…Electric motors. Almost 50% of all global electricity is consumed by 50bn AC induction motors. But most are over-sized. Their power consumption is determined by their nameplate capacity and the…
…electric motors c35% more efficiently, which matters for electrifying compressors, for heat pumps, and as motors absorb 15% of all useful global energy. Semis are also crucial for battery charging…
…below. The largest categories are electric motors (15%), passenger cars (13%), residential heat (10%), manufacturing processes (6%) and other electrical appliances (5%). Although note that this is also because these…
…the early 1980s. (2) How are neodymium magnets used? These magnets are used in electric motors, generators (especially wind turbines) and other electronics (especially computer hard drives, audio equipment, and…
…magnetic forces on pages 2-3, covering magnetic fields (m3), magnetic flux (Webers) and magnetic flux density (Teslas). Magnets are the basis for all electric motors and over 95% of today’s…
…Volvo abandoned a target to sell only electric cars by 2030. https://thundersaidenergy.com/2024/09/05/electric-vehicles-saturation-point/ Our take is that electric motors are superior to ICE engines in power, performance and vehicle emissions; but…
