Question

Problem 7: VT = 100 V is applied to a shunt connected DC motor with Radj = 50 ? and the magnetization curve shown. For the motor, RA = 0.5 ? and RF = 20 ?. The motor has negligible rotational losses. What is the maximum speed and maximum torque available from the motor? (10 points) EA = (30 V/A) * IF nm = 1200 rpm

Step 1

The field current \( I_F \) is given by: \[ I_F = \frac{V_T}{R_F + R_{adj}} \] Given: \[ V_T = 100 \, \text{V} \] \[ R_F = 20 \, \Omega \] \[ R_{adj} = 50 \, \Omega \] \[ I_F = \frac{100 \, \text{V}}{20 \, \Omega + 50 \, \Omega} = \frac{100 \, \text{V}}{70 \, Show more…
