question
Two 60-cycle motors are connected in concatenation to drive a load. If machine 1 has six poles and machine has eight poles, (a) calculate the speed of the combination if the slip is 0.075. (b) At what other speeds can the load be driven if each motor is operated separately, assuming the same value of slip ?
