4x12mm Coreless Micro Motor 4pcs
Coreless DC motors are a special type of DC motors which, as the name suggests, do not have an iron core in the rotor. Instead, a copper wire winding in a basket form (coil) spins around the outside of a cylindrical magnet. This brings several advantages. Coreless motors can be built much more compactly than traditional DC motors because the mechanism is much more space-efficient. Since there is no iron core, the motor core has much less mass and therefore can significantly accelerate and decelerate faster as well as reach extremely high speeds. The absence of an iron core in the rotor prevents the locking moment caused by magnetic induction; consequently, the rotation is smooth, with minimal noise and vibrations. Of course, there are not just 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 long periods.
