You have this backwards. BEMF is what makes electric motors efficient. Were it not for BEMF, they would be a dead short and consume vast amounts of power. It's the BEMF which keeps the losses to a small percentage of the work done. If you want OU, then you need to *increase* not decrease the BEMF. BEMF of a motor is also the forward EMF of a generator, which makes it obvious that for a motor to produce more power than it consumes, the generator EMF must exceed the input power, IOW the BEMF must exceed the applied voltage.
