SRM Design OptimizationMotors & Generators with MagNet
The design of Switched Reluctance Motors (SRM) is a complex optimization problem involving a large number of geometrical and electrical parameters. In practice, this can be a challenging task involving a large number of iterations and a long design cycle.
The example presented here demonstrates how OptiNet searches for the improved design of a 8/6 SRM to maximize the torque generated while conforming to manufacturing and operating constraints.
METHODS and RESULTS
SETTING the VARIABLES in OptiNet
OBJECTIVE FUNCTION - MAXIMIZING the AVERAGE TORQUE
CONSTRAINTS - AVERAGE TORQUE
MAXIMUM TORQUE ON ROTOR vs SOLUTION INDEX
After 13 hours, OptiNet has evaluated the design objectives and constraints against over one hundred thirty different SRM designs (as defined by the tolerances on each variable), represented here by each point on the solution index.
