A rotary device is disclosed that includes a rotor comprising a main body and plurality of protrusions extending radially from the main body. At least a pair of voids are provided adjacent to each other in the main body of the rotor between each adjacent pair of the plurality of protrusions, and each pair of voids is spaced from each adjacent pair of voids by a distance greater than that between each adjacent void in each pair of voids.
