Abstract: Firstly, this paper put forward an analytical calculation method for the axial electromagnetic force caused by skewed slot, and the calculation formula was derived. On theory analysis basis, a method for calculating the axial electromagnetic force caused by the misalignment of stator and rotor based on twodimensional static electromagnetic field simulation was proposed, the simulation steps of singlesegment and multisegment core motor were introduced in detail. The experimental results show that the proposed calculation method is correct in theory, high in calculation accuracy, and can greatly reduce the calculation amount.
