Motor Characterization for Small Running Robots
Summary
The article documents a hands-on motor characterization project testing a selection of small brushless motors for use in compact running robots. It covers a methodology based on measuring line-to-line resistance and back-EMF, defines torque constant and motor constant, and provides detailed observations on each motor’s construction, windings, and performance. The author identifies the Turnigy Multistar Elite 5010 as a strong overall value, with the Turnigy Gimbal motor offering high performance at a higher cost and voltage, and outlines plans for motor control hardware and mechanical integration.
