Motor Parameters Estimation/Adaptation TRIZ Cases
- Force-Multiplier Torque Calibration for Electric Tool Accuracy
Stored torque tester data lets an electric tool compensate force-multiplier wear and manufacturing error to avoid over-tightening or loosening.
- Oscillating Motor Frequency Control for Resonant Blade Drive
By measuring motor resonance after power-off and storing it for restart, the controller keeps hair clipper blade drive near peak efficiency.
- Motor Servo Rigidity Tuning Using Frequency Response Measurement
Frequency-response measurement lets motor servo control set the highest safe rigidity faster, reducing adjustment time and avoiding oscillation damage.
- Motor Inverter PWM Switching for Low-Loss Torque Control
Dynamic switching between flat and normal PWM cuts inverter losses while preserving precise torque and managing thermal load.
- Electric Motor Auto-Tuning Using Virtual Damping Feedback
Closed-loop speed feedback and virtual damping estimate motor inertia and friction accurately, reducing tuning complexity and rotor risk.
- Dynamoelectric Machine Ripple Compensation via External Correction Data
External correction data compensates motor speed and torque ripples from cogging and tolerances without added encoder storage.
