Description
Blue Trail Engineering’s MTR-2000 underwater motor combines high efficiency and reliability in a compact package, making it perfect for small USVs, AUVs, and a wide variety of motorized subsea applications.
The MTR-2000 is designed to produce high torque at low RPM. When used as a thruster motor, it is able to spin a relatively large-diameter propeller without the need for a gearbox. In USV and AUV applications, this translates to much lower power draw than a traditional shrouded ROV thruster.
As a subsea motor, the MTR-2000’s low speed, high torque, and flexible mounting options make it suitable for applications such as manipulators, drills, wheels, and brushes.
Unlike many other small underwater motors that utilize rubber shaft seals, the MTR-2000 features a magnetic shaft coupling. A ring of magnets mounted to the motor transmits torque to a matching ring of magnets mounted to the shaft. The two sets of magnets are separated by a solid barrier, eliminating any potential for leakage and eliminating the drag inherent in traditional shaft seals.
Shaft loads are supported by dual corrosion-free ceramic ball bearings, producing drastically lower drag and wear than plastic bearings.
The MTR-2000 is rated to 300 meters depth. Its housing is constructed of hard-anodized aluminum components sealed with redundant O-rings. The MTR-2000 can be mounted using the threaded holes on either end of the motor or by clamping to the outer diameter.
An optional propeller adapter allows the user to attach of a wide variety of off-the-shelf propellers (such as the line of efficient, durable, fiber-reinforced propellers from APC Propellers®) or other components such as wheels or brushes. Contact us for assistance in choosing a propeller to maximize performance in your particular application.
A brushless motor controller (not included) should be housed external to the motor and connected with a standard 3-wire connection. The MTR-2000 has a Blue Trail Engineering Cobalt 3-pin bulkhead connector installed on the housing. You will need a regular Cobalt 3-pin cable (NOT a 3-pin Power cable) to connect to the motor.
