20mm Brushed DC Motor – 22mm Length, Ultra-Compact, High Efficiency

The M20-22-MB series is a 20mm diameter brushed DC motor with an ultra-compact 22mm body length. This miniature motor features a hollow cup (ironless rotor) design, where the self-supporting coil eliminates the need for an iron core. This advanced construction offers significant advantages over conventional iron-core motors: zero cogging torque allows smooth operation at any rotational position, low rotor inertia enables rapid acceleration and deceleration, and the absence of iron losses delivers high efficiency
