What will be an ideal response?
A dc, separately excited motor is used in a forklift. The motor is driven by a full- wave, ac/dc converter. The voltage on the ac side is 120 V (rms). The field constant of the motor K? = 3 Vs. The armature current is continuous under the loading conditions. At a load torque of 300 Nm and triggering angle of 40o , the motor speed is 100 rpm.
a. Calculate the triggering angle required to block (stop) the motor. b. Calculate the average voltage across the motor terminals if the triggering angle increases to 120°. c. Calculate the new speed of the motor at the condition described in part (b). d. Sketch the speed-torque characteristics and show all the operating conditions.
