Small, high-speed BLDC motors usually have very low inductance compared to a conventional BLDC motor. In this case, the bipolar PWM cannot be used. A solution can be achieved with higher frequency, ...

The PID speed control can be implemented in firmware or hardware logic. Figure 18 and Figure 19 showa closed-loop implementation in hardware and firmware respectively.With closed-loop speed control, ...

Precise setting of a speed profile can be programmed into the built-in non-volatile memory (NVM). Operating from a supply voltage ranging from 5.5 to 27V, the device includes selectable closed loop or ...
