That gives a misleading answer because you are equating the torque at different speeds for 1 CIM vs 2:


1 CIM at 45 amps = 111.5 ozin @ 3586 rpm = 295.6 watts

2 CIMs at 45 amps total (22.5 amps each) = 104.4 ozin @ 4503 rpm = 347.6 watts

or

2 CIMs at 47.6 amps total (23.8 each) = 111.2 ozin @ 4450 rpm = 366 watts

1 CIM at 47.6 amps = 118.3 ozin @ 3480 rpm = 304.5 watts
