Linear pulse motor

Abstract

Abstract PURPOSE:To readily manufacture the linear pulse motor by disposing a permanent magnet magnetized in multiple poles alternately at a stator, and providing poles at a plurality of intervals at a rotor and winding exciting coils at the yokes between the poles. CONSTITUTION:The stator 11 is formed of a base 12 and permanent magnet 13 magnetized alternately and bonded fixedly on the upper surface of the base 12. The rotor is formed of poles 15A, 15B, 15C magnetically connected with yokes 16A, 16B, and exciting coils 17A, 17B wound on the yokes 16A, 16B respectively. When the rotor is moved, the currents in the coils 17A, 17B are controlled, thereby controlling the polarities of the poles 15A, 15B, 15C. Since the permanent magnet is used instead of the stator teeth, the manufacture of the motor can be readily conducted, and the linear pulse motor can thus be manufactured.
