Abstract: A linear motor is operatively connected to operate a pair of axially aligned compressors. A pair of axially spaced and oppositely wound coils are mounted to a cylindrically shaped coil form movably connected to drive the aligned compressors with the coils serially connected to a single phase A.C. power source. A pair of spaced annular magnets provide a pair of annular poles of opposite polarity spaced immediately adjacent to the pair of coils while an outer annular flux conducting member connects the outer radial portions of the annular magnets. One embodiment spaces the pair of compressors at opposite axial extremities of the linear motor construction while a second embodiment centers the compressors within the movable coil form.
