But it is not as simple as it sounds but informative. Expect to basically forget your original project for some time while building this one. | |
| Jan 7, 2020 at 15:14 | comment | added | DKNguyen | @user165514 Because, different things are designed for different uses and if its too specialized you can't use it for something else. Just because a cement mixing truck is a truck with 4 wheels doesn't mean it can be used as a general purpose truck. Too specialized. Read the first sentence of the datasheet and look at the highly specialized inputs on the block diagram which are irrelevant for a motor. | |

| Oct 12, 2017 at 2:24 | comment | added | user165514 | Thank you for your comments! Jack, I will check out your link tonight. The UC1825 has outputs for 3 phases? Why can I not drive the 3phase BLDC? Also, if a dsp generates the sinusoidal wave, can I use 3 half bridges as an inverter and avoid the UC1825? | |

| Oct 11, 2017 at 20:16 | comment | added | Marko Buršič | "Unfortunately, I am forced to use the UC1825 pwm controller chip". This is nonsense. Make an investigation around FOC - Field Orientated Control with PMSM. BLDC isn't even the right choice for your problem and forget the UC1825, there's nothing you can do with it. | |
