The first lever part designed to connect with the lock operating lever is associated with a first spring (5) which biases it towards a stop (6) fixed on the lock whilst a second spring (10) producing a smaller torque than the first is set between the two lever parts so that it biases...
where P is the power produced by the wind turbine, ρ is the density of the air, U is the freestream velocity, and A is the cross-sectional area of the wind turbine. This is the same equation used in calculating the efficiency of a HAWT, however the cross-sectional area is calculated...
A Power Module with rated line current Ie is directly connected to a low-voltage transformer and the PCC is the transformer connection terminal. The equation for the ratio between rated line current Ie of the Power Module and rated current IN of the transformer is Ie = 0.25 × IN. The ...

Under static equilibrium conditions, the screw rotates at a constant speed in response to the input torque T shown in the free-body diagram above. In addition, the load force F, normal force N, and sliding friction force Ff act on the power screw. tive m
In this paper, a theoretical estimation model of TBM thrust, torque, and power in the rock–soil interface (RSI) of mixed ground is developed, including a new force model for the drag cutter that accounts for chamber pressure and soil friction. A distrib
The first method consists in converting current commands in the rotor reference frame to a stator reference through a transform equation based on the generator parameters and the instantaneous rotor position. The second method proposes to estimate the rotor position/speed using a fundamental-frequency ...
