A compressor of the type having vanes reciprocable along a rotor shaft through slots in a rotor under the guidance of stationary guide surfaces on the rotor, and a cylindrical mantle extending around the vanes and secured for rotation with the rotor, has the improvement that an electric motor rotor is provided around and secured to the exterior of the cylindrical space to save space and expense. The motor stator is secured to the inner side of a housing enclosing the motor rotor and the cylindrical mantle, and the housing has mutually opposed end portions in which the rotor shaft is journalled.
