Abstract :
The transient behavior of a permanent magnet synchronous motor is analyzed, and a method is proposed to improve its starting performance. Three banks of capacitors are connected in series between the three-phase source and the motor. A stability analysis is performed to demonstrate that a range of capacitance exists that is useful for improving the motor dynamics. Motor line starting is analyzed using the calculated value of capacitance, and several simulation and experimental runs are discussed.<>
