DC Motor Speed/Torque Control TRIZ Cases
- Motor Winding Heater Control Using Smart Motor Controller
Smart motor controller applies current to windings for heating, eliminating dedicated heater devices and reducing system complexity.
- Differential Pressure Sensor for Aviation Fuel Filter Monitoring
Electronic transducer measures differential pressure across fuel filters, triggering alarms when excessive pressure indicates contamination risk.
- Motor Average Current Determination via PWM Duty Ratio
A method calculates motor average current by combining phase currents with duty ratios.
- Negative Rail Current Driver for Torque Motor Power Balance
A current drive circuit supplies controlled current to inductive loads from a negative voltage rail using positive input signals.
