[JyeSmith]’s ESC tester is capable of just that ... you can always build your own brushless motor. Video after the break.

A brushless motor requires a motor controller, and for most of us, this means cheap Electronic Speed Controllers (ESC) from a warehouse in China. [Ben] had a better idea: build his own ESC.

Sensorless brushless motors offer a compelling combination of efficiency, durability, and cost savings, making them ...

Sensorless motors shine in higher-speed domains where efficiency is maximized. In high throttle settings, ESC does fast power ...

The choice of motor is important in robotics, as it influences how well the robot will perform in terms of efficiency and ...
