Part Number: DRV10963
I have the drv10963dsnr device that I want to use to control common hard drive platter bldc motors but I am having issues to get it to do anything. The motor specs are, Rm = 5ohms, Lm = 750uH but I do not know Kt I am using the schematic on page 19 of the data sheet and applying a PWM signal of about 40kHz with a duty cycle range of 15% - 90%. I am missing something. I have attached some images. Sorry for the large image files.
