Abstract
A combined motor and rotational cell for use in an apparatus for measuring components in a gas colorimeter, smoke meter, etc. by utilizing light absorption or fluorescence. The combined motor and rotational cell has a motor with a plurality of magnetic poles around the periphery of thereof, at least one diametrically extending partition wall extending across the hollow interior for defining at least two compartments in the rotor, and optically transparent windows on the outside of the motor closing the compartments. A plate-shaped chopper is provided on one side of the rotor having a plurality of apertures therein equidistantly spaced around the chopper. A casing surrounds the rotor and supports the rotor shaft in bearings and has a plurality of coils around the inside of the peripheral wall opposed to the magnetic poles on the rotor. Apertures are provided in the opposite end walls of the casing aligned with the compartments in the rotor for passing light through the casing and the rotor.
