Which motor is suitable for underwater robots

Hello Please help me to find out which motor is suitable for underwater.

BlueRobotics makes parts for underwater robotics, including very affordable underwater thrusters (T100 and T200):

These are BLDC motors and best used with their ESC (motor controller).
For example a T200 motor with ESC: https://www.robotshop.com/en/t200-thruster-basic-esc.html

Thank you sir, but I have query my robot weight is approximately 100 to 150 kg.This T100 - T200 is lift the weight of robot ?

Thank you for clarifying. No, these would not be appropriate for that size of ROV. The T10 / T200 thrusters are best suited for <15Kg ROVs. Unfortunately given the weight you’re looking at, RobotShop does not carry any solutions, nor are there many manufacturers we have found for that size of thruster. Quite a few ROV manufacturers end up manufacturing their own models to integrate into their ROVs. You’ll need to continue the search online.

Okay , Thank you
