Association With Control/Drive Circuits TRIZ Cases
- Jog Knob Virtual Mass Control for Smoother Haptic Rotation
Closed-loop PCB stator control simulates rotational inertia in a jog knob, restoring smooth haptic feel in lightweight camera controls.
- Stator Neutral Fuse Cutoff for Inverter Short-Circuit Protection
A heater-integrated fuse at the stator neutral cuts the circuit after inverter short-circuit detection, reducing relay resistance and power loss.
- Externally Excited Synchronous Machine Rotor Demagnetization Circuit
A shared protection circuit disconnects the rotor coil from the rectifier, absorbs stored energy, and enables reliable demagnetization.
- BLDC Motor Winding Layout for Compact High-Power Tools
Parallel tooth windings and configurable stator connections raise BLDC motor power density in compact power tools while improving efficiency.
- Inverter Cover Rib Layout for Noise and Water Drainage
A labyrinth rib layout stiffens the inverter cover to suppress vibration noise while guiding water off the surface to prevent accumulation.
- Vehicle Drive Layout With Shared Cooling for Compact Two-Axis Packaging
Overlapping the inverter and output member enables a compact two-axis drive layout while linked coolant channels cool both the motor and inverter.
- Motor-Mounted Winch Contactor Layout for Protected Wiring
By integrating the contactor around the winch motor, this case cuts external wiring, speeds installation, and shields connections from weather.
- 3D Inverter Capacitor Layout for Shorter Bus Bars
Columnar capacitor units and plate bus bars shorten inverter current paths, cutting inductance, weight, heat, and EMI.
- Inverter Capacitor Structure With Circumferential Bus Bars for Low Inductance
Columnar unit capacitors placed at equal distances and linked by circumferential bus bars lower inverter inductance, EMI, weight, and noise.
- Harmonic Drive Servomotor Feedback for Backlash Accuracy
Sensor feedback corrects harmonic drive output angle errors, cutting backlash and preserving servomotor precision in a compact reducer.
- Potting Boat Heat Sink With Wire-Retaining Cooling Structure
Cooling fins and a recessed wire path help a potting boat dissipate PCB heat in power tools while preventing electrical shorts.
- Stator Press-Fit Annular Members for Compact Vehicle Motor Frames
Annular carbon steel members let a stator be press-fitted into an aluminum frame without damage, improving holding force and reducing motor radial size.
- Dual-Wedge PMG Braking with Shear Shaft Fault Decoupling
A shear shaft and dual wedges decouple the prime mover and brake a permanent magnet generator to zero speed during short-circuit faults.
- Semiconductor Module Power Wiring Layout for Compact Motor Electronics
By mounting module electrodes on shared power wiring, this case cuts motor electronics wiring space, impedance, and inductance.
