Rotor Of A Claw Pole Electric Machine
Abstract: CLAW POLE SLOT IN A ROTOR OF AN ELECTRIC MACHINE Claw pole slot in a rotor of an electric machine is disclosed herein.The present invention discloses the design of claw pole rotor of an electrical machine to minimize the flux leakage. The rotor has a field coil wound around an iron core. It has a pair of claw poles mounted onto a shaft. Each of the claw pole has plurality of claw fingers projecting outwards, and are oppositely polarized and are arranged circumferentially. Permanent magnet is inserted onto the fingers of the claw which alternate between north and south polarities upon energization. A linear slot cut (2) is formed near the inner diameter of the claw pole finger (1) as depicted in FIG. 2, which minimizes the flux leakage in the rotor thereby improving the efficiency and power density of the electrical machine.
