Coreless motors, also known as hollow cup motor, are a specialized type of DC motor that offer several advantages over traditional brushed motors. These motors are characterized by their unique design, which eliminates the iron core in the rotor, resulting in a lightweight, high-efficiency, and low-inertia motor. This makes them ideal for applications requiring rapid acceleration, precise control, and compact size. Below, we will explore some of the common models and series of coreless motors available in the market.
