One of the issues we face, applying our systems submerged in product, is leakage. Specifically: shaft seal security.
We developed a Free Flooded Motor Design.
The rotor and stator are both fully encapsulated, such that shaft seals are no longer required.
One of the issues in the past were the Hal sensors. These stop working when submerged.
Hal sensors are magnetic sensors, measuring the motors rotations. This in turn is needed to optionally control the motors.
These are now replaced with inductive sensors integrated in the stator package.
The positive effects are:
Rotational control is integrated and superimposed over the motor power. No more weak Hall signals, requiring (3) separate conductors.
No shaft seals means less rotor friction resulting in higher efficiency
Less maintenance to worry about.
Smaller motor footprint.
Higher torque.
Lower cost (In house technology and all made in the USA)
Implementing now
Re- evaluating our robotic systems we continued to work on integrating multiple functions through multiplexing and superimposing. (TP's: Transmission Protocols)
Similar to a BUS system.
No more multiple submerged modules. We have a single electronic control module on the robot.
Short, screened jumper cables connect to all the modules: 2 motor modules; the 8* transducer UT module; (*This can be Customized); Imaging Sonar module; Navigation module; 2 LED Lights; 2 HD Camera Modules.
For bottom (sludge) profiling and Tank bottom leveling we have an optional module that can be integrated.
