NASA and General Electric are negotiating a new partnership agreement to start scaled model tests of open-rotor counter-rotating fan systems later this year for a next-generation jet engine design for ...
Counter-rotating wind turbines (CRWTs) represent an innovative paradigm in wind energy conversion, employing a dual rotor mechanism in which two coaxial rotors spin in opposite directions. This ...
Midea Group has patented a counter-rotating motor for high-speed blenders. The motor includes a stator with outer and inner windings, an inverter for synchronous excitation, an inner rotor rotating in ...
