1. Control Diagram
IPM sensorless FOC mode (applicable for C2000 V2.04 and above)
※ PM Sensorless FOC control is the control method dedicated for IPM, it uses the high salient
pole characteristic (Lq > Ld) of IPM to detect the positions of NS magnetic poles. By doing this,
it calculates the motor’s rotor position at low-speed frequency.
