Structure
A type of slotless DC motor has a unique construction that distinguishes them from traditional DC motors.
- No Iron Core: Because there is no iron core, it is called an ironless DC motor, in contrast to conventional motors.The weight and inertia of the motor are greatly decreased by this design.
- Winding Configuration: The windings are typically made in a honeycomb or basket pattern, allowing for greater efficiency and smoother operation.
- Permanent Magnets: Coreless brushless DC motors use permanent magnets in the rotor, similar to other brushless motor designs, but with the absence of an iron core, they exhibit less cogging and smoother motion.
Direct Current (D.C.)
- Current Type: Operates on direct current (DC), where charge flows in one direction
- Features of Voltage: DC voltage is steady
- Commutation Method: Brushless and brushed DC motors are the two types of DC motors
- Control Complexity: The control mechanism of DC motors is simpler
- Torque and Speed Characteristics: DC motors have the advantages of high torque at low speeds and fast response time
- Applications: DC motors are the first choice for precision and portable applications
By Types
We provide a full range of custom coreless DC motors including coreless brushless DC motors and coreless brushed DC motors.
Coreless Brushless DC Motor

- With no iron core, its rotor features honeycomb-patterned windings, controlled electronically without brushes.
- It delivers high speed (up to 100,000 RPM) and torque density, used in aerospace, medical devices, and precision robotics.
Coreless Brushed DC Motor
- Operates with an efficiency of 70-80% and a voltage range of 6V to 24V.
- Its coreless rotor design uses patterned windings, eliminating the iron core.
- Brushes switch the current, enabling moderate speed (up to 30,000 RPM) and torque.
- It is commonly used in toys, small appliances, and simple robotics.
By Diameter
The conventional diameters of our coreless dc motors are 7mm, 8mm, and 10 mm, and we can also customize the sizes according to your industry needs.

FAQ
What is a coreless DC motor, and how does it differ from traditional DC motors?
An iron core is not present in the rotor of a coreless DC motor; instead, wire windings are used. Compared to conventional DC motors, this design's reduction in weight and inertia leads to increased efficiency and quicker reaction times.
How does a coreless brushless DC motor operate without brushes, and what are its advantages?
A coreless brushless DC motor uses electronic commutation with sensors to detect the rotor's position and switch current through the windings. It offers higher efficiency, longer lifespan, lower maintenance, and reduced electrical noise.
What are the key differences between a brushed coreless motor and a coreless brushless DC motor?
A brushed coreless motor uses brushes and a commutator, while a brushless coreless DC motor uses electronic commutation. Brushless motors are more reliable and efficient than brushed motors, which are more expensive yet need more maintenance.
What are the usual uses for a 12V coreless motor, and what makes 12V a standard voltage?
12V coreless motors are used in portable devices, robotics, automotive applications, and small appliances due to their availability in battery systems and balanced power efficiency.
What are the benefits of using a coreless micro motor in precision applications?
Coreless micro motors offer high efficiency, low weight, and minimal cogging for smooth, precise motion, crucial for precision applications like medical devices, micro-robotics, and fine instrumentation.
How does the absence of an iron core in a coreless DC motor contribute to its performance?
A coreless DC motor may accelerate and decelerate more quickly because it has less weight and inertia due to the absence of an iron core.Additionally, it increases effectiveness and decreases cogging, leading to smoother and more accurate motion control.
