[0002] A brushless motor, consisting of an electric motor and a driver, is a typical mechatronic product. Brushless motors offer advantages such as small size, light weight, excellent controllability, and simplified control. They also have low environmental requirements and have gained significant application in both industrial and everyday fields, such as aerospace, office automation, and transportation.

[0003] As the manufacturing industry continues to attach importance to product quality, the requirements for motor operating noise are also getting higher and higher. At present, the main problems in motor noise testing are as follows: 1. Current testing is done through manual hearing, which is labor-intensive and requires long working hours, which will affect human hearing; 2. Products need to be tested in a soundproof shielding room, which is expensive to build and occupies a large area; 3. When using manual hearing for testing, quality standards cannot determine data standards, which is prone to the risk of missed detection and false detection; 4. The test logs of unqualified products cannot be traced; 5. Manual hearing testing requires only single testing at a time, which is inefficient.
