PURPOSE:To eliminate the nonuniformity of pole positions due to increased number of phases as well as to easily perform the winding work for the subject stepping motor by a method wherein the magnetic poles the number thereof is an integer times of odd number are provided on a stator core and the poles are excited successively by jumping over one or more of the adjoining magnetic poles. CONSTITUTION:In the case when the K is consisted of 1 or more of integer and the (n) is consisted of 2 or more of integers, K(2n+1), for example, 10 magnetic poles A-K are arranged as follows for example. The 1st and the 6th phases to the magnetic poles A and F, the 2nd and the 7th phases to the magnetic poles B, and H, the 3rd and the 7th phases to the magnetic poles E and K, the 4th and the 9th phases to the magnetic poles G and B, and the 5th and the 9th phases to the magnetic poles G and B, and the 5th and the 9th phases to the magnetic poles J and D. These phases are wounded in the bifilar winding respectively and the magnetic pole to be excited next is arranged at the position jumping over the adjoining magnetic pole. |
