Question

A linear motor has the following specifications: B = 0.8T, l = 2m, R = 0.3 ohms, Vb = 300V. When the bar moves to the right, there is a drag force KdV, where Kd = 6(N/m/sec), and v is in (m/sec)! Determine (a) the “starting” current (A), and (b) force (N). What is the “steady state” (c) velocity (m/sec), and (d) current (A), when the applied voltage is 300V.
