Abstract: A system (100), electromagnetic actuator (102) and track (101) for braking are provided. The actuator (102) includes pole portions (109) extending from back-iron portions. Respective longitudinal axes (104) of the pole portions (109) are arranged about parallel to one another and about perpendicular to a common movement axis (104). A pole pitch of the pole portions (109) is selected to induce eddy currents in a segmented track (101), such that the eddy currents are present in a skin depth at more than one surface of segments (105) of the segmented track (101) when the pole portions (109) are moving at given speeds. Eddy current generated losses occupy about an entirety of a volume of a segment (105) of the track (101) below a given intermediate speed, and the eddy current generated losses occupy at least one third of the volume of the segment (105) at a given maximum speed greater than the given intermediate speed. Individually controllable electrical windings are around respective pole portions (109).

Abstract: A vehicle with offset propulsion motors is provided. The vehicle comprises: a body; and a plurality of propulsion motors at a side of the body, arranged in a line about parallel to a movement axis of the body. Displacements between adjacent propulsion motors along the movement axis are selected according to an electrical period of poles of the plurality of propulsion motors, and an offset distance. The offset distance is determined by dividing the electrical period into the offset distance to determine a remainder. The electrical period divided by the remainder is about equal to a number of the plurality of propulsion motors divided by a given integer value that is less than the number of the plurality of propulsion motors, and produces a largest common divider between the given integer value and the number of the plurality of propulsion motors of “1”.
