Manufacturing Cage Rotors TRIZ Cases
- Cage Rotor Conductor Bar Fixation by Local Annealing and Compression
Soft-annealed conductor bar sections are compressed in rotor slots to stop oscillation, ease insertion, and support automated cage rotor production.
- Electrolyzed Copper Squirrel Cage for Reliable Asynchronous Motors
Copper electrolysis forms guide bars and end rings without casting or welding, cutting energy use while improving purity and motor reliability.
- Squirrel-Cage Rotor Retention for Thermal Expansion and Full Bar Cross-Section
Retaining conductive bars through the shorting disc preserves current cross-section, absorbs thermal expansion, and avoids screw stress and wear.
- Rotor Cage Transition Region for High-Speed End Ring Stress Relief
Transition regions with increased cross-sections reduce stress concentration at bar-ring joints, preventing premature failure during high-speed operation.
- Hybrid Rotor Bar Assemblies With Aluminum Shims
Lining copper rotor bars with aluminum shims secures the assembly, increases starting torque, and reduces material cost compared to steel alternatives.
- Cage Rotor Bar Notch for Thermal Shrinkage Accommodation
Notched bar ends in a cage rotor bend radially to follow short-circuiting ring shrinkage, maintaining low contact resistance and reducing mechanical stress.
- Skewed Lamination Pack with Bent Conductor Bar Locking
Bending conductor bar ends locks a skewed lamination stack, reducing magnetic cogging and noise.
