finding a motor driver to 0308 FAULHABER's motor

hello,

I am trying to find a motor driver to the FAULHABER 0308 sensor-less BLDC motor that i am using.

[View:/cfs-file/__key/communityserver-discussions-components-files/38/0308_5F00_B_5F00_DFF.pdf:1230:0]

i want to be able to spin the motor in 40000 rpm with a motor voltage of 5.5V

i have already purchased your DRV10963 motor driver , but it didn't spin the motor well.

i tried all the parameters there but it didn't reached even close to my desired RPM. i think that the problem was that the driver was not able to pass from open loop to closed loop because the BEMF in low RPM was hard to read.

do you have any recommendations for another motor driver that will be to handle that motor ?

thanks - SAM
