Brushless dc motor energy saving, long life, low noise, small and lightweight.
despite the brush motor has high efficiency, miniaturization, low power drive, the cost of production, the advantages, but at the same time there is also a brush friction noise, spark, electronic jamming, and shorten the service life of the motor caused by brush wear, etc. In order to solve these problems, the brushless dc motor arises at the historic moment.
brushless dc motor stator coil circuit USES magnetic force to drive the permanent magnet rotor, by sensor and electronic circuit used to take advantage of the brushless dc motor with brush and commutator implementation of current switch. Thanks to the development of the peripheral technology such as semiconductor, and brushless dc motor as realizing the function of the motor for the first time in the current voltage is proportional to the speed and torque, this point, has the characteristics of dc motor, while on the structure has the characteristics of ac motor, combines the advantages of both. Brushless dc motor is small, big output power, long life, no spark and interference etc, and has extensive USES.
today, brushless dc motor of the fastest growing first application in the field of motor car market. As the car steering from previous hydraulic type changed to electric, it can realize 3 - save fuelThe effect of 5%, with the energy saving effect of electrification technology increasingly apparent, more and more components are replaced by the motor. Including some higher requirements for control performance, due to the frequent use of must have a long service life of parts also gradually into the dominant position of the motor. In addition, after the automobile power steering motor was used in the air conditioning compressor, even in the future is expected to be in the electric car industry was used as the drive motors. To this end, the limited power into the best kinetic energy, and to develop can be set up in the narrow space of small motor will be the inevitable developing trend of motor in the future. The company will use for a long time accumulation of experience in precision small motor, efforts to become the world's leading automotive motor manufacturing enterprises.
