42mm 24V BLDC Motor 3 Phase 4000 Rpm With 5mm Round Shaft 25W / 26W
Brushless DC motor itself is the electromechanical energy conversion part, it in addition to the motor armature, permanent magnet excitation two parts, but also with a sensor. The motor itself is the core of brushless DC motor, which not only relates to performance index, noise and vibration, reliability and service life, but also involves manufacturing cost and product cost. By adopting permanent magnetic field, the brushless DC motor can get rid of the traditional design and structure of the general DC motor, which can meet the requirements of various application markets, and develop towards the direction of saving copper and materials, and making it easy.

The development of permanent magnet field is closely related to the application of permanent magnet materials. The application of the third generation of permanent magnet materials promotes the brushless DC motor to the direction of high efficiency, miniaturization and energy saving.
Product Description
Ideal Applications for BLDC Motors
We’ve seen that BLDC motors offer high efficiency and controllability, and that they have a long operating life. They are widely used in devices that run continuously. They have long been used in washing machines, air conditioners, and other consumer electronics; and more recently, they are appearing in fans, where their high efficiency has contributed to a significant reduction in power consumption.
They are also being used to drive vacuum machines. In one case, a change in the control program resulted in a large jump in rotational speed—an example of the superlative controllability offered by these motors.
BLDC motors are also being used to spin hard disc drives, where their durability keeps the drives operating dependably over the long term, while their power efficiency contributes to energy reduction in an area where this is becoming increasingly important.
