Main 4 Application Scenarios of Brushless DC Motors

In recent years, the small - and - medium - sized motor and micro - special motor industries in China have developed rapidly. Among them, brushless DC motors, with their characteristics of high efficiency and low noise, have gradually replaced brushed motors and become a rising star in industry applications. This is particularly evident on China's leading outsourcing service platforms. It is reported that in motor control tasks, brushless motors account for 78%, almost monopolizing the demand for motor control tasks on the platform. The following, through some cases, analyzes for readers some of the mainstream application scenarios of brushless DC motors today.

Mainstream Application Scenario 1: Brushless DC Motors for Industrial Equipment
Industrial application scenarios have high requirements for the accuracy, efficiency, performance, etc. of equipment. Brushless motors are mostly used in some light - industrial machinery that requires precise speed and position control.

Mainstream Application Scenario 2: Brushless DC Motors for Automobiles and Electric Vehicles
With the development of automobiles towards energy - saving and environmental - protection, high - efficiency permanent - magnet motors including brushless DC motors have a good application prospect in automobiles. Besides being used as the core component for automobile driving, motors can also be used to drive automobile air - conditioners, windshield wipers, airbags for electric vehicle doors, electric seats, etc. The author has learned that the "DC motor control with Hall sensor" case on the Kuabao platform is used to drive the windshield wipers of automobiles.
At present, the starting motor and magneto of electric - start motorcycles are two independent motors. The engine structure is complex, and when the overrunning clutch slips, it will seriously affect the starting characteristics of electric vehicles. The starting motor uses brushes for commutation, and the brushes wear out seriously, requiring frequent maintenance.
The brushless DC starting magneto combines the brushless DC starting motor and the magneto into one, and applies the electronic commutation technology to the starting motor. It eliminates the reduction mechanism and the overrunning clutch, effectively simplifies the engine structure, and improves the operational reliability. It will become the mainstream of future development. The employer in this case has smelled the business opportunity and is determined to develop electric vehicles with brushless DC motors.

Mainstream Application Scenario 3: Brushless DC Motors for Medical Devices
With the development of domestic medical technology and the improvement of people's living standards, the requirements for the practicality and user experience of medical devices are becoming increasingly stringent. For example, due to the needs of surgery, orthopedic medical devices require their power systems to be able to continuously change speed within a wide range to adapt to the requirements of occasions such as slot - milling, drilling, and sawing. The existing driving motors for orthopedic medical devices are single - phase AC - DC series - wound motors and voltage regulators, which produce very loud noise.
Due to the presence of brushes and commutators, it is impossible to disinfect before surgery, which has a certain impact on the surgical effect, and the brushes need to be replaced regularly and the motor needs to be maintained. However, brushless DC motors do not have the above - mentioned hidden dangers. As a driving system, their characteristics of low noise, wide - range speed regulation, small volume, and light weight make them undoubtedly the best choice for medical devices.

Mainstream Application Scenario 4: Brushless DC Motors for Home Appliances
There are compressor motors in air - conditioners and refrigerators. The traditional motors for compressors are usually asynchronous motors, which have low frequency and power factor. The situation has improved after the application of frequency - conversion technology. At the end of 2009, the first bladeless fan of the British company Dyson was born, marking the penetration of brushless DC motors from industrial applications to smart home appliances.
Today, other household appliances such as vacuum cleaners, blenders, hair dryers, cameras, and electric fans are also gradually using brushless DC motors to replace traditional single - phase asynchronous motors. Brushless DC motors can not only overcome some shortcomings of traditional household motors, bringing higher comfort to people's home life, but also reduce energy consumption and better achieve energy sustainability. The following, the author will explain with the "brushless motor controller for ceiling fans" released by Kuabao.

Conclusion: It is not difficult to see that compared with other types of motors, brushless DC motors have more superior performance and have widely penetrated into the fields of daily life and industrial equipment, with a good market prospect. Of course, with the influx of the brushless DC motor boom, more and more enterprises choose to carry out product development through project outsourcing to achieve the maximization of product development benefits at the minimum cost.
