Study on energy-saving AC variable frequency speed-governing experiment system based on DSP control

An energy-saving AC variable frequency speed-governing experiment system, based on the structure of two motors at the same shaft realized by DSP control, is introduced in this paper, which controls motor set at the same shaft run on different frequency and realizes variable frequency speed-governing of little load power-consumption based on the regenerate power feedback of motor group. Combining with the technology of space vector PWM, digital variable frequency speed-governing experiment system is realized based on TMS320LF2407A DSP.
