Abstract

The utility model discloses a motor insulation skeleton in two hall grooves in area, this motor insulation for the skeleton insulating material form by mould one shot forming preparation, the motor insulation skeleton is equipped with the groove that holds the hall element PCB board, end structure embedding motor core inslot under the motor insulation skeleton. The utility model has the advantages that guarantee the uniformity of hall element mounted position, offer convenience for drive debugging link simultaneously, the efficiency of the motor assembly is improved, be convenient for assemble greatly in batches. The research and development design cost has been saved simultaneously, insulating skeleton has two grooves, can satisfy the requirement of the two -way rotation of motor.

Description

The electrical machine insulation skeleton of the double; two Hull cell of band

Technical field

This utility model relates to a kind of brushless single phase motor technical field, particularly to a kind of electrical machine insulation skeleton with double; two Hull cells。

Background technology

Brushless single phase motor in the market, generally adopts placement working of plastics in groove to be used for fixing Hall element, and its installation method is for be first fixed on pcb board 2 by Hall element 1, then is installed on the working of plastics being placed in motor stator slot by pcb board。General installation method is shown in shown in Fig. 1 and Fig. 2。This structure includes Hall element 1, pcb board 2 and working of plastics 3, and this kind of structure generally has problems with:

1) owing to the machining accuracy of working of plastics 3 is relatively low so that there is certain deviation the position being placed in motor slot, after the pcb board with Hall element is put into, position also can should have deviation mutually。This position that directly results in Hall element sensing magnetic pole is different, drives debugging to bring great difficulty in motor during batch production, and motor concordance cannot ensure；

2) when motor stator core is through leaching insullac or after utilizing insulation framework to process, then working of plastics die sinking link is individually increased, inefficient and motor R&D costs can be increased；

3) utilizing working of plastics 3 to fix Hall element 1 can only make motor one direction rotate, and the shape needing change working of plastics to ask motor to reversely rotate, from new die sinking。This place that the application needs improve emphatically just。

Utility model content

Technical problem to be solved in the utility model is to provide for a kind of Hall installation accuracy that ensures, raising installation effectiveness, the electrical machine insulation skeleton of the double; two Hull cell of band of the positive and negative bidirectional rotation of energy。

In order to solve above technical problem, this utility model provides a kind of electrical machine insulation skeleton with double; two Hull cells, this electrical machine insulation skeleton insulant is made by mould one-shot forming and is formed, electrical machine insulation skeleton is provided with the groove holding Hall element pcb board, and electrical machine insulation skeleton lower end structure embeds in electric machine iron core groove。

The groove of described accommodation Hall element pcb board, quantity is two, is used for ensureing the positive and negative bidirectional rotation of motor。

Superior effect of the present utility model is in that:

1) concordance of Hall element installation site is ensured, simultaneously for driving debugging link to offer convenience；

2) improve motor efficiency of assembling, it is simple to high-volume assembling。Save R & D design cost simultaneously；

3) insulation framework is with two grooves, can meet the requirement of motor bidirectional rotation。
