An electrical machine includes as part of its stator XRAM windings for multiplying current output of the machine. The XRAM windings are coupled to switching elements that are configured to produce current multiplication for output to an external load. The XRAM windings may be in slots in the stator, or may be elsewhere in the stator, operatively coupled to other windings in the stator. The stator may be operatively coupled to a rotor and hence to an inertial energy source, such as a flywheel on the same shaft as the elements of the electrical machine. Short circuiting of select windings of the machine can advantageously cause a shifting and concentration of a machine airgap flux of the machine over other windings, and increasing their magnetic storage energy.
