Prospective LCA of E‐Methanol Along the Transformation of Steel Industry

Chemie Ingenieur Technik, EarlyView.
The environmental effects of change in steel production route on e‐methanol production are analyzed as they shift from blast furnace route to direct reduction route. Specific hydrogen demand reduces, as do the avoided CO2 emissions. E‐methanol's overall carbon footprint stays in a narrow range of −1 to −1.1 kg‐CO2‐eq./kg‐methanol.

Analysis of Cogging Torque Ripple Based on Multiple Square-Wave Radial Superposition MMF for Wound-Field Synchronous Motors

IEEE Access
Bilateral slotting restricts the application of wound-field excitation synchronous motors in underwater vehicles, which focus on vibrations. There are few studies on the wound rotor, and the theory of permanent magnet motors is not entirely applicable ...

Cogging force investigation of a free piston permanent magnet linear generator

IOP Conference Series: Materials Science and Engineering, 2017
Better performance and higher efficiency of the vehicles can be achieved by using free piston engine, in which the piston is connected directly to the linear generator and waiving of any mechanical means. The free piston engine has the ability to overcome or reduce many of the challenges, such as the carbon dioxide (CO2) emission and fossil fuel ...

Cogging force mitigation techniques in a modular linear permanent magnet motor

IET Electric Power Applications, 2016
Modular linear doubly salient permanent magnet motors are well adapted to linear propulsion systems because of their distinct characteristics, such as high efficiency and power density, reduced maintenance and initial cost, low noise and permanent magnet (PM) leakage flux, and fault tolerance capability.

RBFNN Based Linear Motor Cogging Force Identification for Lithography Machines

IFAC-PapersOnLine, 2015
Abstract The cogging force of linear motors significantly affects the positioning accuracy in ultraprecision lithography machines. Optimal motor design cannot completely eliminate it, leaving the realtime active compensation as the only means to counteract its adverse effect.
