Sea
Quiet slotless BLDC propulsion motors up to 50+ kW, paired with seal-less pumps for cooling and transfer on USVs and UUVs.
For surface and underwater vehicles
-
Propulsion and BLDC motors
Main propulsion, vectored and station-keeping BLDC motors, and winch and actuation drives, on a slotless architecture for low acoustic and EM signature.
-
Cooling and transfer
Seal-less pumps for engine, battery, and payload cooling loops, plus bilge, fuel, and ballast transfer.
-
No shaft seal
The magnetic coupling design removes the shaft seal, the primary leak path and failure mode on unmanned vessels that run for weeks without a crew to service them.
USV and UUV parameters
| Parameter | Propulsion and BLDC motors | Fluid and thermal |
|---|---|---|
| Power range | 0.05 to 50+ kW per motor | 0.10 to 5.0 kW per pump |
| Motor size | ~13 to 200+ mm stator OD | Built on the same slotless BLDC platform |
| Voltage | 12 to 800 V DC bus, hybrid HV architectures supported | 12 to 800 V DC bus, AC configurations available |
| Signature | Slotless architecture for low acoustic and EM signature | Seal-less design removes the primary maritime leak path |
| Roles | Main propulsion, vectored and station-keeping BLDC motors, and winch and actuation drives | Engine, battery, and payload cooling loops; bilge, fuel, and ballast transfer |
Standard configurations within these ranges are sold commercially off the shelf. Parameters reflect current platform capability ranges. Application-specific performance data, including duty cycle and environmental qualification, is available under NDA and co-developed to program requirements.
