Description
This 12V Coreless DC Motor features a lightweight, ironless rotor structure that delivers high efficiency, fast response, and stable performance. Compared with traditional iron-core motors, coreless motors offer lower inertia, reduced vibration, and improved speed stability, making them ideal for precision control applications.
With a compact 13mm diameter × 32mm length motor body and reliable output characteristics, this motor is widely used in robotics, medical instruments, handheld devices, drones, and automation systems where smooth and accurate motion is critical.
