Part Number: DRV10866EVM Other Parts Discussed in Thread: DRV10866 Hi,
I am using the DRV10866EVM as a debug setup for my motor control. I am having start-up issues with one of two motors. The first motor has a phase-phase resistance of about 6.3 ohms…
Part Number: DRV10866EVM Other Parts Discussed in Thread: DRV10866 Hi,
I am using the DRV10866 in a closed loop application. The current limit resistor is the default 3.8k. With a light inertia the motor starts up quickly and robustly. With a higher inertia…
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. …
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 of…
Part Number: DRV10964 Other Parts Discussed in Thread: DRV10866 , , TPS22860 , DRV10866EVM , , DRV10963 DRV10866 has this feature. It is not clear to me from reading the datasheet that the DRV10964 has this feature. IOW, does the PWM pin need to be pulsed…
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…
Part Number: DRV10866 Other Parts Discussed in Thread: , DRV10963 Using the DRV10866EVM (evaluation module board with motor provided in the kit) and a EZ MSP430 Launchpad (the USB dongle with separable target board.) I jumpered Vcc, Gnd, and a motorEnable…
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
