The range of brushless DC motor applications is one of the widest today, mostly owing to the device’s remarkable performance and high efficiency. Learn about these uses of the BLDC motor in this section. Among the topics I will be covering are brushless DC motor use in the automobiles, industrial machines and systems, home appliances, consumer electronics, and more. This will help you understand the need for this type of motor in your sector.
Common Brushless DC Motor Applications
The many brushless DC motor benefits make using the motor in a broad range of applications an advantage. These include speeds control, high rpm, high torque, and silent operation. In a nutshell, the motor is one of the most used. Based on these benefits, the application of brushless DC motors can be divided into the following.
Single Speed Applications
BLDC motors provide a flat speed operation. That means the motor maintains speed even when the load varies. These motors are, therefore, suitable for use where the load varies but the speed should not. The flat speed curve of BL motors results from its construction and electronic commutation.
Variable Speed Applications
Brushless DC motor use does not only fit single speed applications. The motor also suits situations where the rpm should vary. Induction motors would be a good choice. However, they would need they would require an external controller which would make the set up too costly. A brushed motor would also fit such situations, but with additional maintenance costs.
Low Noise Applications
BLDC motors are low-noise machines and the best for applications where systems or appliances must operate silently. These include electronic appliances and facilities such as health clinics. Most silent BL motors employ a noise reduction strategy consisting of field-oriented control systems.
Precision Controlled Systems
In some applications, the precise control of movement is required. The working of brushless DC motor parts and electronic control allow usage in such situations. These include robotics, RC vehicles, and more. In all these applications, one thing sands out; precision and controllability.
What are Brushless DC Motors Used for? Specific examples
Having discussed the general brushless DC motor applications, we can now go deeper and take a look at the specific use of the device in appliances and systems. Below are popular areas where the motor fits better than the brushed type as well as the reasons for its preference.
Brushless DC Motor in Car Parts
One of the sectors where the BLDC motor is becoming increasingly popular is the automotive industry. The motor is being used in major vehicle parts such as fans, window elevators, and HVAC motors. When used in these components, BLDC motors perform exceptionally well, and for a long time due to their higher durability.
Brushless DC Motor for Fan
The fans for cooling and heating appliances commonly use brushless motors. The electronic control of these motors allows manufacturers to include features such as speed variation, programmable operation, and remote communication. BL motors are also quiet devices, which makes them suitable for use in fans where noise is unwanted.
Brushless DC Motor for Robot
With the advancement of robot technology, BLDC motors have become the most preferred type of drive and holding device. There are many reasons for their use, such as efficiency, low-heat operation, and compact construction. But the most important advantage for the application is the precise control that brushless motors are capable of, which helps produce accurate robotic systems and devices.
Brushless DC Motor for Electric Bike
E-bikes are a popular with many people. In an e-bike, a BLDC motor is usually affixed to the wheel hub. The rotor then forms part of the wheel, rotating along with it. In turn, the stator is typically built into the wheel hub. The brushless DC motor commutation that requires no physical brushes is one of the reasons for its suitability. The high torque too and efficiency, which are necessary to propel the bike.
Brushless DC Motor for Drone
One of the most popular brushless DC motor applications is in the making of drones. A drone uses several rotors, each with own electronic circuit. These must be controlled separately to achieve ascent, decent, and direction change. BL motors allow that with ease. A brushless DC motor for drone must also be lightweight and small enough to avoid introducing too much weight. Compactness is one of the BL motor characteristics.
Brushless DC Motor for Lathe
BL motors are common in power tools such as lathes, where they offer the advantage of low weight and high efficiency. They also generate higher levels of torque in high rpm, a major requirement for lathe operation. Most of the time, a brushless DC motor for lathe is a heavy-duty type capable of both high torque and speed.
Brushless DC Motor for Golf Cart
Brushless motors are popularly used to propel small vehicles such as golf carts. There are many reasons for the application. One of the most important is the motor’s high efficiency, which makes it save energy better than a conventional brushed motor. The reduced maintenance requirements and high torque-to-weight ratio also makes a BL motor suit golf carts.
Brushless DC Motor in Computers
Brushless motors are also commonly used in computers. Examples include use in hard disks, CD-ROM drives, and the cooling fans of computers. One of the advantages of BLDC motors when used in a computer is low noise. The motor is also a zero-maintenance device, which means a user will not need to change parts to keep the motor going. Other benefits include the compact size and longer life than the brushed types.
The BLDC motor is one of the most common types of DC motor day. As we have seen, the benefits it offers range from low noise, high efficiency, and durability. Many brushless DC motor applications also require compact yet high torque devices, and the motor fits that perfectly. In the next and last part, I show you how to select the best motor for your specific application or project.
