Application scope of brushless DC motor

Brushless DC motor is composed of a motor body and a driver, and is a typical electromechanical integrated product. The stator winding of the electric motor forms a three-phase star connection, and the rotor of the electric motor is bonded with magnetized permanent magnets. The currently used permanent magnet materials mainly include iron oxide, aluminum nickel cobalt, neodymium iron boron, etc. Based on the linear relationship between the magnetic induction intensity and magnetic field intensity of several materials, neodymium iron boron (Nd-Fe-B) is the most widely used. It has the largest linear relationship range and is known as the third-generation rare earth permanent magnet alloy. In order to detect the polarity of the electric rotor, a position sensor is installed inside the motor. The driver is composed of power electronic devices and integrated circuits, and its function is to control the start, stop, speed change, forward and reverse rotation of the motor, and provide protection and display, etc.

Jinyuan's brushless DC motor is a widely used motor, which has shown remarkable performance in the use of ordinary DC motors, servo motors, and torque motors, as well as in high-tech fields such as advanced electronic equipment, robots, aerospace technology, CNC devices, and medical chemicals. At the same time, its drive circuit design absorbs the stable and precise advantages of today's advanced application specific integrated circuits, playing a huge role in national production and life. In the design, based on the idea of ensuring the good implementation of the driving circuit function and making the entire electronic control circuit structure simple, reliable, and cost-effective, suitable analog components and dedicated motor control integrated circuit chips are selected, and the structure of the electronic circuit is compared, analyzed, and optimized. In addition, brushless motors replace mechanical commutation with electronic commutation, which has the characteristics of no mechanical friction, no wear, no spark, no maintenance, and can achieve better sealing, so they are technically superior to brushed motors.

The brushless DC motors, micro reduction motors, and electric curtain motors produced by Jinyuan Electric are widely used in automotive components, intelligent kitchens and bathrooms, household appliances, medical equipment, communication equipment, industrial equipment, instruments and meters, model aircraft, robots, personal care, security cameras, digital electronics, and more. Especially the DC brushless motors produced by our company have good dynamic and static speed regulation characteristics, as well as advantages such as simple structure, reliable operation, easy control and maintenance. Therefore, they will gradually replace other types of motors in high-performance application fields and occupy a dominant position. The characteristic of phase-locked loop control technology is that it can strictly synchronize the driving motor speed of the equipment with a required reference frequency, thereby achieving high-precision control. Hall components based on the Hall principle have good linear characteristics, high sensitivity, good stability, simple and convenient control, and have been widely used in automatic detection, automatic control, and information technology.
