| Abstract |
Dynamic performance analysis of an inverter-fed induction motor driven by the voltage-current pattern (V-I pattern) control for power saving is presented. The V-I pattern control is a control method for improving motor efficiency. The method can be applied to an induction motor having a changeable or on-and-off load, and it saves energy when the motor runs in moderate and light load condition. To create a more sophisticated inverter-motor system it is necessary to investigate the dynamic performance of the motor under the V-I pattern control both theoretically and experimentally. In this paper, we discuss the motor performance using a transient equivalent circuit with consideration of time-harmonics which affect iron loss and deep-bar-rotor copper loss, and the simulation is carried out by using the spiral-vector method. The simulation and experimental results show that the proposed efficiency-improving motor driving system is useful in power-saving applications. |
