往往较为常见的就是减速电机被烧掉,其主要原因是因为没有守时保护和查检,电机出现异常运转而导致温度升高,导致被烧坏。无刷直流电机以电子换向器替代了机械换向器,所以无刷直流电机既具有直流电机杰出的调速功能等特色,又具有沟通电机结构简略、无换向火花、运行牢靠和易于维护等优点。
Often more common is that the deceleration motor is burned, the main reason is that there is no punctual protection and inspection, motor abnormal operation, resulting in temperature rise, resulting in burned out. Brushless DC motor replaces mechanical commutator with electronic commutator, so brushless DC motor not only has the outstanding speed regulation function of DC motor, but also has the advantages of simple structure, no commutation spark, reliable operation and easy maintenance.
无刷直流电机的定子是线圈绕组电枢,转子是永磁体。假如只给电机通以固定的直流电流,则电机只能发生不变的磁场,电机不能滚动起来,只有实时检测电机转子的方位,再依据转子的方位给电机的不同相通以对应的电流,使定子发生方向均匀改变的旋转磁场,电机才能够跟着磁场滚动起来。
The stator of brushless DC motor is armature of coil winding and the rotor is permanent magnet. If only a fixed DC current is applied to the motor, the motor can only produce a constant magnetic field, and the motor can not roll up. Only by real-time detecting the orientation of the motor rotor, and then according to the orientation of the rotor, corresponding current is given to the different interconnections of the motor, so that the direction of the stator changes evenly, the motor can follow. The magnetic field rolls.
电机定子的线圈中心抽头接电机电源 ,各相的端点接功率管,方位传感器导通时使功率管的 G极接 12V,功率管导通,对应的相线圈被通电。因为三个方位传感器跟着转子的滚动,会顺次导通,使得对应的相线圈也顺次通电,从而定子发生的磁场方向也不断地改变,电机转子也跟着滚动起来,这就是无刷直流电机的根本滚动原理——检测转子的方位,顺次给各相通电,使定子发生的磁场的方向连续均匀地改变。
The coil center tap of the motor stator is connected with the motor power supply, and the end of each phase is connected with the power transistor. When the azimuth sensor is turned on, the G pole of the power transistor is connected to 12V. The power transistor is turned on, and the corresponding phase coil is turned on. Because the three azimuth sensors follow the rolling of the rotor and turn on sequentially, so that the corresponding phase coils are also electrified sequentially, so that the direction of the magnetic field occurring in the stator is constantly changing, and the rotor of the motor is also rolling. This is the basic rolling principle of brushless DC motor, which is to detect the orientation of the rotor, and to communicate with each other sequentially. Electricity makes the direction of the magnetic field in the stator change continuously and uniformly.
