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 battery faster.

A Brushless Motor:

• How it works: It has no physical parts that touch to deliver power. It uses a smart electronic controller to spin the magnet inside.

• The upside:

  • Way more durable: Nothing wears out, so it lasts much longer.

  • More power: Delivers a lot more thrust for its size.

  • Super efficient: Gives you more runtime from your battery.

  • Super reliable: No sparks, which makes it much safer for use in water.

So why are thrusters all brushless?

It's simple: thrusters need to be reliable, powerful, and efficient. Brushed motors just can't hang. They'd wear out too fast, overheat, and drain your battery. For a professional-grade tool, brushless is the only way to go.
