Mechanical characteristics of motor parts
The machine tools and cutting tools used in the machining of motor parts are not much different from those of general machine manufacturers. However, due to the influence of the structure and electromagnetic performance of the motor, the following characteristics must be paid attention to when machining the motor components:
● The air gap has a great influence on the performance of the motor. When formulating the machining plan of the motor components, the coaxiality of the components and the reliability of the mating surfaces should be fully paid to ensure the size and uniformity of the air gap.
●Compared with ordinary machine parts, the structural rigidity of the motor base and end cover is poor, and deformation or vibration is easily generated during clamping and processing, which affects machining accuracy and roughness.
●For parts with integrated materials, such as stators, rotors, commutators and slip rings, it is not possible to use coolants such as engine oil or soap liquid during machining. Metal chips should not fall into the insulation to avoid insulation. Deterioration; more should prevent chips from getting stuck in the insulation material, causing insulation damage accidents.
● For magnetically conductive parts, the cutting stress should not be too large to avoid lowering the magnetic permeability and increasing the iron loss.
