Fixed-angle rotors are suitable for applications that require high resolution and fast sedimentation, such as pelleting of cells, organelles, viruses, or proteins.

A novel fixed twin-rotor unmanned aerial vehicle (UAV) based on the variable angle louver rudder (VALR) is developed in this work. In view of the mechanical characteristics under the action of the ...

This work introduces a phasor diagram based method to determine load conditions for which the round rotor synchronous machine armature current is on the quadrature axis. This load condition is ...
