Electric Motor Control TRIZ Cases
- Motor Actuator Relay Sequencing Prevents Counter-EMF Damage
Sequential solid-state relays interrupt battery power inside a motor actuator safely.
- Drive Circuit EMI Filter and PFC Choke Configuration
A drive circuit integrates an EMI filter with series capacitors and a PFC choke to reduce conducted electromagnetic interference.
- Shielding Layer and Conductive Elastomer for Common-Mode Noise Suppression
A shielding layer and conductive elastomer connect a switching device terminal to ground.
- PMSM Controller Angle Correction for Step-Out Prevention
A permanent magnet synchronous motor controller adjusts estimated magnetic pole angles to maintain torque during acceleration.
- Sensorless Motor Control for Inductance Estimation
A motor control method adjusts voltage components to drive a synchronous motor, enabling precise rotor position estimation.
