ZTW Dolphin 100A FOC HV OPTO Waterproof ESC 6-14S for Precision Underwater ROV and AUV Propulsion
FOC Efficiency for Demanding Subsea Missions
The Dolphin 100A FOC HV OPTO combines field-oriented control with full waterproof construction, delivering higher efficiency, smoother thrust, and lower noise than conventional BLDC ESCs — ideal for long-endurance AUVs and precision inspection ROVs.
100A Continuous / 120A Burst with FOC
Rated at 100A sustained and 120A peak on 6-14S LiPo, this ESC uses FOC commutation to minimize motor losses, extending underwater mission time and reducing heat buildup in sealed subsea enclosures where passive cooling is limited.
Parameterless Programming — Rapid Integration
Auto motor parameter identification eliminates manual timing and throttle calibration, allowing OEMs to integrate the ESC into underwater propulsion systems quickly and consistently across production units.
Optocoupler-Isolated Signal Input
HV OPTO galvanic isolation protects control electronics from power-stage noise and ground loops, ensuring reliable communication between the ESC and subsea flight controllers in high-current marine environments.
Full Waterproof Enclosure
Fully sealed waterproof construction operates reliably in humid electronics tubes or direct immersion, protecting against saltwater corrosion and pressure-related condensation during deep dives.
Extended Power Leads for ROV/AUV Layouts
8-gauge power wires (1145mm) and 10-gauge motor wires (145mm) accommodate typical subsea vehicle architectures where the ESC is housed in a dry enclosure and the thruster is remotely mounted.
Shielded Cable & Firmware Upgrade
The 26AWG shielded signal cable (1080mm) rejects electromagnetic interference, while field-upgradable firmware ensures access to the latest FOC algorithm refinements and protocol support.
