Title:
LINEAR MOTOR DRIVING GEAR
Document Type and Number:
Japanese Patent JPS6430446
Kind Code:
A
Abstract:
PURPOSE: To obtain a driving gear without malfunction, by setting the short coil of a conductive member in a space between a coil and a core.
CONSTITUTION: Left and right yokes 12, 15 are provided with short rings 30, 31 wound up with the conductive member of copper or the like for example. By this method, noise is remarkably attenuated, and against a limit for a gear performing no error action, the allowable positional range of a speed detector coil 26 is widened. Accordingly, a mechanism can be formed to need no fine adjustment of the position of the speed detector coil 26.
