Simulation of Idle Running Operating Characteristics for Low-Power Asynchronous Motors

Abstract
The opportunity of this work is backed by the possibility to predetermine the operating characteristics of an asynchronous motor in idle running. This contributes to the realization of a high performance electric drive. An analysis is aimed for low power asynchronous motors used in different types of applications, such as robots, medical equipment and home appliances, transportation systems a.s.o. It is insisted on an advanced mathematical model that provides the best results in simulations and applications [1]. The simulations are important for their quality and precision because they allow us to anticipate the motor behavior and also to establish the errors between the simulation and experimental results. The mathematical model used considered the equations written in the two-axes theory, the rotor quantities being expressed in the fixed stator reference frame. The need for knowledge of qualitative and quantitative dynamic behavior related to the field of use determined major investments and extensive research in large laboratories. Research on an asynchronous motor with a power of 1.1 kW with variable parameters proved that, between the idle running simulated and experimentally determined values, the errors do not exceed 3.97%. These results authorize the conducted research, providing qualitative and quantitative correct simulations for the rated regime.
