I am pondering the overspinning of this motor by the factor of 1.66 relative to the factory data to gain some efficiency. 1.66 times the rpm means 2.6 times less heat generated in the windings at a given output. Now of course higher rpm means more eddy current losses also more heat in the bearings, but the gain seems to outweigh the losses so this way the motor will produce far less heat overall. Sure the rotor will be hotter but nowhere near as much hotter as the windings will be cooler. Is there any fault with my thinking? Some expert advice is appreciated. Thanks
