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”.
