Hello Madam/Sir,
@Cristiana SCARAMEL
We are developing a PMSM motor drive for an industrial application. This application is for Sugarcane Juice machine where we require to provide instant high torque for a shorter duration.
I have developed a PMSM drive using the STSPIN32F0 controller. Drive is able to provide some 14 Amp loading for a small or a medium sized sugarcane on the motor instantly. But incase of a thicker sugarcane it may be requiring more Amps. But at that time, controller speed reduces significantly and gives a Speed Feedback or OverCurrent faults.
Motor parameters:
Pole Pairs: 2
Nominal Voltage: 36V
Max Current: 25A
Nominal Speed: 1400 RPM
Rs: 0.48 Ohms
Ls: 2.5 mHenry
Bemf Constant: 17 KRPM/Vrms
Control Technique: 3 Shunt Sensorless FOC
I have few questions in which I require your guidance.
- Does this controller STSPIN32F0 support this power rating? (Approx 900 Watt)
- Should I run the motor in Torque Control Mode or Speed Control Mode?
- Do I need to use 2 different PI loops? one for starting and another for Running conditions?
- How do I tune the Motor for this instantaneous Torque application? Please share a guide document if it is possible?
- I am Sharing the STMCX file for your reference. Let me know if you require any more information for the same.
Awaiting your reply soon.
Thank you
