Benefits of technology

The technical feature described by this patented technology relates to an electrical pneumatic compression machine that uses heat from both the motors' stator coils (their internal parts) for better performance at higher speeds when used alone or together. It eliminated any extra external devices like water circulation systems needed due to lack thereof. By doing away with these things, there was no longer too much weight being placed onto them during operation. Overall, this design made up more efficient and effective machines possible because they didn’t require expensive materials themselves.

Problems solved by technology

This technical problem addressed in this patented text relates to improving the efficiency or performance of electrical compressed air systems by reducing their temperature during startups while still maintaining stability over time.

Abstract

The invention discloses an electric air compressor with a motor rotor cooling system. The electric air compressor comprises an impeller, an impeller back plate cover plate, a thrust bearing, a bearingcover and a motor which are sequentially arranged in the axial direction, an impeller air inlet hole is formed in the impeller, a back plate cover plate cooling hole is formed in the impeller back plate cover plate, a thrust bearing cooling hole and a bearing cover cooling hole are formed in the thrust bearing and the bearing cover respectively, air passes through holes in the impeller, the impeller back plate cover plate, the bearing and the bearing cover to reach between the motor rotor and a motor stator, and finally is discharged from a motor rear end cover. The electric air compressor effectively cools the motor rotor and does not need to be provided with an additional cooling device, so that the manufacturing cost and the use cost are reduced, and the assembly space is saved.
