Dynamo-Electric Converter Control TRIZ Cases
- Stepping Motor Homeward Movement Detection for Cutting Abnormality
A homeward movement detecting unit measures stepping motor driving amount to identify operational faults during reciprocating motion.
- Dual Camera Bar Code Reader with Fold Mirrors
Fold mirrors align a global shutter and rolling shutter camera to resolve the trade-off between high-density 2D resolution and moving 1D distortion.
- Variable Frequency Drive Motor Brake Failure Control
Controller detects brake failure and interrupts power to drive the motor at faster speeds, enabling safe controlled lowering of suspended loads.
- Stepping Motor Drive Controller Torque Control
A drive controller manages stepping motor rotation through dynamic torque signal adjustments during instrument pointer sweeping operations.
- Tapered Biplanar FSL for Low Insertion Loss
A tapered biplanar transmission line structure modifies impedance profiles to maintain low insertion loss for weak signals.
- Stepper Motor Stall Detection via Differential Back-EMF
A stall detection sensor measures back electromotive force differentially across commutation phases to identify motor stalls.
- Profiled Magnetic Ends for NLTL Demagnetization Reduction
Curved end surfaces on hollow cylindrical ferrite elements prevent flux divergence, reducing microwave waveform attenuation and improving RF energy conversion.
- Stepping Motor Control Device for Smooth Acceleration
A stepping motor control device switches between advance angle and voltage control states to manage rotation speed across a dynamic range.
- Head-Up Display Motor Control for Heat Reduction
A head-up display motor control apparatus adjusts drive current to maintain reflector position and movement.
- Lever-Actuated Wheel Rotation in Multi-Player Gaming Machines
A gaming machine uses a central controller to rotate and stop a wheel based on lever activation from multiple terminals.
- Stepping Motor Rotor Position Detection via Magnetic Saturation
A driving processor applies detection pulses to motor coils and measures resulting current values to determine rotor position.
- Elevator Counterbalancing System Backlash Compensation
Motor drive applies bidirectional torque to detect shaft backlash before brake release, eliminating elevator rollback and vibration.
- Power Conversion Device Step-Out Detection via Induced Voltage
A power conversion device detects motor step-out by analyzing induced voltage frequencies during free run states without position sensors.
