NOVELTY - The machine has a non-magnetic magnet holder (18) for retaining a set of magnets (16). A stator (12) is arranged radially outward from the magnets for generating a magnetic field. Another stator (14) is arranged radially from the magnets for generating another magnetic field. Each stator has a set of stator poles that are separated by slots, and a concentrated winding i.e. non-overlapping winding, with a respective number of turns formed around each respective stator pole. The magnet holder and the magnets are rotatable between the two stators.    USE - Electric machine e.g. dual stator electric machine and three-phase electric machine, for use in a semi-active or active suspension systems, electric power steering system, electromechanical braking system, hybrid propulsion system, fuel cell propulsion system or electrical propulsion system (all claimed) of a vehicle.    ADVANTAGE - The employment of concentrated windings of the stators increases the active length of the stator within a package size by reducing the end turn length, thus increasing the torque density and the fill factor of the winding, and hence providing high power density with fast response times. The concentrated winding reduces an overhang of each respective winding with respect to each stator pole of each stator for improving machine efficiency without affecting the thermal performance of the machine. The concentrated windings allow utilizing an increased number of magnets i.e. rotor poles in the electrical machine, thus reducing the thickness of the stator core and avoiding the need for a rotor core and shaft, and hence reducing the overall weight of the electrical machine. The increase in the number of magnets generates sinusoidal back electromagnetic force that provides an advantage of reducing torque ripple. The stator poles are separated by slots, thus optimizing the torque output of the electric machine. The concentrated windings are configured so that the majority of the overall winding is formed as a part of the turns as opposed to exit wires coupling the respective turns, thus concentrating the length of the entire winding to each stator pole, thus reducing the stator copper loss and improving the efficiency of the electrical machine.
