In a sinusoidal-waveform, permanent-magnet brushless servo motor, phase-to-phase resistance is 8.0 Ω and the phase-to-phase inductance is 16.0 mH. The voltage constant, which is the ratio of the peak phase voltage induced to the rotational speed, is 25 V/1000 rpm; p = 2 and n = 10,OOO rpm. Calculate the terminal voltage if the load is such that the motor draws 10 A rms per phase. Calculate the power factor of operation
