Samarium is written in C++ using the Microsoft Visual Studio C++ software package. It extensively uses OpenGL that is supplied with all Windows operating systems after Windows 2000. Samarium allows graphical 2-dimensional and 3-dimensional visualization of the electromagnetic parts of the motor. Several OpenGL functions and tools are supported to better visualize a new motor design. The results of the computations are displayed in a manner that allows easy identification of the important parameters to the design. Graphical outputs of several motor parameters is also supported. Samarium is a tool that allows the electromagnetic modeling and design of motors, the mechanical design is not addressed or considered. |

The design capabilities include advanced analytical design by traditional and modified methods of motor design, finite-element analysis for the electromagnetic modeling of motor parameter with up to third order constrained Delaunay triangular meshes. Visualization and analysis of all output data is fully supported with the aid of several engines. Slotless motor design in Samarium has several limitations, so please check with us if your primary task involves slotless motors.
Bifurcations
Samarium can design slotted motors with bifurcated teeth. Four types of bifurcations are supported.
1) Bifurcations that are exactly the same as the slot openings, with 75% height of the tooth tip thickness
2) Semi-circular
3) Rectangular
4) Triangular
The depth of the bifurcations are not taken into account in the analytical design calculations. The only impact is on the Carter's coefficient and all related variables. Cogging torque calculations are performed with the bifurcations. Please use the FEA engine for more detailed analysis.
