1.1 The rotor or rotor core should be thermally sleeved on the shaft. In the production and manufacturing of motors, the main function of thermal sleeve equipment is to promote the integration of the rotor, thereby ensuring that the motor's rotor reaches a certain strength. However, it can be seen in actual production that if the rotor generates slight heat, it will cause a large gap between the iron core and the rotating shaft, causing an imbalance in the air gap. In the vibration of the motor, the noise pollution is relatively large. . However, these phenomena are not visible, so operators can easily ignore them.
1.2 The aging of the welding machine base must be thorough. Insufficient aging of the welding machine base is the main cause of deformation. Even if this phenomenon occurs, it will not cause any operational failure problems in a short period of time. Normally, it will occur within half a year. Only within can you discover it. Therefore, the inspection work is relatively difficult. Specifically, the variation in coaxiality is also an important factor affecting motor vibration. The degree of damage to the bearing can be determined from the intensity and frequency of the noise.
1.3 Paint dipping. The so-called paint dipping usually refers to the paint dipping of windings. This phenomenon is not very obvious in actual production and manufacturing. If the quality of the dipping paint is not up to standard, moisture will be absorbed and the insulation strength will be reduced. Moreover, the winding is not easy to dissipate heat. During long-term operation, the temperature will rise and the insulation equipment will be damaged.
1.4 Iron core
The efficiency of the motor is easily affected by the quality of the core, including power parameters, noise and other factors. Poor quality of the iron core means that the pressure is too loose and the consumption of iron is relatively large. If the temperature continues to rise, burrs will cause serious harm to the insulation equipment and shorten the service life of the winding. In severe cases, a certain amount of electromagnetic noise will be produced, causing the motor to run out of balance.
1.5 Binding the ends of the formed windings For the formed windings, the ends must be tightly tied, and an appropriate amount of space must be left. This is mainly to avoid damage to the windings when starting the motor and ensure the heat dissipation effect. Reach the highest. For this link, a typical representative is Germany. In the production and manufacturing of motors, the binding work of windings will never be ignored.
1.6 Insert the rotor
During the operation of the motor, when rolling the bearings, it is necessary to install bearing end caps on both ends of the rotor to avoid damage to the bearings. Motors with appropriate electrodes do not allow excessive gaps. Therefore, relevant staff need to pay more attention to the rotor insertion of the motor.
1.7 Welding of copper bar rotor The welding requirements of copper bar rotor are relatively strict. Usually it needs to be carried out in a certain state, and the state cannot be changed. Otherwise a diamond shape will form.
1.8 Bearing assembly When performing bearing assembly work, the most important thing is to maintain a clean assembly environment. Operators cannot wear gloves. If it is a sliding bearing, the staff needs to pay more attention. But if it is a rolling bearing, it needs to be coated with a layer of grease.
