage correspondingly ensure with Comparable distance, and processing high voltage motor in, not can avoid enlargement problem.

In order to cope with the above problem, exist between insulation board is continuously clipped in busbar as described in Patent Document 3, And above-mentioned insulation board, busbar and holder are carried out by affixed component by insulating properties bonding agent each other.However, these Component will increase the adhering processes of insulation board, need huge burden on the fold of the plate after stickup, the management of skew.

The application makees to solve above-mentioned this technical problem, its purpose is to provide a kind of motor, by will be exhausted Edge holder is arranged to new construction, without ensuring the busbar to each other by the way that space length and creepage distance are equidistant Insulation can be constituted very compactly in the motor for handling high voltage, and assembling procedure and management are simple and cheap.

The armature of motor disclosed in the present application includes armature core, and above-mentioned armature core is arranged side by side at certain intervals； Insulate holder, and above-mentioned insulation holder carries out insulation holding to each coil for being wound in above-mentioned armature core；And it is multiple Busbar, multiple above-mentioned busbars stackings are configured at the outside of above-mentioned armature core, and be wound in the every of above-mentioned armature core The terminal of a coil is electrically connected, and above-mentioned insulation holder is made of coiling pipe portion and busbar supporting part, wherein above-mentioned bobbin Portion plays a role as the winding frame of above-mentioned coil, and above-mentioned busbar supporting part carries out insulation branch to above-mentioned busbar to each other It holds, above-mentioned busbar supporting part has busbar wall, and above-mentioned busbar wall is clipped in above-mentioned busbar to each other and by each busbar It is electrically isolated, constitutes stage portion along the stacking direction of busbar in above-mentioned busbar wall, above-mentioned stage portion is in busbar and busbar Stacking direction between wall along the longitudinal direction of busbar and iron core is formed with clearance portion, including insulating boot, and above-mentioned insulating boot exists Above-mentioned busbar is loaded in the state of above-mentioned busbar wall, above-mentioned clearance portion is made up from outside, and to above-mentioned remittance Stream item is kept.

According to the application, the armature structure of following motor can be obtained, though insulating coating is not implemented to busbar, or It is to also ensure that space length, creepage distance, and be able to achieve small-scale structure even if in the motor in processing high voltage.
