摘要: A system for starting synchronous motor from a pulse-width-modulated static inverter without using rotor position or speed measurements. The monitors supply current to the stator and derives relationship between that magnetizing flux. utilizes narrowband filter is tuned pass only currents fundamental component whose frequency changes with variations in speed. Furthermore, reduces excitation provided after certain value of line voltage sensed.
