Synchronous Generators TRIZ Cases
- Polyphase Machine Star Windings Negative Mutual Inductance
Negative mutual inductance between star windings cancels positive coupling to eliminate interfering currents and heat losses from interlaced inverter control.
- Hybrid Excitation Rotor for Field Control in Permanent Magnet Machines
Stationary excitation coil establishes magnetic flux through low reluctance rotor elements to combine with permanent magnet radial flux.
- Stator Windings with Radial Tilt for Compact Generator Design
Tilted winding heads in a three-phase stator arrangement resolve assembly difficulties while minimizing copper usage and reducing axial dimensions.
- Generator Rectifier Assembly Housing Openings for Bolt Access
Segmented rectifier housing openings provide direct tool access to tighten bolts securing springs, resolving assembly complexity in generator units.
- Brushless Alternator Yoke Joint Design
Integrally formed yoke structure positions holding member away from magnetic circuit path, reducing magnetic resistance and stress concentration at joints.
