Description

The coil holder of axial coiling

The utility model relates to a kind of coil holder of axial coiling, when this coil holder is made the coiling coiling, can form closely knit being wound on around the centre bore, to increase stator flux does and to increase the motor outputting torsion.

The motor stator coil holder structure of commonly using, as No. 273360 " fan motor structure " novel patent case of Taiwan patent announcement at 85 years 03 month 21 days bulletins of the Republic of China, it mainly is provided with upper pole piece 91, lower magnetic pole sheet 92 and is provided with a central siphon 93 by this coil holder 90 by a coil holder 90, establishes coiling gap 94 around coil holder 90 centre bores for coiling coil 95.This coil holder 90 articulates a rotor 96 by central siphon 93 and constitutes a motor, and at this moment, the magnetic pole of upper pole piece 91, lower magnetic pole sheet 92 is corresponding to the annular magnet 97 of this rotor 96; Because this coil 95 that is wound on the coil holder 90 is a contour ring body, therefore, the coil 95 that is wound in coil holder 90 by near the position of centre bore to away from central hole location, form uniform sparse distribution, because this coil turn is directly proportional with the magnetic flux that it is produced, therefore, desire produces under the bigger magnetic flux situation, need to increase coil turn, relatively, the height of this coil holder 90 or diameter need to increase, and the loop length of reeling also need increase, so, could increase the motor outputting torsion and promote the motor power output.

The purpose of this utility model provides a kind of coil holder of axial coiling, the coil holder of motor stator is reached by the gap that winds the line that constitutes communicating pipe that is communicated with two cards by first card, second card, this two card week acies spacing greater than in conjunction with two cards around coil holder communicating pipe, therefore, near more closely knit coil turn was arranged around coil holder communicating pipe, when passing to electric current, can produce bigger magnetic flux, therefore, can increase motor outputting torsion and also do not influence the carrying out of whole coiling work originally.

The purpose of this utility model is achieved in that a kind of coil holder of axial coiling, comprises coil holder, has first card, second card and connects communicating pipe of first card, second card, and this communicating pipe has centre bore; Form the coiling gap between the opposed inner walls face of this first card, second card; First pole piece is combined in the first card outside wall surface of this coil holder; Second pole piece is combined in the second card outside wall surface of this coil holder; It is characterized in that: form this coiling gap two cards weeks acies spacing greater than spacing in conjunction with the connection pipe end of two cards.

The two card opposed inner walls faces in this coiling gap of described formation and communicating pipe connect the position, angle, have at least one to connect the position, angle and form the skew wall face.

The opposed inner walls face of two cards in this coiling gap of described formation has at least an internal face to form the skew wall face, and forms spacing reduction gradually by all acies of card towards being communicated with pipe end.

The opposed inner walls face of described two cards and communicating pipe connect the position, angle, have at least one to connect the position, angle and form arc surface.

The opposed inner walls face of described two cards has at least an internal face to have two above cascaded surfaces, and connects the connection wall of this cascaded surface, and this connections wall is the skew wall face, this cascaded surface and connect wall by all acies of card towards the reduction gradually of connection pipe end spacing.

The connection wall of described this cascaded surface of connection is an arc surface.

Owing to adopt such scheme: can increase the motor outputting torsion.
