In this article, the calculation of momentary electromagnetic torque in a brushless shaft permanent magnet motor has been done using Lorentz force theory. In this method, the anti-motor voltage and phase current are used and a new method for calculating the different harmonics of the anti-motor voltage has been presented using an analytical method. The results of the presented analytical method have been evaluated using the finite element software and there is a good match between the presented analytical method and the finite element method. The calculation time in the presented analytical method is much less than the calculation time of Alman software. Finally, by using the analytical method, some geometrical parameters of the motor have been optimized with the aim of reducing the ripple torque.
