Control of a Permanent Magnet Synchronous Machine (PMSM)
You have described specifically how you have been unsuccessful. I suspect that the motor is drawing more current than you source can supply. The only way you can successfully operate open-loop is to start the motor at a very low voltage and frequency, 1 or 2 Hz. Once the motor is operating at a low speed, increase the voltage and frequency together at a controlled rate. All speed changes must be made at a controlled rate. The motor will draw a higher current just accelerating its own inertia if the rate of frequency increase is too great. If the frequency is reduced too quickly, the motor generate current back into the supply in braking the motor to a lower speed, so the rated of frequency reduction must also be limited.
