17mm Metal Brush DC Motor – 18mm Length, Ultra-Compact, High Speed

The M17-18-MB series is a 17mm diameter metal brush DC motor with an ultra-compact 18mm body length. This miniature motor features a hollow cup (ironless rotor) design, where the coil is self-supporting and does not require an iron core-3. This advanced construction offers significant advantages over conventional iron-core motors, including zero cogging torque, low rotor inertia, and absence of hysteresis and eddy current losses-3. The result is a motor that delivers smooth, efficient operation in a remarkably small package, making it ideal for servo systems, medical devices, robotics, and precision instruments.
