This work proposes a new linear motor for an electric bus propulsion system. The vehicle is powered by a new topology of permanent magnet synchronous linear motor. The slider of the motor is integrally attached to the floor of the vehicle to propel. The motor is fed with an alternating voltage conveniently applied to a three-phased stator coils which are distributed in the rails that attach the vehicle travel. Therefore, the motor requires no energy storage system. A set of permanent magnets located on the slider and disposed in Hal Bach array, maximize thrust force. The new slider topology is able to reduce the thrust ripple, while maintaining its average value. At the same time it reduces the normal force, which in this type of motor with ferromagnetic slotted stator, is an attraction force. The study of the dynamic behavior of electromagnetic forces concerning the movement of the slider on the stator is shown as well as the motor structural design. A 3D Finite Element simulation tool is used.
