Need information regarding sensorless FOC of PMSM motor

[pratayay123]

Dear Team,

Need information regarding the below queries.

1. which sensorless algorithm is better (SMO/PLL) for FOC control of IPSM motor.

2. Is there any sample Sw for HFI control of IPSM motor for low speed.

Thanks,

Pratyay

Hello,

1. which sensorless algorithm is better (SMO/PLL) for FOC control of IPSM motor.

We do not have it. We use BEMF observer with Angle tracking observer.

2. Is there any sample Sw for HFI control of IPSM motor for low speed.

I do not have knowledge of any.

Best regards,

Peter
