OL OF SYNCHRONOUS MOTOR BY USING VARIABLE FREQUENCY DRIVES



ABSTRACT :

A novel open-loop speed control method for induction motors that provides high output torque and nearly zero steady-state speed error at any frequency is presented. The control scheme is based on the popular constant volts per hertz (V/f) method using low-cost open-loop current sensors. Only stator current measurements are needed to compensate for both stator resistance drop and slip frequency. The scheme proposed fully compensates for th..................[:=> Show Contents <=:]

4. Drop in speed from no lad to full load is small.
Fig. Shows the torque-developing characteristic of every motor: the Volts per Hertz ratio (V/F). We change this ratio to change motor torque. An induction motor connected to a 460V, 60 Hz source has a ratio of 7.67. As long as this ratio stays in proportion, the motor will develop rated torque.
