Dynamo-Electric Machine Testing TRIZ Cases
- Machine Fault Detection via Drive Power Spectrum Analysis
Electrical power spectrum analysis reveals early machine faults and their location without vibration sensors, reducing unplanned repairs.
- Motor Efficiency Investigation Using Nameplate Data and Model Lookup
Nameplate-based motor type identification combines measured data lookup or nominal-efficiency simulation to speed loss estimation without sacrificing accuracy.
- Motor Efficiency Investigation Using Nameplate and Lookup Data
Nameplate-based motor type matching combines measured efficiency tables with model simulation to speed loss estimation without sacrificing accuracy.
- Hairpin Scan Sorting for Insulation Damage Detection
An electrical scan brush and closed-loop feeder sort hairpins with damaged insulating film in real time, cutting manual inspection time and cost.
- Three-Phase Motor Testing Without Mechanical Locking
Single-phase excitation tests a three-phase motor by regulating current at two terminals, avoiding mechanical locking while preserving test accuracy.
- Motor Emulator Control for Low Switching Loss and Current Tracking
By matching the motor driver switching frequency, this motor emulator cuts switching loss while maintaining accurate inductor current tracking.
