This paper considers the study of methods for reduction of the cogging torque in permanent magnet machines. Cogging torque has been analyzed to be reduced by slot skewing, width of slot opening, magnet pole radius and also by mounting of the magnets. Electromagnetic simulations of the PM generator were performed by using finite element analysis. Virtual torque method has been used for calculation of the cogging torque.
