This paper represents a analytical, simulation and experimental study of power factor in mechanical system. In electrical system, power factor is often used to evaluate how intense we can use the electrical power as a active electrical power. It is useful when considering the power consumption of the electrical system. However, this kind of approach did not exist in mechanical system. In mechanical system, we consider mechanical loss of energy, however we did not consider the amount of power used in the phase change. Thus this study introduces the power factor in the mechanical system and investigates how much power is actually used in the motion. Power factor of certain frequency of the motion was analyzed and compared with the simulation results. Experiments were conducted to further study the behavior of power factor in many situations. Experimental results signify power factor changes due to the speed of the motion and also path of the motion.
