Combining Hall interrupts with fixed time interrupts improves low-speed BLDC speed calculation and control in hand-held power tools.

Virtual current loops and virtual capacitors help inverter-based VSMs stay synchronized despite grid voltage sensing errors and delays.

Predefined application-specific macros narrow parameter choices, making industrial device commissioning faster and easier for non-expert users.

Hardware lookup tables convert Hall sensor readings into PWM commutation patterns within fixed timing, avoiding CPU interrupts.

When motor power is cut in emergencies, a secondary drive supply keeps inverter switching active so short-circuit braking can still be applied safely.

Torque feedback and phase limiting suppress rotation sensor offset effects in AC motor control, reducing unintended torque and imbalance.

Converts eccentric motor drive data into resonant haptic waveforms by preserving envelope trends, reducing data creation effort and chatter.

Frequency and amplitude mapping adapts steady and transient waveforms to linear motor characteristics for stronger, safer haptic feedback.

Existing eccentric motor drive data is converted into higher-frequency haptic waveforms by preserving envelope trends, reducing app data creation burden.

Slew-rate conditioning of motor voltage or current before an active short cuts transient peaks, protecting magnets and the DC link capacitor.
