    摘要: A linear motor elevation system comprising an elongated magnetic induction member (21) mounted along the hoistway. The induction member (21) has a plurality of magnetic poles (21a) disposed at equal intervals along the hoistway so that they face toward the armature (27). An elevator car (4) or a counter weight has attached thereto a field magnet (26) disposed in a facing relationship with respect to the magnetic induction member (21) for generating magnetic poles in the induction member (21). The field magnet (26) comprises an iron core (23) having a U-shaped cross section including a central web portion on which a field winding 24 is wound and parallel flange portions extending from the web portion toward the magnetic induction member (21). An armature (27) comprising armature windings (25) wound on teeth formed in the magnetic induction member (21) is also disposed on the car (4) in a facing relationship with resepct to the magnetic induction member (21) for generating a progressive magnetic field acting on the magnetic induction member (21) to generate an electromagnetic drive force for moving the car (4) along the hoistway. The magnetic induction element (31) may have a guide surface which is in guiding engagement with guide rollers (41) mounted on the car (4) for guiding it along the hoistway.
