This invention relates to an electrical machine that functions both as an electrical motor as well as a generator concurrently. This motor or generator consist of three major members i.e. an outer stationary member called the stator (10) and two inner rotating member called Rotor A (20) and Rotor B also known as the armature (30), both of which is mounted within each other on the same rotating axis. Rotor A (20) is mounted inside the stator (10) and is made of plurality of permanent magnets arranged in such a way that there are a plurality of alternating poles is available on both the outer and inner surface. It is the plurality of alternating poles on the outer surface that is used to interact with the magnetic field from the stator windings. The inner alternating poles is used to interact with the alternating magnetic field from the coil windings on Rotor B (30) or the armature (30). Both Rotor A and Rotor B are mounted on the same rotating axis and are controlled by one way bearings or cam clutch so that they can only rotate in one direction. By reversing the polarity of the DC current flowing through the armature, will cause a push and pull effect interacting on both Rotor A and Rotor B. Controlling the timing of the alternating DC current will cause both Rotor A and Rotor B to move only in one direction either clockwise or anticlockwise with the aid of one-way bearings (80) mounted on both Rotor A and Rotor B. This timing is achieved with feedback signals from an emitter disc mounted on the rotors and an electronic control circuit to alternately switch the current applied to the armature coil windings (15)
