In the paper comparative studies of 2D-3D disc-type Switched Reluctance Motor (SRM) structures are performed. The calculation of magnetic field distributions and the static torque characteristics have been computed by means of Finite Element Method (FEM) for 2D and 3D motor structures. It has been emphasized that the calculations of the model structure (thanks to axial symmetry) have been done for a half of the volume while the boundary conditions are predefined. 3D structure of the model motor is built up, then the mesh is generated for number of elements exceeding 100 000. The results of 3D calculations are presented in the form of the static torque characteristics and magnetic flux curves versus rotor angular positions and current densities in the stator winding as well. Disc-type SR motors thanks to their specific structures are commonly used in automotive system, servo-drives, etc. The motor structure consists of the stator core toroidally shaped in which slots are placed on both sides of the active surface; moreover stator windings are wounded as Gramma type (made of identical coils surrounding the stator core). SRM are proposed to be mounted at the wheel of gearless electric vehicles (small cars, wheelchair, scooters, etc.).
