I am giving 12Volts power supply to the evaluation board which is integrated with the microcontroller and MOSFET's bridge driver and now how can I know how much voltage is supplying or passing through the stator coils in the motor?
Thank you FvM for the reply. In the evaluation board documentation it is written VSD upper threshold voltage value should be given 24V and lower threshold voltage value 5V by implementing software in user interface which is provided by the microcontroller company. So Can I think the voltage is passing through the stator is 5V to 24V between?
The datasheet BLDC application circuit shows a current sense resistor in the negative bridge supply. The shunt voltage is amplified by the operational amplifier in the microcontroller and processed by the ADC. There should be a software current control loop.
Isn't the evalboard shipped with a demonstration firmware for BLDC application?
