Induction Machine (IM) and PWM Drive circuit, with mechanical fan load.
Induction Machine (IM) and Variable Frecuency Driver (V/f type) starting from the DC bus feeding the power mosfets, which are driven using PWM.
For a given motor the DC power supply or battery must be adjusted to the rms line voltage times square root of 2. and the V_to_f gain must also be adjusted to Vrms/nominal freq.
After that, only the frequency imput needs to be changed according to the desired speed or operating point
