Description
Technical field
It the utility model is related to a kind of support of motor and be advantageous to electronic using the frame motor, particularly one kind
The support and the motor using the support of machine ventilation, belong to motor technology field.
Background technology
Big-and-middle-sized threephase motor, especially high-speed motor, turn into new development in pipeline compressor electric motors
Direction.At present, the aeration structure as motor, angle is passed through between the former and former of the support of conventional slow-speed motor
Steel, square steel or round steel welding are to form entirety, while perforate is used to divulge information on the former of both ends, to form cooling end stator
The wind path of coil.
Said structure support stiffness is good, using more in conventional slowspeed machine, but when motor speed is higher, stator iron
Core back（Stator core peripheral side wall in other words）The blast of return air and wind speed are excessive, so that end turn return air is obstructed, end
Portion's stator coil cooling effect is poor, and temperature rise, which uprises, ultimately causes the fixed subcoil insulating lost of life, reduces the use of motor
Life-span.
The content of the invention
Goal of the invention of the present utility model is：For above-mentioned problem, there is provided one kind is advantageous to motor ventilation
Support and using the support motor, the utility model is simple in construction, practical, disclosure satisfy that the rigidity needed for support
It is required that the wind path of cooling end stator coil and the wind path for cooling down stator core are non-interference independently of each other, be advantageous to motor
