A 35.2 HP, 250 V, 100 A, 1500 RPM, series DC motor with no armature reaction is considered in this problem. This motor has a series-field winding of 10 turns per pole. Its armature resistance in RA-0.05 , and its series field resistance is Rs=0.05 2. %3D The magnetization curve at 1500 RPM is given by the following table: EA (V) 50 200 (Amp.turns) 125 755 95 180 1280 150 200 1500 212 2000 243 3000 229 250 253 4000 500 1000 2500 3500 The motor is operating at rated voltage, armature current of 100Amperes, and with rotational losses of 1500 Watt. Find the speed of the motor. Select one: O a. None Ob. Speed =D1500 RPM OC. Speed n= 938 RPM O d. Speed n= 2400 RPM
