Other Parts Discussed in Thread: MOTORWARE
Tool/software: Code Composer Studio
Hi,
I am using motorware 15 stack , a resolver feedback ( using a ti resolver to digital conversion kit ) with a PMSM as my setup. I am using Lab5a with resolver electrical angle through SPI. This setup was working well .
When I ramped motor rpm near to base rpm ( around 6000rpm at 400Vdc without field weakening), I have noticed that the motor is producing a jerk with a higher negative current ( around -250Adc). Few rpms before that point the motor is starting to produce a hum and then producing the jerk with negative current. At that time inverter IGBT drivers are getting trip.
Have anyone of you experienced this ? what should be the courses for this and how can I solve this?
Thanks
