Two series motors are exactly alike in construction except that the air gap of one is slightly greater than that of the other. When taking 70 A at 600 V, one motor runs at 800 rpm and the other at 850 rpm. If the two motors are mechanically coupled and connected in series across 600 V, at what speed will they run when the current is 70 A? Total resistance of each motor is 0.28 ohm.
