Electronic Commutators TRIZ Cases
- Motor Start-Up Dead Time Control for Back-EMF Noise Suppression
Motor speed feedback sets start-up dead time to limit back-EMF current, reducing noise and protecting circuit components.
- Encoderless Electric Machine Control With Torque-Gated HF Injection
High-frequency rotor position signals are enabled only above a torque threshold, cutting loss, heating, and noise in encoderless motor control.
