TF Linear Motor with Passive Guideway for Low Speed Transport

Linear motors are frequently proposed for the propulsion of low speed transport systems such as short-haul passenger transport in public areas or in urban light transit systems. In this paper an innovative configuration of a modular transverse flux permanent magnet (PM) motor with variable reluctance secondary is presented, with both windings and PMs placed on the mover. The thrust performance are evaluated by analyzing a simplified 2D model and compared with the ones related to a surface mounted PM motor, the same active width and length of the mover being maintained. In particular, the influence of the tooth profile on the thrust average value and ripple is taken into consideration to optimize the motor configuration.
