Part Number:DRV8332
Hello All,
Another question regarding the DRV8332: we have the driver hooked up to run a 750 W brushless hub motor. We tried supplying 24 V as well as 36 V to PVDD, but both times the phase voltages were reduced to 10.6 V on the output. The motor won't draw any current.
Our third test supplied 4 V to the motor, and it drew roughly 2 A from the power supply in order to spin. Raising the voltage to 5 V or higher caused the motor to stop immediately. Does anyone know why the voltage is so much lower than PVDD, or why the motor will run only at low voltages?
Any help is much appreciated.
