A four-pole, three-phase inductionmotor is energized from a 60-Hz supply. It is running at a load condition for which the slip is 0.03. Determine:
(a) The rotor speed in r/min.
(b) The rotor current frequency in Hz.
(c) The speed of the rotor rotatingmagnetic field with respect to the stator frame in r/min.
(d) The speed of the rotor rotatingmagnetic field with respect to the stator rotating magnetic field in r/min.
The expression given in Problem for (S 0 /N 0 )PCM is plotted for a sinusoidal message in Figure to show the performance curves for a PCM system using a polar waveform. (a) Comm
Q. emf produced by windings? The time variation of emf for a single conductor corresponds to the spatial variation of air-gap flux density. By suitable winding design, the harm
The mechanical power produced at the armature of a motor is: P = T a . (power is in watts if torque is N.m and in rad/sec). Some of this will be lost due to friction and
