Hi,
we are looking for some PMSM Motors to allow students to design their own nonlinear control algorithms using a 24V power converter. Since most 24V machines are servo motors and therefore typically dont saturate i wondered if this one might. Has anyone experienced this so far or even measured flux maps for this machine?
Furthermore: Whats the diameter of the drive shaft? 8mm like the other ones?
best regards
Johannes
Dear Johannes,
thank you for reaching out to us. The motor LVBLDCMTR should have a shaft diameter of 8mm. I need to check with our C2000 MCU team if there are any details on the saturation current or flux maps. I will come back to you.
Just curious: Are you using our our C2000 real-time MCUs for your nonlinear control?

Thank you very much for the answer. Looking forward for any additional information / datasheet and hopefully flux maps etc.
Are the windings of the machine connected in star or delta?
We use a system we developed ourselves.

Dear Johannes,
thank you for the info. It's an interesting development system. When you plan a redesign, would you be interested using TI precision A/D converters, isolators, etc.? We'd be happy to support you here.
Regarding the LVBLDCMTR. We don't have any more data on the motor.
For our testing of low-voltage 3-phase inverter EVMs, we use the below servo motor from Teknic, I've added the data we have for that motor.
Link to the low-voltage servo motor: https://www.ti.com/tool/LVSERVOMTR
The motor parameters are star equivalent, per phase, and estimated with C2000 InstaSPIN-FOC, the shaft diameter is 9mm.
