PURPOSE:To eliminate the necessity of a running body such as a tape or belt, by engaging a rotor with a hollow support shaft supported between two pais of stepped pulleys, providing a stator for rotating the rotor in a specific state, and passing a high-frequency current through the stator. CONSTITUTION:The base part of a hollow support shaft and a protruding support shaft 2' passing protrusively through the hollow support shaft are supported between mutually adjacent left and right stepped pulleys 8, 8, 9 and 9, thereon. A rotor (R) is engaged with the hollow shaft, and a stator (S) is provided to rest at a position eccentric to the rotor (R). A high-frequency current is passed through the stator (S). |
