鼠笼电机转子质量直接影响电机的性能。立式压铸工艺是工业电机常用的生产工艺，转子压铸熔杯的质量及工艺温度控制是顺利制造转子、保证质量的关键。无纸杯压铸工艺取消了石棉纸杯，杜绝了石棉纸压入转子的可能，配合大比压压铸设备有效地提高了电机转子的内在质量，更好地满足超高效电机的性能要求。

Rotor in squirrel-cage induction motor has direct effect on the motor performance. Vertical die casting process is one of the common techniques to produce industrial motors. The key to manufacture qualified industrial rotors smoothly depends on the casting cup and the precise temperature control in the process. A die casting melting cup without asbestos for vertical motor rotor production is designed. With this technology, no asbestos will be pressed and mixed into rotors. Meanwhile, using high pressure die casting equipment, the rotor quality can be improved effectively to satisfy the performance requirements of ultra high efficiency motor.
