摘要: Effect of external periodic regulations on a symmetric Brownian motor performing between two temperature sources was investigated. By means numerical calculations, we found that: (i) The can control magnitude and direction the motor’s current to large degree. As one compartments is regulated, be both inversed maximized, dependent amplitude frequency driving force. If forces with identical amplitudes frequencies are employed regulate respectively motor, current’s will make oscillations phase difference them. In addition, regulation also change thermal rectifier system as switch. (ii) Optimal regulating parameters enhance pronouncedly conversion efficiency energy motor.
