Electric Motor Control TRIZ Cases
- Shift Range Control Device With Homogeneous Calculation Signals
Multiple controllers acquire detection signals and determine identical calculation values to maintain consistent motor drive during partial sensor faults.
- Inverter Failure Detection via Dual Drive Mode Current Analysis
Motor control unit detects inverter faults by switching upper and lower arm states to compare phase currents against defined thresholds.
- Variable Frequency Drive Self-Check Controller
A variable frequency drive controller evaluates switching devices and sensors to detect faults before motor startup.
- Steering Control Device Asymmetric Microcomputer Design
Dual microcomputer steering control systems use distinct manufacturing origins to prevent synchronized failures.
- Motor Control Device Inverter Switching for Redundancy
A motor control device uses an inverter selector to route PWM signals to multiple inverter units based on operational status.
- Current Detection Apparatus Temperature Compensation via Segmentation
A current detection apparatus uses segmented correction resistors to generate candidate voltages for real-time load monitoring.
- Motor Control Device Using Adaptive Observer for Inertial Load Estimation
An adaptive observer calculates estimated inertial load values from motor output commands and actual outputs to stabilize control systems.
- AC Rotary Machine Control Device Resistance Error Compensation
A control device calculates estimated resistance values by adding a correction value to a basic estimate derived from external temperature.
