Abstract

PURPOSE: To obtain linear motor of stable quality through a simple method, by making the flowing widths of magnetic field of yokes perpendicular to the moving direction of a moving member, unequal to each other in the moving direction of the moving member.
CONSTITUTION: When a prescribed current is caused to flow through a coil 5 on a bobbin 4, a moving member 6 supported on guide bars 7, 7 is moves along a yoke 2A the due to the interaction between the current and a magnetic field generated between the yokes 2A, 2B. Since the magnetic field flowing width ML2 of both the end portions 9, 9 of the yokes 2A, 2B is made larger than that ML1 of the central portions 8 of the yokes, a larger quantity of magnetic flux is produced in the end portions 9, 9 and the acceleration of the moving member 6 in starting and its deceleration in stopping are efficiently performed. This results in stabilizing the quality of a linear motor with an easily manufacturable construction.
