Motor Frames and Motors

Abstract

The invention provides a motor base, which is characterized in that it comprises a driving end base (31) and a non-driving end base (32), and the driving end base (31) and the non-driving end base (32) are connected by bolts. connected. The present invention also provides a motor comprising the aforementioned motor base. The two parts of the split frame and the stator are installed separately, so that the stator does not need to pass through the inner holes of the end connecting plates located at both ends of the frame, and the size of the inner holes of the end connecting plates does not need to be larger than the outer diameter of the stator core , to ensure the strength and manufacturability requirements of the base structure, and at the same time, you can choose to use a stator with a larger outer diameter to obtain higher output power.

Description

technical field [0001] The invention relates to a motor base and a motor. Background technique [0002] In a motor, higher output power often requires a larger outer diameter of the stator, larger dimensions, or the use of special design materials, which will lead to an increase in the material cost of the motor. [0003] In the general assembly process of the motor, the stator needs to enter the frame through the inner hole of the frame. For the existing frame size, increasing the outer diameter of the stator means that the frame needs a larger inner hole, which is very difficult without increasing the size of the frame. [0004] In addition, the increase in power will lead to more heat generation, which also means that a larger space is required inside the motor to meet the needs of the cooling air circuit inside the motor. Under the premise of keeping the size of the motor unchanged, the existing motor structure cannot meet the design requirements of the air circuit. ...

Problems solved by technology

For the existing frame size, increasing the outer diameter of the stator means that the frame needs a larger inner hole, which is very difficult without increasing the size of the frame

[0004] In addition, the increase in power will lead to more heat generation, which also means that a larger space is required inside the motor to meet the needs of the cooling air circuit inside the motor

Under the premise of keeping the size of the motor unchanged, the existing motor structure cannot meet the design requirements of the air circuit

[0005] When the motor design adopts IC36 or similar cooling methods, the air outlets are on the left and right sides of the motor drive end, which will cause the axial cooling air inside the motor to flow directly out of the motor, without effectively cooling the ends of the stator windings
