Overview
This Surpass Hobby motor is a 540-size brushed DC motor with a 23-turn winding. The 540 can is the standard motor size for 1:10 scale RC cars, so it also fits most hobby robot chassis built around that format.
The motor is rebuildable: the rotor can be removed, and the brushes and springs can be replaced when they wear. Solder tabs on the end bell take the power leads.
