Synchronous linear motor operating method for use in vehicle, involves determining current directly or indirectly by coil, and determining induced voltage from measured values for current and voltage using parameters indicated by machine

摘要

The method involves providing a primary part (1) with a primary coil (4) and a secondary part (2) with permanent magnets (3). The magnets are moved relative to the primary part, and current is determined directly or indirectly by the coil, and voltage induced in the coil is determined directly or indirectly. The induced voltage is determined from measured values for current and voltage using parameters indicated by a machine. Independent claims are also included for the following: (1) a synchronous linear motor comprising a coil (2) a system for operating a synchronous linear motor, comprising a synchronous linear motor propelled vehicle.
