高惯性负载在工业中大量存在，其中大多数是具有双笼转子的直接在线起动器型感应电机。由于其较高的启动时间，转子中较高的功率耗散使转子磨损并最终被破坏。本文提出了一种新的起动方法，利用逆变器使电动机快速、平稳地起动。在达到其稳定状态后，电动机被切换以从电网汲取功率，同时逆变器被用于控制从电网汲取的无功功率。从而允许电机以单位功率因数甚至超前功率因数运行。
High inertial loads are abundant in the industry and most of them are direct on line starter type induction machines with double cage rotors. Due to their higher starting time higher power dissipation in the rotor makes the rotor wear out and eventually gets destroyed. A new starting method proposed herein makes the motor start quickly and smoothly by using an inverter. After reaching it's steady state the motor is switched to draw power from the grid meanwhile the inverter is utilized to control the reactive power drawn from the grid. Thus allowing the motor run with unity or even leading power factor.
