无刷电机与碳刷电机区不同在哪些方面?

来源:http://www.jnmcd.com 发布时间:2019-03-04 浏览:
1.适用范围
1. Scope of application
无刷电机:一般被运用在操控要求比较高,转速比较高的设备上,如航模,精细仪器仪表等对电机转速操控严峻,转速抵达很高的设备商。
Brushless motors: generally used in equipment with high control requirements and high speed, such as aeromodelling, fine instruments and instruments, which have severe speed control and high speed.
碳刷电机:一般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抵达很高,可是因为碳刷的磨损,运用寿数不如无刷电机。
Carbon brush motor: General power equipment uses brush motor, such as hair dryer, factory motor, household lampblack machine, etc. In addition, the speed of series motor can reach a high level, 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.
2.运用寿数
2. Use life span
无刷电机:一般运用寿数在几万小时这个数量级,可是因为轴承的不同无刷电机运用寿数也有很大不同。
Brushless motor: Usually the service life of brushless motor is in the order of tens of thousands of hours, but because of the different bearings, the service life of brushless motor is also very different.
碳刷电机:一般有刷电机的接连作业寿数在几百到1千多个小时,抵达运用极限就需求替换碳刷,不然很简单构成轴承的磨损。
Carbon brush motors: Generally, the connecting operation life of brush motors is from hundreds to more than 1000 hours. When the limit of application is reached, it is necessary to replace the carbon brush, otherwise it will simply constitute the wear and tear of bearings.

3.运用效果
3. Application effect
无刷电机:一般是数字变频操控,可控性强,从每分钟几转,到每分钟几万转都可以很简单完成。
Brushless motor: generally digital frequency conversion control, strong controllability, from a few revolutions per minute to tens of thousands of revolutions per minute can be very simple to complete.
碳刷电机:无刷电机一般发起以后作业转速安稳,调速不是很简单,串激电机也能抵达20000转/秒,可是运用寿数会比较短。
Carbon brush motor: Brushless motor generally starts after the operation speed is stable, speed regulation is not very simple, series motor can also reach 20,000 rps, but the use of life will be relatively short.
4.节能方面:相对而言,无刷电机选用变频技术操控的会比串激电机节能很多,最典型的就是变频空调和冰箱。
4. Energy saving: Relatively speaking, the brushless motor operated by frequency conversion technology will save much more energy than the series excitation motor, the most typical of which is the frequency conversion air conditioning and refrigerator.
5.日后修理方面,碳刷电机需求替换碳刷,如果替换不及时会构成电机的损坏,而无刷电机,运用寿数很长,一般是有刷电机的10倍以上,可是坏了就需求替换电机,但日常维护根本不需求。
5. In future repair, carbon brush motor needs to replace carbon brush. 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 replace motor, but daily maintenance is not required at all.
6.噪音方面与是否是有刷电机无关,主要是看轴承和点击内部组件的合作状况。
6. Noise has nothing to do with whether there is a brush motor or not. It mainly depends on the cooperation between bearing and clicking on internal components.
7.有刷电机是指电机是直流电输入,操控它的操控器只给它供应大小电流就可以调速了;而无刷电机其实就是个三相沟通电机,靠操控器把直流电转换成三相沟通电,并依据电机里的传感器霍尔元件进行换相使电机正常工作。直接来说,无刷电机比有刷电机寿数长、起步有劲省电,可是操控器却比有刷操控器本钱高。
7. Brushless motor refers to the DC input of the motor, and the controller that controls it can only supply it with large and small currents to adjust the speed. Brushless motor is actually a three-phase communication motor, which converts DC into three-phase communication electricity by the controller, and commutates the motor according to the sensor Hall element in the motor to make it work normally. Direct speaking, brushless motors have a longer life than brushless motors and a strong start to save electricity, but the cost of the controller is higher than that of brushless motors.
