This is mainly due to the fact we are gearing these motors for desired temps after a certain runtime, not for all out power. So they are not producing the max power, and taller gearing will load them more, pulling out that power, at the expense of heat production. If the motor is 85% efficient it will have to get rid of 15% of the total power it draws as heat. So 15% of 1000 watts is 150, while 15% of 2000 watts is 300... If we had better methods of cooling (such as water cooling or forced air) we could run these motors much more aggressively, and closer to their potential.
