We are working on a Medical Respirator equipment, for which we need to control the BLDC motor up to 60,000 RPM.
To generate a speed of 60000 RPM, Space Vector Modulation PWM waveform main/base frequency shall be 4 KHZ.
To have a smooth ripple free current/torque we need carrier frequency (Space Vector Modulation) shall be around 100kHz.
Is it possible to generate this with coretex M4 or other controller
- 100 khz carrier frequency by SVM (Space Vector Modulation)
- Also at same time, it has to work on sensor less FOC as a close loop feedback for speed & to get optimum torque.
- For this it shall probably have current feedback from 2 motor coils.
- Also some other functions to satisfy respiratory system
Please provide input
