An analytical technique for the calculation of torque produced by a transverse flux machine is developed in this study. In this technique, the magnets are replaced by their equivalent current sheets and the torque is calculated using the Lorentz force equation. The flux density distribution is calculated using a conformal mapping method that takes into account curvature and slotting. The result is a relatively simple equation that relates torque to the electric and magnetic loadings of the machine and a flux factor that depends on key machine geometrical parameters. The results of the analytical model are verified using finite‐element analysis and experimental data.
