The M500 Motor is a high-power subsea motor built for applications that demand more power and efficiency. Like the M200, it’s based on our thruster technology, but without the propeller or nozzle, making it great for a wide range of applications like vehicle propulsion, actuators, subsea tooling, and more. It comes with a pre-installed WetLink Penetrator for easy installation in your system.
The M500 Motor is essentially the T500 Thruster, but designed for a wider range of applications. Without a propeller or nozzle, it’s a flexible building block for things like vehicle propulsion for uncrewed surface vessels (USVs) and uncrewed underwater vehicles (UUVs), subsea tooling, gear-trains, actuators, or whatever else you can imagine.
It’s carefully designed to be more rugged, more powerful, and more efficient than the M200 Motor.
Like our thrusters, the M500 is a three-phase brushless motor leveraging our patented flooded design. Water flows throughout the components, so it’s water-cooled, water-lubricated, and inherently pressure tolerant.
The stator is fully encapsulated and electrically isolated from the water. The rotor features rugged construction with high-performance N52 neodymium magnets protected by a stainless steel abrasion shield, preventing damage from debris or sand. High-performance water-lubricated plastic bearings keep things running smoothly, and the body is made from impact-resistant glass-filled polycarbonate.
The M500 base includes four M4 mounting holes, making it easy to attach to frames, hulls, or just about anything you can imagine.
It comes with a 1.5 m cable with a pre-installed WetLink Penetrator for easy connection to a watertight enclosure or other housing.
The M500 requires an electronic speed controller (ESC) for operation. We recommend the Basic ESC 500, designed for the high-power requirements of the M500 at 24V. The Basic ESC can also be used in lower-power applications, as long as current does not exceed its 30A maximum.
You’ll also need a power source like our lithium-ion batteries and a signal source such as the Thruster Commander, an RC radio receiver, a flight controller like the Navigator, or a microcontroller like an Arduino or Raspberry Pi.

| ¹ Design life was used to define accelerated test conditions and does not represent a warranty period. ² Electrical values are typical; actual units may vary within +/-5%. Measured using the Basic ESC 500. ³ The M500 Thruster has a maximum operating voltage of 24 V, equivalent to a fully charged 6S LiPo or Li-ion battery. Continuous full-throttle operation at 24 V should be limited to 1 minute or less to avoid overheating. |
