AIONSTROMThe physics haven't
changed. The switching
frequency has.
Ultra-compact motor control for machines that fly, walk, and drive. Aionstrom integrates the controller inside the motor - no drive box, no cabling, no wasted weight.
500 kHz makes true motor integration possible.
40 – 60% smaller
The controller lives inside the motor - no external drive box.
Shared cooling
Motor and controller share one thermal system instead of two.
+15% efficiency at partial load
High switching frequency shrinks magnetic losses where it matters most.
THD < 5%
Cleaner power output with minimal EMC filtering needed.
Fewer harmonics reach the motor
500 kHz switching pushes harmonic content far above the motor's electrical bandwidth, so windings and core see cleaner current - less parasitic heating, less acoustic noise, and a longer motor lifetime.
What integration changes
Lower system cost - eliminates the drive box, cabling, separate enclosure, and installation labour.
Higher reliability - fewer connectors, fewer interfaces, fewer failure points.
Faster integration - customers receive a single unit, ready to mount.
Aionstrom vs. conventional 20 kHz controllers.
| Metric | Conventional | Aionstrom | Improvement |
|---|---|---|---|
| Efficiency | 92 – 95% | 97 – 99% | +2 to +7% |
| Power density | 3 – 5 kW/kg | 10 – 15 kW/kg | +200 to +300% |
| System volume | Baseline | −60% | −60% |
| Torque ripple | 15 – 25% | < 5% | −75% |

Innovative motor design, not just faster switching.
500 kHz control unlocks motor topologies that conventional 20 kHz drives can't fully exploit - starting with magnet-free reluctance motors, and extending across our full portfolio of efficient designs.
No magnets, no rare earth materials, rugged construction. Stable at extreme temperatures with fault-tolerant operation - and at 500 kHz, torque ripple drops to where SRM finally competes with PMSM on smoothness.
