US 2019/0154037 A1 · Compressor Having Counterweight

Abstract

A compressor may include a compression mechanism, a motor, and a counterweight assembly. The motor assembly is drivingly engaged to the compression mechanism and includes a rotor driving a driveshaft. The rotor drives the driveshaft. The counterweight assembly is mounted axially onto the driveshaft of the motor assembly and has a first laminated stack of plates that includes a plurality of first plates and a plurality of second plates. Each first plate defines a first polygonal-shaped aperture that has a plurality of sides. Each second plate defines a second polygonal-shaped aperture that has a plurality of second sides. The first sides of the first polygonal-shaped apertures are rotationally misaligned with the second sides of the second polygonal-shaped apertures.
