Two identical 3-phase, 500-V induction machines are mechanically coupled for a back-to-back test. One machine is motoring from a 500-V, 50-Hz supply and the other is generating on to a 3-phase, 500-V synchronous machine for which the fre- quency can be controlled. It is required to run the motoring induction mạchine at 40 hp. Neglecting the slight change in the generating machine parameters due to oper- ating at a reduced frequency, estimate the rating of the synchronous machine for this duty and the frequency at which it must be run.
