At SOLWIT Engineering and Consultancy, we bridge the gap between cutting-edge electromagnetic theory and rugged, real-world hardware. We offer a rare combination of in-house manufacturing for compact, high-precision applications and world-class engineering consultancy for massive industrial powertrain systems. Our expertise spans both traditional Radial Flux topologies and next-generation, high-density Axial Flux motor designs.
Our Specializations & Core Topologies
1. Axial Flux PMSM — Our High-Performance Speciality
Axial flux technology represents the cutting edge of electric machine design. By directing the magnetic flux parallel to the rotation axis, we unlock extreme performance advantages:
- Unmatched Torque Density: Delivers up to 2–3× the torque-to-weight ratio of conventional radial motors — ideal for space-constrained environments.
- Ultra-Compact Aspect Ratio: A distinct "pancake" geometry that integrates easily into wheel hubs, tight engine bays, or compact robotic joints.
- Maximum Efficiency: Shorter coil ends significantly reduce copper losses, offering exceptional efficiency across the entire speed range.
2. Radial Flux PMSM — Standard & Custom Topologies
For reliable, cost-effective, and highly versatile motion control, we design optimized radial flux configurations:
- Surface Permanent Magnet (SPMSM): Engineered for high dynamic response and excellent low-speed torque characteristics.
- Internal Permanent Magnet (IPMSM): Tailored for high-speed operation, leveraging reluctance torque and robust mechanical retention of the magnets to prevent demagnetization under centrifugal stress.
