- Factors Affecting Temperature Rise During Manufacturing
Purity and parameter control of cast aluminum rotor aluminum
For aluminum for cast aluminum rotors, on the one hand, it is the quality control of aluminum procurement, and on the other hand, it has a direct relationship with the device for melting aluminum in the process of casting aluminum. Some companies use ceramic tong pots, which effectively ensure the purity of aluminum in the process of casting aluminum; but some companies use cast iron tong pots. In this way, aluminum is cast. In each batch of rotors, some rotors always use the last aluminum in the pot. The poor purity of aluminum in the liquid is directly manifested in the large resistance of the motor during the inspection test, because the excessive iron content leads to an increase in the leakage flux of the tank.
The rotor casting aluminum process parameters mainly include the core preheating temperature, the molten aluminum temperature, the pouring speed, the rotational speed and pressure of the centrifugal pouring, etc. These parameters have certain differences among different motor manufacturers, and are also relatively key and confidential control parameters for the manufacturers. Ms. Shen has visited a low-pressure aluminum casting company. The company is well-equipped and the quality of rotor casting is very good. However, high-level confidentiality measures have been taken for the process parameters of the process, and outside visitors cannot see the specific details at all. content.
Rotor Cast Aluminum Defect Control
Use the broken bar inspection device to check whether the rotor has defects such as thin bars, broken bars, shrinkage holes, shrinkage porosity and air holes. For the rotor with serious defects in the rotor, the rotor will show obvious bluing phenomenon when the motor is running, and the more serious rotor aluminum will melt and flow out.
Motor manufacturing is a manufacturing project that strives for perfection. The same design scheme is produced by different motor manufacturers and will have completely different effects; different motor manufacturers have their own unique advantages in different process links. The advantage of being a high-quality motor is the call for the quality of motor products under the new market conditions.
