Doubly-fed variable speed pumped-storage unit (VSPS) has been proposed as an alternative to the traditional synchronous speed pumped-storage unit (SSPS) due to its advantages of wide operation range ...

Eaton today announced it has been chosen to supply electromechanical variable valve actuation technology to Great Wall Motor. ... This also enables a safe rocker switch at high engine speed.

In this article, a robust cascaded deadbeat predictive speed control method (PSC) is proposed with speed and disturbance observer for the dual three-phase variable-flux permanent-magnet synchronous ...

Variable speed motors and dimmers, like those in high-tech HVAC systems or LED dimmer switches, draw power in a way that's less predictable than older appliances. This makes them harder for Sense to ...
