Q22. Class A chopper is supplying a DC motor with FWD, motor inductance= 6 H & resistance- 12 SN, input voltage=220 V, chopper frequency = 1kHz and ON time (ton) = 0.5 ms, The back emf of the motor is 5 V. Using this data, select the correct answer for the following aks questions. a. The maximum value of the load current equals to O 8.75 A O 10 A O 9.17 A O None of the preceding b. The minimum value of the load current equals to O 8.745 A O 9 A O 9.16 A None of the preceding c. The average load current equals to | 8.75 A O 9 A O 9.16 A None of the preceding.

Ashunt-wound DC motor with the field coils and rotor connected in parallel (Figure 1) operates from a 130 V DC power line. The resistance of the field windings, R, is 208n. The resistance of the rotor, R, is 4.90 2. When the motor is running, the rotor develops an emf E. The motor draws a current of 4.46 A from the line. Friction losses amount to 45.0 W Part C Compute the emf E. > View Available Hint(s) undo redo Tese keyboard shortcuts Help Submit Part D Compute the rate of development of thermal energy in the field windings.
