Sensor-less Drive for BLDCM or PMSM



Dear Sir/Ma’am,

I am interested in the Sensor-less drive for PMSM announced by ST Micro.
The technology is called ”STM32 ZeST”.
I contacted ST Micro's engineering trading company, but they said they didn't know the details.
Is there detailed documentation on this technology? We are considering whether it can be applied to drive PMSM, which is being considered for industrial applications.

Best regards, Jun

Hi,Geal A

Not resolved yet. I contacted ST Micro's office through a enginnering trading company. However, I couldn't get a detailed answer. This is because sensor-less materials are not yet ready.
Best regards, Jun
