A Condensed Introduction to the Doubly Fed Induction ...

The increase in wind power penetration, at 456 GW as of June 2016, has resulted in more stringent grid codes which specify that the wind energy conversion systems (WECS) must remain connected to the system during and after a grid fault and, furthermore, must offer grid support by providing reactive currents. The doubly fed induction generator (DFIG) WECS is a well-proven technology, having ...

Electric motors :: Ori Codes

Electric motors The main question concerning electric motors is: brushed or brushless? Brushed pros: cheaper, simpler, better for off-road. Brushed cons: heavier, bigger, worse power efficiency (75-80%), they wear out in time. Brushless pros: long lifespan, much better speed and handling, better power efficiency (85-90%). Brushless cons: much more expensive, worse for off-road.

Upper Limb Exoskeleton Systems—Overview

2020-1-1 · Fig. 1.1 provides a chronological overview of the development of around 40 exoskeleton systems. Some well-known end-effector devices are also covered. The horizontal axis ranges from 1980 to 2020, while the vertical axis generally categorizes the upper limb exoskeleton systems in their control methods: position/velocity control, impedance control, admittance control, and force/torque control.
