Part Number:DRV10983-Q1
Hi,
Recently I had tuning lot of motor for my customer. I have some question need to declare.
1. Why some motor phase current have is beautiful sinusoid waveform, but some motor phase current is distortion. Which motor parameter will cause that.
2. Why some motor very easy to tuninig. For example it can follow the speed command in many Kt value.
And some motor just can run in specific Kt value. I had one motor just can run well in Kt = 33 , if change to 30 or 36
will cause BMEF fail. If Kt is so sensitive it can't run in different temperature. And the production rate will slow down.
So I want to know which motor parameter could I suggestion to motor company to improve that.
3. My customer have a motor need to spin in 300RPM and the speed cmd is 10%. The motor is used for lidar the inertia is high. In production line they found when force shake the motor,
It will cause BMEF fail. Whether DRV10983 suite this kind application scenario. The motor is 6 pole, Phase resistor is 1.8, Kt is 55.2.
Thanks
