ABSTRACT:
A synchronous motor is employed to orbit one end of a stirring rod the other end of which is suspended by a flexible diaphragm in a liquid filled container. The synchronous motor includes a stator connected to a source of regular alternating current and a cylindrical permanent magnet rotor. A drive plate is connected across one end of the rotor. The stirring rod is received in an eccentrically located aperture in the plate so that one end of the rod is driven in a circle. The motor is connected to a mounting plate on the cap of the container by a pair of threaded studs. Springs surround each of the studs so that the distance between the motor and the cap can be altered by screwing up or down on a pair of wing nuts received on the studs. The diaphragm acts as a fulcrum for the stirring rod so that the linear velocity of the orbiting free end of the rod can be controlled by altering the distance between the motor and the cap. The device is relatively easy to clean and generates little heat compared with that of a magnetic stirrer.
