Brushless dc motor controller is composed of main body of the motor and drive, is a typical mechatronics product. With the development of industrial level, the brushless dc motor controller with high efficiency, reliability, is becoming more and more widely applied in industry. Small make up today will give you introduce brushless dc motor controller with carbon brush motor controller, the main difference between friends will quickly learn! : 1, scope of application: brushless motor controller is often used in the equipment of high speed is higher in the control requirements, such as model aircraft precision instrument strict rotation speed of the motor controller speed control to achieve high equipment business. 碳刷电机控制器:通常动力设备使用的都是有刷电机控制器,另外串激电机控制器的转速也能达到很高但是由于碳刷的磨损使用寿命不如无刷电机控制器。 2 、使用寿命:无刷电机控制器:通常使用寿命在几万小时这个数量级但是由于轴承的不同无刷电机控制器使用寿命也有很大不同。 碳刷电机控制器:通常有刷电机控制器的连续工作寿命在几百到1千多个小时到达使用极限就需要更换碳刷不然很容易造成轴承的磨损。 3, use effect: brushless motor controller, are usually digital frequency conversion control, controllability is strong, from a few rotations per minute (RPM), to the tens of thousands of revolutions per minute can be very easy to implement. Carbon brush motor controller: the brushless motor controller usually starts working speed constant, speed is not very easy, series motor controller can achieve 20000 revolutions per second, but life is short. 4, energy-saving aspects: relatively, brushless motor controller adopts frequency conversion control than series motor controller and energy saving will be many, the most typical is the frequency conversion air conditioning and refrigerator. 5, maintenance aspects in the future, need to replace carbon brush carbon brush motor controller, if change will cause the damage to the motor controller, and brushless motor controller, a long service life and are usually brush motor controller more than 10 times, but is broken just need to replace the motor controller, but basic don't need daily maintenance. 6, noise has nothing to do with whether a brush motor controller, basically be to see bearing and click on the matching of the internal components. A brush motor controller is refers to the motor controller is a dc input, controls the size of the controller only give it its current can speed; The brushless motor controller is a three-phase ac motor controller, controller to convert the dc to three-phase alternating current (ac), and according to the motor controller in the hall element sensor to commutation motor controller to normal operation. Direct, brushless motor controller than to have brush motor controller started long service life, strong power, but higher than brush controller cost controller.
