Thanks for the info.
So you tell me this scheme is not going to help me to control a BLDC motor.
Could you advise me some type of information or documentation where to start the design of a control for a BLDC motor?
Hi,
My two cents about what you should look for to make your life easier:
-A Microcontroller with hardware support for PWM generation of at least 3 phases. If it is able to insert dead-time between on leg high and low side transistor, much better, since the driver you use doesn´t do this.
-If you plan to control current cycle by cycle, one able to link Analog to Digital conversions with PWM time base.
From a BLDC motor control perspective, those two are the 2 main characteristics I can think of right now, if you plan to do simple six-step control.
If you plan something smarter like FOC, you need something powerful enough to do the calculations needed.
In Microchip terms, the BLDC motor control peripheral is called "POWER CONTROL PWM MODULE", look for a part with it, like, for example PIC18F4431.
Note this one would probably be too slow for FOC.
