Abstract

PURPOSE: To simply maintain a carrier portion in space while improving performance, while smoothly moving the carrier by filling non-magnetic materials with lubricating properties onto surfaces where the stator and yokes face opposedly each other.
CONSTITUTION: A magnetic stator 5 fixed around a shaft 4 and a plurality of yokes 1a∼1c each provided with exciting coils 2a∼2c in the longitudinal direction around the stator 5 are disposed. Non-magnetic materials 6 with lubricating properties are filled among a plurality of the yokes 1a∼1c and the stator 5 and at least one side of a plurality of the yoke 1a∼1c sides and the stator 5 side. Consequently, magnetic space is retained among a plurality of the yokes 1a∼1c and the stator 5, and a plurality of the yokes 1a∼1c can be shifted in slide shapes in the longitudinal direction of the stator 5. Thus, the structure is simplified while its performance can be improved.
