1. A design assist apparatus provided with a processor configured to execute a process of assisting design of a mechanical device driven by a feedback controlled electric motor,
wherein the processor is configured to:
set a plurality of parameters of a mathematical model of a mechanical component forming the mechanical device that are adjustable,
compute a pole of a transfer function of the mechanical device associated with one or more vibration modes of the mechanical device according to the parameters, and
create and display a stability determination diagram including an isoline of a real part of the pole of the transfer function with respect to the parameters, the isoline defining a stable region where a value of the real part is negative and an unstable region where a value of the real part is positive, the stability determination diagram including one or more symbols respectively corresponding to one or more candidates for the mechanical component, each symbol indicating parameters of a corresponding candidate.
