Everything You Need To Know About Coreless Brushless DC Motors

Brushless DC motors are becoming increasingly popular in various industries and applications, and coreless brushless DC motors are no exception. This technological marvel has been shaking up the motor industry with its impressive power-to-weight ratio, low noise levels, and minimal maintenance needs. In this short guide, we will discuss all you need to know about this cutting-edge motor technology.


A coreless brushless DC (BLDC) motor is an electric motor with no iron core in the rotor. Instead, the rotor consists of a cylindrical tube made of a non-magnetic material, such as carbon fiber or aluminum, with a winding of copper wire on the outside. The motor's stator comprises permanent magnets arranged around the rotor, which generate a magnetic field that interacts with the rotor's magnetic field to produce rotation.


Unlike traditional brushless DC motors with a ferromagnetic core in the rotor, coreless BLDC motors have several advantages, including higher efficiency, faster acceleration, and lower weight. The absence of the iron core in the rotor reduces the motor's inertia, which allows it to respond more quickly to changes in load and direction. Moreover, the absence of a core means the motor can operate at higher speeds and generate less heat, resulting in a longer lifespan. These motors are used in the following industries:


Robotics

Coreless brushless DC motors are widely used in robotics, particularly in the joints and limbs of robots. These motors provide precise and fast movements. They are also lightweight, compact, and have a long lifespan, making them suitable for use in robots that need to be agile and durable.


Camera

They are commonly used in camera lenses and focus systems. These motors can be controlled with high precision, allowing for smooth and accurate lens movement. They are also quiet and generate little vibration, which is essential for capturing high-quality images.


Dental and Medical Imaging Equipment

The motors are used in dental drills and medical imaging equipment such as CT and X-ray machines as they provide precision and efficiency.


Dispensing Equipment

In dispensing equipment like pumps and valves, these motors are used to control the flow of liquids and gasses.


Automated Commercial Door Operators

Coreless brushless DC Motors are used in automated commercial door operators, such as sliding doors and swing doors. These motors provide precise and smooth movement of the doors, which is essential for safety and convenience. They also generate little noise, making them suitable for public spaces.
