Brush DC Motors
Brush DC Motors — low friction, low starting voltage, high power density
Overview
Brush DC motors deliver high power density in a small package, with low friction, low starting voltage, minimal iron loss, and excellent speed-torque performance. These ultra-compact motors are designed for portable and small devices, and coreless motor technology gives them low rotor inertia and high motional efficiency for a compact, precise, energy-efficient solution.
