Question

gear box has ratio 8:1 to the .9-m diameter wheels. ARMATURE HAS SOURCE WHERE THE VOLTAGE CAN BE VARIED FROM 0 TO600--IGNORE ALL LOSSES. A) DETERMINED REQUIRED VALUE OF k to give a speedof 12.5 m/s at an armature V of 600Volts. b) with k from (a) whats the armaturecurrent to provide athrust of 8 kN? c) the speed range above 12.5 m/s is provided by fieldweakening with constant arm voltage of 600V. whats the requiredvalue of k at a speed of 25 m/s?
