Buyer's Guide: Understanding Thruster Direction (CW/CCW, Positive/Reverse Thrust)

Navigating thruster specifications can be confusing. This guide will help you understand the key concepts and make the right purchase decision for your project. 1. The Quick Summary: Key Takeaways Focus on Function: What matters most is the functional result – Positive Thrust (main forward direction) and Reverse Thrust (backward direction). CW/CCW are Means to an End: Clockwise (CW) and Counter-Clockwise (CCW) describe the mechanical rotation. Alone, they do not define forward or backward movement. The Propeller is the Key: The direction of thrust is determined by the combination of the rotation direction (CW/CCW) and the propeller's design (e.g., a "right-handed" or...

Why all thruster motors brushless? Brushed or brushless?

Why are all thruster motors brushless? In short, brushless motors are tougher, more powerful, and way more efficient. They're the clear winner for something that needs to run hard and reliably, like an underwater thruster. Brushless vs. Brushed: What's the difference? Think about how the motor works on the inside: A Brushed Motor: How it works: It has these little carbon "brushes" that physically rub against a spinning part to deliver power. The downside: This rubbing causes friction, wear, and sparks. Over time, the brushes wear out and the motor gets weaker. They're less efficient, which kills your...

What is PWM ?

When it comes to remote-controlled (RC) vehicles, drones, and robotics, one term you’ll frequently encounter is PWM—short for Pulse Width Modulation. Understanding PWM is essential for fine-tuning your RC setup, especially when pairing it with high-performance components like the ones available at HobbyWater.

How to choose battery?

Choosing the Right Battery for Your Underwater Thruster: A Simple Guide If you're gearing up for an underwater adventure with an underwater thruster, selecting the right battery is crucial for optimal performance and safety. Here’s a straightforward guide to help you make the best choice. 1. Match Battery Voltage Why It Matters: Your underwater thruster has a specific voltage requirement. For instance, if it’s designed to run on 12V, you need a 12V battery. Using a battery with the wrong voltage can lead to poor performance or even damage your...
