BIAXIAL SYNCHRONOUS REVERSE DRIVE MOTOR

PURPOSE:To provide a biaxial synchronous reverse drive motor in which two rotors can be synchronously reversed stably at high speed through a predetermined gap by solving the problem of unbalance load in the radial direction due to attraction of magnetic couplings between different poles of two rotors. CONSTITUTION:Two rotors 3A, 3B provided with permanent magnets on the outer periphery thereof are arranged through a predetermined gap (t) with the different pole faces opposing and attracting each other thus constituting a magnetic coupling. Armatures 7, 8, 9, 10 are arranged through the predetermined gap on the outer periphery of respective rotors which are rotated reversely by the spatial moving fields of the armatures. In such biaxial synchronous reverse drive motor, a pair of magnetic bodies 5A, 5B producing the attracting force in the direction opposite to that of the magnetic coupling between two rotors are fixed oppositely to the opposing face of two rotors through a predetermined gap therefrom.
