What is a brushless DC motor
What is a brushless DC motor brushless DC motor. The square wave self-controlled permanent magnet synchronous motor is used to replace the carbon brush commutator with Hall sensor, and the neodymium iron boron is used as the permanent magnet material of the rotor. The product performance surpasses all the advantages of the traditional DC motor, and at the same time solves the DC brush of the DC motor. The shortcomings of the slip ring, digital control, is the most ideal speed regulating motor. This product has the characteristics of high efficiency, high torque and high precision. At the same time, it has small volume and light weight, and can be made into various volume shapes. It is the most efficient speed-regulating motor of today, compared with the traditional DC brush motor, or has better performance compared with the AC frequency conversion speed regulation; in the traction motor battery car EV industry, in addition to the traditional DC brush motor, in addition to higher In addition to the characteristics of efficiency and higher starting torque, the use of square wave drive allows the lead-acid battery to have time to repair the electrode plate, which can extend the life of the battery and increase the battery capacity by about 1.3 times. The overall efficiency can be doubled. The battery capacity greatly improves the performance of the battery car. Brushless DC motors have been widely used in the military industry in the advanced countries, information industry (IT), office equipment (OA), home appliance industry (HA), DIY hand tools, servo System, electric car, battery car, magnetic cyclone train, etc. After more than ten years of research and development, the company has a production capacity of 75KW and a design capacity of 315KW, which can meet the industrial automation and fluid machinery, energy-saving drive of air-conditioning machinery. Application.
Brushless DC motor has the above three high characteristics, which is very suitable for industrial machinery and air conditioning refrigeration mainframes, fan and water pump, air compressor load for continuous operation in 24 hours; low speed and high torque and high frequency positive and negative are not hot. The characteristics are more suitable for the driving of machine tool working machine and traction motor; its steady speed operation accuracy is higher than that of DC brush motor, and it is higher than the vector control or direct torque control speed closed loop frequency conversion drive, and the performance price ratio is better. It is the best choice for modern speed control drive.
Due to the flexible size and different electrical characteristics of this product, except for the general-purpose G series and the high starting torque M series, the application of each industry is different, so the user must propose the electrical characteristics and mechanical dimensions before ordering.
