(English)(Chapman) || End Chapter Problem 1.21
In this video we solve end chapter problem 1.21 from the book Electric Machinery Fundamentals by Chapman
Q 1.21: The linear machine show n in Figure P1 -15 has a magnetic flu x density of 0.5 T directed into the page, a resistance of 0.25 n, a bar length I = 1. 0 m , and a battery voltage of 100 V.
(a) What is the initial force on the bar at starting? What is the initial current flow?
(b) What is the no-load steady-state speed of the bar ?
(c) If the bar is loaded with a force of 25 N opposite to the direction of motion,
what is the new steady-state speed? What is the efficiency of the machine under
these circumstances?
