The invention relates to Permanent magnet machines with asymmetric rotor construction to increase peak air gap flux density in the machine, comprising a rotor assembly having an asymmetric configuration of the rotor core (406) with a first set of permanent magnets (401) disposed to form a V-shaped spaces and separated by a second set of permanent magnets (402) disposed between the V-shaped spaces to form the north pole and the south pole of the rotor, the north pole and the south pole generating different values of peak air gap flux density due to asymmetric design of the rotor; a first plurality of flux equalizers (403) constructed inside the V-shaped spaces to equalize the peak air gap flux density of the north and south pole; and a second plurality of flux barriers (404) formed on the rotor core (406) at the bottom of the first set of permanent magnets (401), which provide a high reluctance to the magnetic field and reduce the leakage of flux through the bottom of the magnets (401).
