| Abstract |
Inverter output harmonics create great
amount of losses in solid rotor induction moton. The
output filter of the PWM-inverter is introduced to
smoothen the inverter output wave forms. Thus the
efficiency of the solid rotor induction motor will increase
remarkably. The filter is designed so that it also
compensates the magnetising current of the motor.
Therefore the inverter output current is limited. The
paper presents the characteristics of a 16 kW, 13500
l h i n solid-rotor induction motor drive for a robotic
milling machine application. |
