| description | PROBLEM TO BE SOLVED: To attain downsizing and high output of a stepping motor by axially disposing the first and second coils on a cylindrical magnet whose outer peripheral surface is divided into (n) circumferentially and different poles are polarized alternately, and facing the first and second inner and outer poles against outer and inner peripheral surfaces of both ends of the magnet. SOLUTION: The outer peripheral surface of a cylindrical magnet 1 is divided into (n) circumferentially, the south pole and north pole are polarized alternately, and an output shaft 7 is pressed into a fitting part 1w for forming a rotor. A cylindrical coils 2, 3 are disposed so as to be concentric with and axially- sandwich magnet 1. The first and second outer poles are formed on the front end of the respective outer tube of the first and second stators 18, 19 formed out of outer and inner tubes, and the first and second auxiliary stators 21, 22 are fixed on the inner tubes of the respective stators 18, 19 for forming the first and second inner poles. It is thus possible to reduce the diameter and length of the step motor for downsizing and high output. |
