Abstract: A rotor for an electromagnetic clutch assembly includes a substantially cylindrical main body extending from a first end to a second end. The first end of the main body is configured to engage an armature of the electromagnetic clutch assembly and includes a first flange formed around a circumference thereof. The second end of the main body includes a second flange formed around a circumference thereof. One of the first flange or the second flange has a non-uniform cross-sectional shape as the one of the first flange or the second flange extends circumferentially around the main body, wherein the cross-sectional shape of the one of the first flange or the second flange taken through a plane extending parallel to an axis of rotation of the main body.

Abstract: An oil separator for a compressor is shown, wherein an oil separating efficiency is maximized and a material cost, a weight, and an assembly time are minimized.

Abstract: An electromagnetic clutch includes an armature plate connected to a shaft and being movable axially with respect to the shaft, a rotor being rotatable relative to the shaft, and a plurality of electromagnetic coils, wherein when at least one of the electromagnetic coils are energized a magnetic field will draw the armature plate into contact with the rotor such that the rotor and the shaft are rotatably connected. The magnetic coils are connected to a common power supply providing the magnetic coils a common, non-varying, voltage and a master control switch selectively supplies power from the power supply to the magnetic coils. The magnetic coils are connected to one another in parallel and each coil has a switch to allow each coil to be energized independently of the other coils, individually or in any combination to provide a magnetic field of varying strength.
