As a high-efficiency mechanical equipment, DC brushless motor has brought great convenience to mechanical production and electromechanical operation. It is widely used in many fields and plays an important role.
1. First of all, the brushless DC motor has more abundant effects than the ordinary motor. It not only has the operating efficiency of the ordinary motor, but also on this basis, it also improves the failure function of the ordinary motor and has a good starting effect. In addition, it has the characteristics of long life and high reliability. In addition, it usually uses permanent magnets as the rotor without excitation losses; the armature winding that generates heat is usually installed on the outer stator, so that the thermal resistance is small and the heat is easy to dissipate. Therefore, the brushless DC motor has no commutation sparks, no radio interference, and easy maintenance.
2. On the other hand, when performing specific production operations, DC brushless motors also have obvious advantages in terms of operating efficiency. It also speeds up the power supply process on the basis of rapid operation, providing a continuous source of power for the entire operation process. Its rotational speed is not limited by mechanical commutation, such as air bearings or magnetic bearings, which can run at speeds of up to hundreds of thousands of revolutions per minute. Because the DC brushless motor has the above-mentioned series of advantages, it is widely used.
