Small Brushless DC Motors

Controlled commutation instead of brushes and commutators, longer lifespan than brushed motors because they don’t have any physical contacts that can wear out over time, typically smaller and more efficient, smoother operation and less maintenance.

Know More About Brushless DC Motors


A brushless DC (BLDC) motor is an electrically commutated DC motor which means that the windings on the rotor are excited by the magnets on the stator. This is in contrast to a brushed DC motor where the armature windings are excited by the commutator brushes.

BLDC motors are typically more efficient than brushed DC motors because there are no brushes to cause friction and wear. They also typically have a longer lifespan since there are no brushes to replace. BLDC motors are often used in applications where high efficiency and long lifespan are important, such as in electric vehicles. Brushless DC motors need to drive by the controllers and drivers.

These motors are readily available and can be sent directly from NFP-Motor to the customer. This eliminates the need for intermediaries or additional handling, ensuring a faster and more efficient delivery process. Customers can easily place their orders and have the motors shipped directly to their desired location(5-7days), saving time and effort. Stock motors are a convenient option for various applications and industries, offering reliable performance and easy installation.

Pre-Production BLDC Motors


The following small BLDC driving motors are typically tailored for corporate customers and undergo a longer production cycle, usually spanning 2-3 weeks. This extended timeline allows for meticulous attention to detail and ensures that the final product meets the highest standards of quality and performance.

During this phase, manufacturers focus on refining the design, optimizing production processes, and conducting rigorous testing to deliver a reliable and top-performing product. The emphasis on quality control throughout the production cycle ensures that any potential issues are identified and resolved before the product reaches the market. These pre-production products are specifically crafted to meet the unique requirements of corporate customers, who often demand exceptional performance and reliability. By investing time and resources into the pre-production phase, manufacturers can deliver products that exceed expectations and provide long-lasting value to their corporate clientele.

A small brushless DC (BLDC) motor is a type of DC motor that uses electronic commutation instead of brushes for commutation purposes. This results in a more efficient motor with reduced electromagnetic interference (EMI). BLDC motors are often used in applications where space is limited, such as in portable electronics.

BLDC motors are typically more expensive than brushed DC motors due to the additional electronics required for commutation. However, the increased efficiency and reduced EMI of BLDC motors can offset the additional cost in many applications.

The electronic commutation of BLDC motors is controlled by a controller, which typically contains a microcontroller and a driver circuit. The controller takes input signals from sensors, such as Hall effect sensors, to determine the position of the motor shaft. The controller then uses this information to generate the appropriate drive signals for the motor coils.

BLDC motors are typically driven by a three-phase AC voltage. The three phases are offset by 120 degrees, which creates a rotating magnetic field. This rotating field interacts with the permanent magnets in the motor to create torque.

How To Control A Small Brushless DC Motors?

1. Determine the voltage and current requirements of the brushless DC motor.
2. Choose a suitable motor controller for the motor.
3. Connect the motor to the motor controller.
4. Connect the power supply to the motor controller.
5. Set the motor controller parameters such as the speed, direction, and current limit.
6. Connect the motor controller to the control system.
7. Use the control system to send commands to the motor controller.
8. Monitor the motor performance and adjust the motor controller parameters as needed.
9. Disconnect the motor from the motor controller when finished.
