What are the areas of application for brushless motors?

1. Brushless DC motors for automobiles

A car usually includes dozens to hundreds of motors inside. With the rapid development of cars in the direction of energy saving and environmental protection, brushless DC motors have a very good application prospect in cars. In addition to being the core component of a car's drive, motors can also be used for driving air conditioners, windscreen wipers, electric doors, airbags, electric seats and more. At the same time, brushless DC motors are also widely used in the drive of pure electric vehicles and hybrid vehicles.

2. Brushless DC motors for aerospace applications

Typical applications include robotic arm control, gyroscope and servo drives, etc., which generally require good high-speed control accuracy and dynamic response capability, so the corresponding systems are controlled by closed-loop speed feedback, and most use advanced control algorithms.

3. Application in household appliances

The rise of inverter air conditioners has led to a gradual increase in the market share of brushless DC motors in air conditioner drives. In order to save costs and improve the stability of the inverter air conditioning compressor control system, it is advisable to use position sensorless control in the air conditioning compressor. It has been proved that after using position sensorless control, not only the system size is reduced, but also the system efficiency is improved. Disc brushless DC motors (single or double stator structure) are also widely used in the spindle drive of household appliances such as VCDs and DVDs.

At the same time, other household appliances such as hoovers, mixers, hair dryers, video cameras and household fans are gradually adopting brushless DC motors instead of the previously used DC motors, single-phase asynchronous motors and variable voltage and variable frequency (VVVF) driven asynchronous motors.

4. Application in the field of office automation

Computer peripherals and office automation equipment with motors, the vast majority of advanced manufacturing technology and emerging microelectronics technology combined with high-grade precision motors, is a technology-intensive products. Brushless DC motors have been well used in spindle motors for hard disk drives, CD-ROM drives and floppy disk drives, as well as in the drives of office equipment such as digital cameras, laser printers, photocopiers, fax machines, tape recorders, LD disc players and paper shredders.

5. Applications in other industries

Brushless DC motors are currently used in a large proportion of civil and military applications such as robot and robotic arm drives.
