一、无刷电机与有刷电机在性能上的区别:有刷电机方面
1. The difference of performance between brushless motor and brushless motor: brushless motor
1、 摩擦大,损耗大
1. Great friction and loss
不少朋友在用有刷电机的时分常碰到这个问题,那就是运用电机一段时间以后,需求翻开电机来清算电机的碳刷,费时费力,维护强度不亚于来一次家庭大扫除。
Many friends often encounter this problem when using brush motor. That is, after using the motor for a period of time, they need to turn on the motor to clear the carbon brush of the motor, which is time-consuming and laborious, and the maintenance intensity is no less than a household cleaning.
2、 发热大,寿命短
2. High fever and short life
由于有刷电机的构造缘由,电刷和换向器的接触电阻很大,形成电机整体电阻较大,容易发热,而永磁体是热敏元件,假如温度太高的话,磁钢是会退磁的,使电机性能降落,影响有刷电机的寿命。
Because of the structure reason of brush motor, the contact resistance between brush and commutator is very large, which makes the whole resistance of brush motor larger and easy to heat. Permanent magnet is a thermal element. If the temperature is too high, the magnet will demagnetize, which will reduce the performance of motor and affect the life of brush motor.
3、 效率低,输出功率小
3. Low efficiency and low output power
有刷电机发热问题,很大水平是由于电流做功在电机内部电阻上了,所以电能有很大水平转化为了热能,所以有刷电机的输出功率不大,效率也不高。
Brush motor heating problem, a large level is due to the current work on the internal resistance of the motor, so the electric energy has a large level of conversion into heat energy, so the output power of brush motor is not large, and the efficiency is not high.

2. The difference of performance between brushless motor and brushless motor: brushless motor
1、无电刷、低干扰
1. Brushless, Low Interference
无刷电机去除了电刷,最直接的变化就是没有了有刷电机运转时产生的电火花,这样就极大减少了电火花对遥控无线电设备的干扰。
Brushless motor removes the brush, the most direct change is that there is no spark when the brush motor is running, which greatly reduces the interference of the spark to the remote control radio equipment.

2、噪音低,运转顺畅
2. Low noise and smooth operation
无刷电机没有了电刷,运转时摩擦力大大减小,运转顺畅,噪音会低许多,这个优点关于模型运转稳定性是一个宏大的支持。
Brushless motor has no brush, friction is greatly reduced when running, running smoothly, and noise will be much lower. This advantage is a great support for the stability of the model operation.
3、寿命长,低维护本钱少了电刷
3. Long life, low maintenance cost and less brush
无刷电机的磨损主要是在轴承上了,从机械角度看,无刷电机简直是一种免维护的电机,必要的时分,只 需做一些除尘维护即可。
Brushless motor wear is mainly on bearings, from a mechanical point of view, brushless motor is a maintenance-free motor, when necessary, only need to do some dust removal maintenance.
三、无刷电机与有刷电机在适用范围上的区别
3. The Difference between Brushless Motor and Brushless Motor in Applicable Scope
无刷电机:通常被运用在控制请求比拟高,转速比拟高的设备上,如航模、精细仪器仪表等对电机转速控 制严厉,转速到达很高的设备及比拟高端的设备才被运用。
Brushless motor: Usually used in equipment with high control request and speed, such as aeromodelling, fine instruments and instruments, etc. to control the speed of motor severely, the equipment with high speed and high-end equipment are used.
有刷电机:通常动力设备运用的都是有刷电机,如吹风机、工厂的电动机、家用的抽油烟机等等,另外串 激电机的转速也能到达很高,但是由于碳刷的磨损,运用寿命不如无刷电机。
Brush motor: Usually the power equipment is used with brush motor, such as hair dryer, factory motor, household lampblack machine, etc. In addition, the speed of series motor can reach high, but because of the wear and tear of carbon brush, the service life of brushless motor is not as good as that of brushless motor.
四、无刷电机与有刷电机在运用效果上的区别
4. The difference between brushless motor and brushless motor in operation effect
无刷电机:通常是数字变频控制,可控性强,从每分钟几转,到每分钟几万转都能够很容易完成。
Brushless motor: usually digital frequency conversion control, strong controllability, from a few revolutions per minute to tens of thousands of revolutions per minute can be easily completed.
有刷电机:无刷电机普通启动以后工作转速恒定,调速不是很容易,串激电机也能到达20000转/秒,但是 运用寿命会比拟短。
Brushless motors: Brushless motors work at a constant speed after normal start, speed regulation is not easy, series motor can also reach 20,000 rps, but the service life will be shorter.
五、无刷电机与有刷电机在节能环保方面的区别
5. Differences between Brushless Motor and Brushless Motor in Energy Conservation and Environmental Protection
无刷电机采用变频技术控制的会比串激电机节能很多,最典型的就是变频空调和冰箱。
Brushless motor controlled by frequency conversion technology will save much energy than series motor, the most typical is frequency conversion air conditioning and refrigerators.
六、无刷电机与有刷电机在维修方面的区别
6. Differences between Brushless Motor and Brushless Motor in Maintenance
碳刷电机需求改换碳刷,假如改换不及时会形成电机的损坏,而无刷电机,运用寿命很长,通常是有刷电机的10倍以上,但是坏了就需求改换电机,但日常维护根本不需求。
Carbon brush motor needs to be replaced by carbon brush motor. If it is not replaced in time, it will cause motor damage. Brushless motor has a long service life, usually more than 10 times as long as brush motor. But if it is broken, it needs to be replaced, but daily maintenance is not required at all.
七、无刷电机与有刷电机在噪音方面的区别
7. Differences in Noise between Brushless Motor and Brushless Motor
噪音方面与能否是有刷电机无关,主要是看轴承和点击内部组件的配合状况。
Noise has nothing to do with whether there is a brush motor or not. It mainly depends on the matching condition of bearing and clicking on internal components.
