How to drive a 32 hp ac generator by a 5 hp ac motor?
Why do you want to do this? Are you attempting to get 32 HP of output from the generator using the 5 HP motor? Won't happen. The most you can get out of this arrangement is 5 HP minus the heat lost by the motor and generator and whatever losses there are in the mechanical connection between the motor and generator. And if you put 32 HP of electrical load on the generator while supplying it with 5 HP of mechanical energy from the motor, you will just stall the motor, it will not be able to overcome the torque from the generator.
