    摘要： A position detection system includes a linear motor having a rod in which magnetic poles of N pole and S pole are arranged alternately in an axial direction and a plurality of coils surrounding the rod a magnetic sensor for detecting change in the direction of the magnetic field of the rod caused by linear movement of the rod relative to the coils to output a sine wave signal and a cosine wave signal which are 90° phase shifted with respect to one another, and a position detecting circuit for detecting a position of the rod relative to the coils. As the magnetic sensor detects the change in the direction of the magnetic field of the rod, the sine wave signal and the cosine wave signal output from the magnetic sensor hardly vary even when the distance between the rod and the magnetic sensor is changed.

The drive guide apparatus has a linear motor and a guide mechanism that has a rail and a moving member provided to be movable relative to the rail. A primary side of the linear motor is connected to the rail. Thermal insulators for blocking heat generated from the primary side of the linear motor are provided between the primary side and the rail of the guide mechanism to which the primary side is connected directly or indirectly.

The linear motor includes a magnet rod composed of a large number of magnetic poles arranged with predetermined pitches along an axial direction and a forcer having a through-hole into which the magnet rod is loosely inserted and reciprocatable relatively to the magnet rod according to an applied electric signal. The forcer is composed of a forcer housing in which the through-hole is defined and a coil member which is arranged on an inner peripheral surface of the through-hole of the forcer housing and to which the electric signal is applied. The forcer housing is formed by mold forming with an insulating nonmetal inorganic material.
