I hope this message finds you well. I am currently working on a plant model of an IPMSM with a FOC algorithm implemented. My objective is to transition my plant model from a star configuration to a delta configuration.
Here's a brief overview of my situation:
- I have utilized the Simscape Electrical Motor model for my simulation, a snapshot of which is attached. I have changed the motor model from Wye wound to Delta wound.
- During simulation runs, I've encountered a discrepancy in the achieved torque values. While aiming for a torque of 60 Nm, I'm only attaining approximately 25 Nm.
- I undertook an approach to address this by dividing my line current by the square root of 3 (√3) and give it as feedback to (FOC) 'Park transform' block to derive feedback currents, which increased my torque output to 49 Nm. However, this still falls short of my target torque of 60 Nm.
Given the complexity of transitioning from a star to a delta connection and the apparent lack of pertinent examples or content online, I am seeking guidance from the experienced members of this community. Could you kindly assist me in refining my approach to accurately transition my model and achieve the desired torque output? Any insights, suggestions, or references to relevant resources would be greatly appreciated.
Thank you for your time and expertise.
