Abstract
The present disclosure relates to a low noise, compact rotary compressor configured to damp noise and vibration generated from internal components. The compressor may include a stator holder coupled to the stator and the pump, providing physical separation between the stator and the casing. The compressor may also include a pump holder coupled to the pump and the casing, providing physical separation between the pump and the casing. Additional damping components may be placed at various coupling points within and around the stator holder and/or pump holder. The suction line connection may also be configured to reduce noise and vibration. Aspects of the present disclosure may be applicable for reducing the noise and vibration in a number of fluid displacement devices and BLDC motors.
