WebIn order to maintain torque at a speed other than its rated speed, you need to adjust the frequency in proportion to the voltage. If you want to do it right, you rectify the AC into a DC bus and then use IGBTs to chop up the bus (using PWM) to generate an AC waveform at the frequency and average voltage you need.
