A 200 V DC series motor, when operating from rated voltage while driving a certain load, draws 10 A current and runs at 1000 r.p.m. [cite: 109] The total series resistance is 1 $\Omega$. [cite: 110] The magnetic circuit is assumed to be linear. [cite: 111] At the same supply voltage, the load torque is increased by 44%. The speed of the motor in r.p.m. [cite: 111, 112] (rounded to the nearest integer) is ________ .
