6x14mm Coreless Micro Motor 4pcs.

Coreless DC motors are a special type of DC motors that, as the name suggests, do not have an iron core in the rotor. Instead, a copper wire winding in a basket shape (coil) rotates around the outside of a cylindrical magnet. This brings several advantages. Coreless motors can be much more compact than conventional DC motors because the mechanism is much more space efficient. Since there is no iron core, the motor core has much less mass and can therefore accelerate and decelerate significantly faster and achieve extremely high speeds. The absence of an iron core in the rotor prevents the cogging torque caused by magnetic induction; therefore, the rotation is smooth, with minimal noise and vibrations. Of course, there are not only advantages to coreless motors. Since the motors are built very compactly and can reach extremely high speeds, there is a risk of overheating. Therefore, coreless motors are less suitable for applications where they run continuously for a long time.
