Problems 8-1 to 8-12 refer to the following dc motor:
Rotational losses = 3550 W at full load
Magnetization curve as shown in Figure P8-1
If the motor is connected cumulatively compounded with R = 175 W: adj
(a) What is the no-load speed of the motor?
(b) What is the full-load speed of the motor?
(c) What is its speed regulation?
(d) Calculate and plot the torque-speed characteristic for this motor. (Neglect armature effects in this problem.)
