PROPULSION / BLUE ROBOTICS

T200 thruster

A compact foundation for ROV movement.

Flooded brushless thruster used in BlueROV configurations and various SORS builds.

THE SYSTEM IN PRACTICE

How it fits
your work.

The T200 uses a brushless motor designed to operate in water. Its flooded construction and component materials distinguish it from a conventional motor housed in a dry enclosure.

Operation requires a compatible electronic speed controller. The number, position and rotation direction of the propellers determine vehicle movement; the thrust of one thruster is not the thrust of the entire configuration.

CONFIGURATIONS, EQUIPMENT AND DATA

A closer look.

A water-flooded motor for marine robotics

T200 is a brushless thruster for ROVs, AUVs and robotic surface vehicles, used in both experimental and professional projects. Its UV-resistant polycarbonate body and epoxy-protected core are designed for the marine environment.

Plastic bearings replace steel ones; other components use aluminium or stainless steel. The design has no air- or oil-filled cavities: water flows through the motor and helps cool it. The propeller and nozzle work together to produce thrust.

Control and equipment

The three motor wires connect to a compatible brushless ESC. Control can use RC radio, microcontrollers and platforms such as Arduino, ArduPilot, Raspberry Pi and BeagleBone. Clockwise and counter-clockwise propellers are available for torque compensation.
