Techno-economic optimal power rating of induction motors

Impact Analysis From Driving Patterns and Environmental Conditions on the Operational Range of Electric Vehicles

“…4. The main reason why the operational range decreases at lower speeds is due to the fact that the electric motor efficiency decreases at low speeds [19]. It was found that the range is the highest when the driver holds a cruise speed of approximately 50 km/h.…”

Energy efficiency measures in electric motors systems: A novel classification highlighting specific implications in their adoption

“…Among others, motor operating conditions and the life cycle costs represent crucial elements to the decision: usually, premiumefficiency motors look economically efficient when replacing motors operating over 2,000 hours per year [65] and it can even be worthwhile replacing fully serviceable standard efficiency with high efficiency ones [84]. But, research has recently discussed that the decision of selecting the techno-economic optimal power rating (in terms of motor operating conditions) should be carefully based on minimizing energy consumption throughout motor service life, so to minimize its life cycle costs [86].…”

Fatigue aging of insulation of traction motors of diesel locomotives

“…The problem of increasing the reliability of transport electric machines, and in particular the study of fatigue strength processes of electrical materials (namely, insulation), is also given much attention in various research works. [1][2][3][4][5][6][7][8][9][10][11]. Such a concept as fatigue failure of insulation material refers to a type of mechanical failure.…”
