Constant speed drive diagram
WebThis article describes the electric drive block diagram, types, and applications. B.S. Iakobi in 1838 developed the first electric drive for propelling a boat by use of a DC battery in a DC motor. The speed of an induction motor can be precisely controlled by varying the voltage and frequency simultaneously. The drive used to control the speed ... WebT n = 3 × 746 188.5 = 11.87 N m. Therefore, the constant k should be. k = T n ω 2 = 11.87 188.5 2 = 3.34 × 10 − 4. Add an Interpreted MATLAB Function block from the Simulink > User-Defined Functions library. Double-click the function block, and enter the expression for torque as a function of speed: 3.34e-4*u^2.
