The high-speed linear motor disclosed herein comprises a stationary part and a moving part. The stationary part is composed of conjoined upper and lower primary structures. Each primary structure consists of at least two field magnet modules. The moving secondary part then lies between the two primary structures by a non-wearing bearing so that it can move with high efficiency and no friction loss. A position sensor is provided for precisely positioning a work piece and there is no worry about interruption of feed back signal because there is no wire connection at the moving part.
