Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

Pitch-controlled variable-speed horizontal-axis wind turbines (HAWTs) are increasingly being investigated for use in electrical power production. The governing equations of HAWTs are expensive to ...

The fatigue response of 7075-T73 aluminum alloy (cyclically hardening) and SAE 1045 (mod.) steel (cyclically softening) was investigated in air and corrosive environments under constant amplitude and ...
