Part Number: DRV10866EVM Other Parts Discussed in Thread: DRV10866 I have bought the above evaluation board, however it did not come with the BLDC motor included...the second one sent out did not come with the motor either.
The DRV10866_BOM that I downloaded…

Would like to know if there is any DRV____ evaluation module with the (optimal) closed loop MCU controller included…
Other Parts Discussed in Thread: DRV10866EVM , DRV10866 Hi My customer is using DRV10866EVM. He uses motor whose pole pairs is 4.
He has a issue. When motor speed is high, FG waveform is missing teeth. I think it exceeds RPM spec on which DRV10866 can…
Other Parts Discussed in Thread: DRV10866EVM , DRV10866 Hi My customer is using DRV10866EVM. He uses motor whose pole pairs is 4. He sets FGS=1. Could you let me know how to calculate max RPM value? He has a issue. When FG frequency exceeds 700Hz, Motor…
A duty cycled PWM signal DOES start and turn a Nidec 10S. Whereas a constant high PWM does NOT. Which might contradict what you say, just to be clear. And to repeat myself, in my interpretation, the datasheet for the DRV10964 does not clearly say that…
Hi Micheal,
Thanks for the fast reply.
The supply voltage is 3.7V and I kept all the default component values on the DRV10866EVM board, so the CS resistor is 3.8k setting a current limit of 820mA. The motor I'm using has a phase to phase resistance…
Motor Phase to phase resistance 20Ohm
VCC 5V - USB powered.
Rcs?
If you are talking about R6 in DRV10866EVM (which I use now) manual says 2.6KOhm

Are these all the EVMs currently active/available for 5V Sensorless BLDC Motors (3-Phase) under $50 or are there others?
