Abstract :
Fuji has developed a vector control voltage type inverter for driving induction motors at variable speeds. This machine tool main shaft drive system incorporates a digital signal processor (DSP) to provide all digital control and DC current component control method. This approach features compact design and high performance. Experimental results are presented.<>
