Electric motors: state of flux?
Motor innovations are an overlooked enabler for the electrification of transport. This 15-page note explores whether axial flux motors could come to dominate in the future. They promise 2-3x higher…
Axial flux motors: leading companies and products?
…higher than a typical AC induction motor in heavy industry. Other technical parameters of these motors are also compiled. Leading companies are also profiled later in the data-file, based on…
Electric motors: variable star?
Variable frequency drives precisely control motors. Amazingly they could reduce global electricity demand by c10%. We expect a sharp acceleration due to sustained energy shortages, increasingly renewable-heavy grids and excellent…
Electric vehicles: motors and magnets?
…permanent magnet motor for the rear wheels, and induction machines on the front wheels. The induction motors are often idled for efficiency reasons, and only used when extra front-wheel power…
Power grids: opportunities in the energy transition?
…opportunity. There are 50bn electric motors in the world, consuming half of all global electricity. But most motors are inefficient, rotating at fixed speeds determined by the frequency of the…
LNG liquefaction technologies: an overview?
…Snohvit LNG started up in 2007, with the first e-drive system in the world, and what were at the time, the world’s largest high-voltage and high-speed synchronous motors, with 180MW…
Vehicles: fuel economy and energy efficiency?
…smaller vehicles such as bicycles, scooters, motor-cycles and simply ‘walking’. $299.00 – Purchase Checkout Added to cart Our numbers are built up for each category, in kWh-per-mile, miles-per-gallon, energy efficiency percentages and…
Energy economics: an overview?
…the data-file, across our models of Air Separation, Cables, Comminution, Compressors, Electric Motors, Electrowinning, Fans, Flotation, Gas Dehydration, Harmonic Filters, Heat Exchangers, Inverters, Motor Drivers, Pumps, Rankine Engines, Tanks and…
Variable frequency drives: the economics?
This data-file aims to capture the economics of variable frequency drives, which precisely adjust the operating speeds of electric motors. We reviewed 10 case studies and found an average energy…
Established technologies: hiding in plain sight?
…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…
