We have developed a system of underwater propulsion that requires absolutely no pressure vessels in order to protect the mechanics of a motor. This means lower cost, low maintainance and better performance! Also, no pressure chamber means lower weight than other propulsors on the market, further improving the efficiency.
Motors used are based upon brushless technology and using our control power electronics they work flawlessly and reliably at ANY speed, no matter how low that may be!
In addition to that, along with the propulsor you get our own specially designed power electronics with built-in speed and current closed loop control logic - all you have to do is give the reference of wanted speed (or current) and direction. Electronics will do the rest, your CPU doesn't have to care one bit about the propulsor!
There's a number of advantages of using our propulsors in favor of other products:
User should provide the control power electronics with basic control signals and power connections:
From the user-side of view - No! The interface to the user consists of a power-tap, speed reference, direction selection and an optional shaft-speed signal. It is a bit complicated to manufacture such a propulsor, but let us worry about that :)
