FAQ

1. Talking about the selection of the benchmark for the machining process of the motor rotor
     In the process of component processing, the uniqueness of the datum will effectively reduce the relative error, and it is also a very critical control point in the design and processing process.
   For the rotor part of the motor, the center hole of the end face is generally selected as the machining reference during the machining of the rotating shaft, which ensures the coaxial requirements of different cylindrical surfaces of the rotating shaft; for the shaft and the core hole of the rotor, the interference fit between the two ensures that the outer surface of the rotor and the shaft In the process of turning the outer surface of the rotor, the most ideal solution is to use the center hole of the shaft end as the machining reference.
   
   However, in the actual processing process, due to the limitations of the workpiece itself or processing equipment, it is often difficult to achieve the desire to use the same benchmark for multiple processing surfaces and multiple processes. In the process of motor production and processing, the dynamic balance of the rotor mostly chooses the bearing position as the rotation reference. When turning the rotor of large-scale motors, sometimes the bearing position is selected as the rotation reference. From a theoretical point of view, the bearing position is used as the reference, which is exactly the same as the motor running. It is also a reasonable choice to be consistent with the benchmark, but the smoothness of the support level and the normative relative position must be guaranteed. No matter how the datum is selected, the protection of the datum itself is particularly important. If it is not handled properly, the deviation of the processing size will lead to mechanical defects or failures of the motor product.
   
   Coaxial requirements in motor products
   
   Coaxial is a relative positioning concept for cylinders, which means that the central axes of two or more cylinders coincide. For motor products, the rotor part is a very typical multi-cylinder coaxial component. The coaxiality of the motor shaft extension, bearing position, rotor core position, rotor core cylindrical surface, and winding rotor motor collector ring position is the guarantee The necessary conditions for the conformity of the mechanical performance of the motor assembly; the mouth of the motor base and the iron core position should also be coaxial; when the motor is running, the cylindrical surfaces mentioned above should theoretically be coaxial to ensure that the air gap between the stator and rotor of the motor is sufficiently uniform .
   
   When the motor is in a static state, due to the radial clearance of the bearing and the actual weight of the rotor, the stator and the rotor are in a non-coaxial state. In view of this problem, the requirement of regularly rotating the rotor during storage is proposed for large-size motors to avoid Unnecessary damage to the bearing.
   
   In addition to the complete machine products, some process requirements are put forward for the deformation of the parts during the production and processing process and the storage process of the parts. The purpose is to reduce and eliminate the deformation of the parts that affect the assembly quality of the motor. The most important One of the contents is the control requirement of coaxiality.
   
   The low-frequency electromagnetic sound in motor products is the abnormal sound caused by the non-concentricity of the stator and the rotor. Under the limit state, there will be a problem of sweeping the stator and the rotor.
   
   In order to ensure the coaxiality control requirements of components, the selection of related component tolerances and the control of the processing process are particularly important. Under the same design scheme, some motors are balanced and quiet during operation, while others have different degrees of vibration and vibration. The root cause of noise is self-evident.
