Brushed vs Brushless

In case you’re wondering why brushed vs brushless, here’s a great article that explains the difference and when to use each: https://www.arrow.com/en/research-and-events/articles/powering-a-battlebot

Here’s another: https://battlebots.fandom.com/wiki/Brushless_vs._Brushed_Motors

Brushless motors are almost universally used for weapons motors, for the reasons listed in the article. Brushless motors are used as drive motors for the very large combat bots as well.

Brushless Motor Confusion

But wait! These articles talk about how brushless motors are more efficient than brushed motors! Why do brushed motors dominate smaller bot classes as drive motors?

Some simple reasons:

1. Brushed motors are generally much cheaper.
2. They have more power and torque at low speeds.
3. Controllers only require two wire connections and simpler, less expensive controllers.
4. All of the above means a lower cost and weight penalty.
5. Most importantly, adequate drives with the right gearing and price point are generally much less available in form factors suitable for drive motors in smaller bots.

Note:

Most builders use Silver Sparks for antweight drive motors. The D2822/17 Brushless motor is perfect for weapons motors. It’s used in the Fingertech spinner weapons kits, (horizontal spinner or vertical spinner) either this version or the 4mm shaft version. (Select 4mm shaft option).
