The M200 Motor is a subsea motor designed to run in harsh ocean conditions. It has the same performance as the T200 Thruster, but without a nozzle, making it perfect for use on USVs (like the BlueBoat), AUVs, and in custom projects such as actuators and subsea tooling. It requires a speed controller for operation.
The M200 Motor is essentially the T200 Thruster, but designed to be used in more generic applications. With a propeller, it’s a great propulsor for unmanned surface vessels (USVs) and unmanned underwater vehicles (UUVs), but it can also be used to build subsea tooling, drive a gear-train, or whatever you can imagine!
Check out this subsea rotary cleaning brush that we built as an example application!
Like the our thrusters, the M200 Motor is a flooded three-phase brushless motor. The motor stator is encapsulated and electrically isolated from the water and the magnet rotor is coated and made from stainless steel to make it resistant to seawater corrosion. The motor uses high-performance water-lubricated plastic bushings and is water-cooled as water flows through the motor.
The M200 Motor has a base with four M3 mounting holes to secure it in a wide range of applications. The standard version comes with a 1 meter long cable and the BlueBoat version has a shorter cable with pre-installed cable penetrator and an MT60 connector ready to install on the BlueBoat!
A sensorless brushless electronic speed controller (ESC) like our Basic ESC is required to run the motor in all situations. It’s optimized to run at a voltage of 16V (such as a 4S lithium-ion battery pack), but can run at a range of voltages. Check out the motor user guide for more information and operating instructions!

| ¹ Design life was used to inform testing in an accelerated environment, does not reflect warranty period. ² Note that nominal operation at 12–16 V is recommended for the best balance of power and efficiency, though operation at up to 20 V is allowable. Exceeding 20 V is not within the rating and not recommended. |
