Brownian motors behave completely different than macroscopic Carnot engines because they are kept away from equilibrium by external fluctuations or temperature gradients. Although the studies on the Thermodynamics of these motors have been mainly focused on efficiency, high efficiency may be achieved with considerable heat dissipation losses. In this work the heat dissipation from the motor to two thermal baths is numerically obtained. The process of heat transport is related to the effective temperature through the generalization of the fluctuation-dissipation theorem for systems far from equilibrium.
