Step motor with double coil in a plane

摘要: The invention concerns a step motor with two magnetic induction coils (9, 10) and rotor (1) consisting of permanent magnet n poles, the yoke parallel planar plates (2, 3) linked by spacers (7, 8) around which said are arranged, coaxial orifices (13, 14) provided in defining space cylindrical appearance wherein is placed, each plate including teeth (5, 6) oriented substantially perpendicular to its plane, direction other (3, 2), arranged at periphery through passes, coming from interlocking form cage housed (1). characterised that one (3) comprises n/2 teeth, whereas second (2) only n/2-1 circuits associated coil comprising likewise respectively.
