A compressor may include a shell. A compression mechanism may be disposed within the shell. A drive shaft may be disposed within the shell and drivingly engaged with the compression mechanism. A motor assembly may be drivingly engaged with the drive shaft and may include a rotor and a stator. A plurality of magnets may be disposed within the rotor and may cooperate with the stator to create an electromagnetic field between the rotor and the stator. A counterweight assembly may be secured to the drive shaft and configured to dynamically balance the compression mechanism and secure the plurality of magnets within the rotor.

Compressor having counterweight assembly

A sound enclosure for enclosing a compressor assembly in an assembled state can include at least one cover piece, a shoe member, and a base. The shoe member can include a partial circumferential wall that projects upright from a generally planar portion. One of the partial circumferential wall or the cover piece has a projected portion. The other of the partial circumferential wall or the cover piece has a recessed portion. In the assembled state, the projected portion nests into the recessed portion. The base includes an outer contact area. The shoe member includes an outer perimeter. In the assembled state, the outer contact area is in contact with the outer perimeter of the shoe member.

Sound enclosure for enclosing a compressor assembly

A cup-shaped shield surrounds a counter weight on the lower end of a rotor of the refrigeration compressor. The shield advantageously restricts lubricant flow to the rotating lower end of the rotor whereby power consumption of the motor is reduced. The shield may be axially and/or rotationally limited by engagement with a lower bearing assembly. The shield may be used on a scroll compressor. The shield may also be used on a rotor without having a counter weight on the lower end thereof.
