DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a linear hybrid motor having both a linear pulse motor and a linear induction motor, and a method of using the same.

In general, Rini? Since the control force for the induction motor is large (starting + 1f), it is used for high adjustment of 111 degrees (111 degrees), but with the motor for fixed point stopping and 12 (1, 1 is unsuitable). - 10,000, for a linear pulse - ta is constant 8j, sum (ζ′1
1 is easy and self-holds the stop position lj! It has a lot of power, but its movement speed is slow. This J, a linear induction motor and a linear pulse motor (:1) have different advantages and disadvantages. In the low speed range, one pulse is changed to one pulse,
Concepts for near-high solid motors that take advantage of the strengths of both motors are already known, but many of these are mechanical combinations of the two motors, and there are also There is a drawback that the shared culm U) (1, (< , so C1[-ta becomes a doll).

This invention is intended to improve the following drawbacks:
1, so the primary side and the secondary side are shared, and by switching the excitation 21 coil, change to C, linear induction Tanabata Karari 2i' pulse Tanabata \, or vice versa. The purpose is to provide a compact linear hybrid motor with high utilization of the stator, excitation, and coil.
