WebMar 15, 2024 · DMAIC is a data-driven problem-solving technique designed to identify and address inefficiencies in a process, which improves its outcomes and makes these improvements more predictable. The acronym stands for the five phases — Define, Measure, Analyze, Improve, and Control, and it is pronounced “duh-may-ik.”. WebPhase control relays: operating principle, types, marking + how to adjust and connect. The result of the technical situation, when the stator windings of the motor consume more current than the set parametric values, is excess heat. This factor causes a decrease in the quality of motor insulation. Equipment fails.
