什么是无刷电机你知道吗?

来源:http://www.jnmcd.com 发布时间:2019-01-21 浏览:
电机是电动车的四大部件之一,它的作用是将电池的电能转换成机械能,驱动电动车车轮旋转,以到达电动车接连骑行的意图。
Electric motor is one of the four components of electric vehicle. Its function is to convert the electric energy of battery into mechanical energy and drive the wheels of electric vehicle to rotate, so as to reach the intent of electric vehicle to ride in succession.
常见的电机品种有:有刷有齿高速轮毂电机、有刷无齿低速轮毂电机、无刷无齿低速轮毂电机、无刷有齿高速轮毂电机、侧挂电机等。
Common motor varieties are: brush toothed high-speed hub motor, brush toothed low-speed hub motor, brushless toothed low-speed hub motor, brushless toothed high-speed hub motor, side-hanging motor, etc.

什么叫有刷电机?
What is a brush motor?
电机作业时,线圈和换向器旋转,磁钢和碳刷不转,线圈电流方向的替换改变是靠随电机转动的换相器和碳刷来完成的。
When the motor works, the coil and commutator rotate, the magnetic steel and carbon brush do not rotate, and the change of coil current direction is accomplished by the commutator and carbon brush rotated with the motor.
有刷电机力气相对无刷电机要大,线较少 ,就一根正负和一根负极线。假如电机回转,只要将两根线的方位对调一下就可以完成,在电动车职业有刷电机分高速有刷电机和低速有刷电机。
The brushless motor has larger force and fewer wires than the brushless motor, so it has a positive and negative pole line. If the motor rotates, it can be accomplished by adjusting the orientation of the two lines. Brush motors in electric vehicles can be divided into high speed brush motors and low speed brush motors.
有刷电机和无刷电机有许多差异,最简洁的辨别方法就是:有刷电机有碳刷,无刷电机没有碳刷。但有刷电机噪音较大,现在有刷电机已基本被淘汰。
There are many differences between brushless motor and brushless motor. The simplest way to distinguish brushless motor from brushless motor is that brushless motor has carbon brush and brushless motor has no carbon brush. But brush motors are noisy, and now brush motors have been basically eliminated.
什么叫无刷电机?
What is a brushless motor?
无刷电机由操控器提供不同电流方向的直流电,来到达电机里面线圈电流方向的替换改变。无刷电机的转子和定子之间没有碳刷和换相器。
The brushless motor is supplied by the controller with DC current in different current directions, which is replaced by the coil current direction in the motor. There is no carbon brush and commutator between the rotor and stator of brushless motor.

无刷电机内部结构
Internal structure of brushless motor
直流电源经过开关电路向电机定子绕组供电,三个方位传感器(俗称霍尔)随时检测到转子所处的方位,并根据转子的方位信号来操控六个开关管的导通和截止,然后自动地操控了哪个绕组通电,及通电方向,然后完成了电子换向。
DC power supply supplies power to motor stator winding through switching circuit. Three azimuth sensors (commonly known as Hall) can detect the orientation of the rotor at any time. According to the orientation signal of the rotor, they can control the turn-on and cut-off of six switches. Then they can automatically control which winding is electrified and the direction of electrification, and then complete the electronic commutation.
无刷无齿电机是现在电动车上应用最为广泛的电机之一,因寿命长,结构相对简略,无噪音等许多优点而被电动车厂家广泛使用。无刷电机有60度角、120度角和180度角之分,操控器角度也应与之匹配。不然新操控器与新电机也不能正常作业。在修理更换时要特别留心角度问题。
Brushless toothless motor is one of the most widely used motors in electric vehicles nowadays. It is widely used by electric vehicle manufacturers because of its long life, relatively simple structure, no noise and many other advantages. Brushless motor has 60 degree angle, 120 degree angle and 180 degree angle, and the angle of the controller should be matched. Otherwise, the new controllers and motors will not work properly. Special attention should be paid to angle when repairing and replacing.
电机主相线
Motor main phase line
无刷无齿电机有八根线,分别是三根主相线粗黄、粗绿、粗蓝以及5根细线。分别为细红线、细黑线、细绿线、细黄线、细蓝线等。可经过数字万用表检测(通电状况检测)或修车宝检测(不通电状况)电机是否存在毛病。
Brushless toothless motor has eight wires, three main phase lines are thick yellow, thick green, thick blue and five thin wires. They are fine red line, fine black line, fine green line, fine yellow line, fine blue line and so on. It can be tested by digital multimeter (power-on condition test) or car repair treasure (power-off condition) whether there is any motor fault.
