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

Many mechatronic systems involve complex motions resulting in highly dynamic motor loads. Motor characteristics, such as rotor inertia, affect this motor load, which makes the design and selection of the complete drive system-consisting of motor, mechanical reducer, and converter-a huge combinatorial problem. The new approach presented in this paper separates the problem into a feasibility and optimization phase, and normalizes it crith respect to the rotor inertia. This yields a fast and automated design procedure for servo drive systems, giving more insight through a set of conveniently arranged graphs.
