This study applies the spherical stepping motor the authors developed to the driving device of a stirrer and develops a proto-type stirrer. The developed stirrer is composed of a rotor, a stator, a control PC, an electric-magnet excitation circuit, and a power supply. The rotor is composed of double spherical shell in order to contain liquid in its inner spherical shell. Totally 91 permanent magnets are arranged in the rotor. On the other hand, 80 electro-magnets are arranged on the stator. The applicability of the stirrer to material production is evaluated by stirring experiments.
