01 / Context
Overview
A conventional three-phase induction machine was reverse-engineered and converted into a five-phase machine to create a dedicated multiphase-drive research platform. The work started with geometry extraction and a baseline electromagnetic model in Ansys Motor-CAD, then moved to winding synthesis and finally to physical stator rewinding.
The five-phase winding was designed from the available slot/pole combination using star-of-slots reasoning and fractional-slot constraints. Conductor allocation between neighboring slots was adjusted to improve slot-fill distribution while preserving the intended phase displacement and practical manufacturability.
My work
- Reconstructed the machine geometry and generated a baseline Motor-CAD model.
- Designed the five-phase fractional-slot winding and verified the winding layout.
- Optimized conductor sharing and slot fill before physical rewinding.
- Integrated the rewound machine into the experimental drive test bench.
02 / Approach
Methods & diagrams
Machine Reconstruction
Mechanical and electromagnetic geometry was extracted from the original motor and reproduced in Motor-CAD.
Winding Synthesis
A five-phase winding layout was developed from slot/pole geometry using star-of-slots and phase-belt constraints.
Experimental Rewinding
The stator was physically rewound and prepared for operation with the five-phase inverter and controller platform.
