An efficient procedure for checking performance limits in servo drive selection and optimization

Many mechatronic systems involve complex motions resulting in highly dynami c motor loads. Motor characteristics, such as rotor inertia, affect this mo tor load, which makes the design and selection of the complete drive system -consisting of motor, mechanical reducer, and converter-a huge combinatoria l problem. The new approach presented in this paper separates the problem i nto a feasibility and optimization phase, and normalizes it crith respect t o the rotor inertia. This yields a fast and automated design procedure for servo drive systems, giving more insight through a set of conveniently arra nged graphs.
