Abstract
A ventilation cooling structure for the end portion of a coil comprises a stator iron core, unit coils, cushion blocks, polyester fiber and glass filament interwoven bands and polyester fiber and glass filament ropes. Each cushion block is arranged between an upper layer unit coil and a lower layer unit coil on the end portion of the coil, each polyester fiber and glass filament interwoven band is bound around the upper layer unit coil and the lower layer unit coil on the end portion of the coil, and each polyester fiber and glass filament rope is bound around the portions, closer to the end portion of the coil, of the upper layer unit coil and the lower layer unit coil. The ventilation cooling structure for the end portion of the coil can effectively restrict the temperature rise of the end portion of the coil, and plays an important role in preventing the coil from loosening.
Description
Technical field
The present invention relates to machine field, especially relate to the end winding ventilation cooling structure of high-voltage alternating similarities and differences step motor.
Background technology
High-voltage alternating is different, in the loss of synchronous motor, stator copper loss is to be formed by the coil resistance power loss, show with form of heat, for this effective cooling to coil is to prolong the insulating material life-span, improve the important means of running reliability of motor, carry out heat exchange by the convective heat transfer with coolant fully with the end winding of noncontact face unshakable in one's determination, play and stator core radial ducts same function in the gap between the coil part, can effectively control the end winding temperature rise.
Motor is in load load change process, and it is three-dimensional mobile that the electromagnetic force on the coil impels coil to produce, and the position of end wiring, mode play long-term fixedly reliability can not substituted role, and the present invention puts forth effort to improve.
Summary of the invention
The objective of the invention is effectively to improve the end winding ventilation cooling structure of air duct cooling effectiveness by improving wiring position, end and mode.
The present invention is achieved in that a kind of end winding ventilation cooling structure, comprises stator core, unit wires
Circle, cushion block, wash glass interweave band, wash the glass rope, it is characterized in that: between the unit coil of end winding levels, be provided with cushion block, be banded with on it and wash the glass band colligation that interweaves, be banded with in distance end winding closer locations and wash the glass rope.
Further, the described glass band that interweaves of washing adopts forward the snap close mode to carry out continuous colligation; The described glass rope of washing adopts " ten " word interleaved mode to carry out continuous colligation.
The present invention can control the temperature rise of end winding effectively, and to preventing the loosening important function that played of coil.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: 1, stator core, 2, coil, 3, cushion block, 4, wash the glass band that interweaves, 5, wash the glass rope.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
A kind of end winding ventilation cooling structure, comprise stator core 1, unit coil 2, cushion block 3, washing glass interweaves and is with 4, wash glass rope 5, it is characterized in that: between the unit coil of end winding levels, be provided with cushion block 3, can use and wash the glass bale of cotton 3240 or thermal expansion felt, and thickness is done correspondingly to adjust according to reality, then interweave and be with the 4 forward continuous colligations of bayonet type with washing glass, adopt the continuous colligation of " ten " word interleaved mode in distance end winding closer locations with washing glass rope 5, cooperatively interacting between the said structure satisfied the requirement of gaseous exchange heat exchange greatly, guaranteed again the reliability of anti-loose structure simultaneously.
