In the development of industrial equipment, medical devices, and precision instruments, motor selection is a critical factor that determines product performance.<\/p>\n

In recent years, interest in high-efficiency, long-life Brushless motors has grown, leading to an increasing number of engineers to consider replacing conventional Brushed motors with it. However, determining the specific differences from Brushed motors and assessing applicability to their products requires technical justification and data.<\/p>\n

This article will seek to explain the basic structure and operating principles of Brushless motors to the detailed comparisons with Brushed motors, their advantages and disadvantages for different applications, and selection points for each industrial sector. The technical information necessary has been organized to assist the reader in making a better-informed choice.<\/p>\n\n\n\n

BASIC STRUCTURE AND OPERATING PRINCIPLE OF BRUSHLESS MOTORS<\/h2>\n

\"WHAT<\/p>\n

Unlike conventional Brushed motors, Brushless motors are characterized by a structure that lacks mechanical contact components such as brushes and commutators. Instead, rotation is controlled by switching the direction of the current using electronic circuits. This structure means Brushless motors are not subject to lifespan limitations due to brush wear, enabling long-lasting and highly efficient operation. Below, we explain the basic mechanism of Brushless motors from three perspectives.<\/p>\n
