ROTARY DRIVER FOR TUBULAR BODY

摘要: PURPOSE:To obtain a rotary driver effective for driving of tubular body by constituting the stator in which pair poles mounted on ring type first and second yokes provided with coils are disposed oppositely permanent magnet rotor interposed between poles. CONSTITUTION:Upon application pulse voltage coil 21, flux is induced yoke 11 to excite 13 31 rotates according outer peripheral 13a, 13b an inner pole 13c. Upon subsequent 22, 12 17 excited. Consequently, 17a, 17b 17c. When power fed alternately sustains rotation. other rotors 32, 33, 34 rotate similarly, interlocked pinion 35 cylinder 40 driven.
