Composed of an electric motor body and a driver, it is a typical mechatronics integrated product that exhibits advantages in the field of speed regulation due to its wide speed regulation, small size, high efficiency, and small steady-state speed error. With the increasing maturity and improvement of technology, brushless motors have developed rapidly in recent years and have been widely used in various fields such as aviation models, medical devices, household appliances, and electric vehicles. Its main characteristics are brushless and low interference; Low noise and smooth operation; Long service life and low maintenance cost; Efficient and energy-saving.
