a, brushless motor controller and a motor controller on the performance of the difference between the two: a motor controller in terms of the 1, friction is big, big loss a lot of friends in with a brush motor controller often encounter this problem, that is to use the motor controller after a period of time, need to open the motor controller to clean up the carbon brush of the controller, time-consuming, laborious maintenance strength as a household cleaning. 2, fever, life is short due to the motor controller structure reason, the brush and commutator of the contact resistance is very big, cause the motor controller integral resistance is bigger, easy to heat, and permanent magnet is a thermal sensor, if temperature is too high, will be demagnetization magnetic steel, the motor controller performance degradation, affect the service life of a brush motor controller. 3, the efficiency is low, the output power of small motor controller the heating problems, largely because the current work on the internal resistance of the motor controller, so electricity have much transformed to heat energy, so there are motor power output of the controller is not big, the efficiency is not high also. Brushless motor controller and a motor controller on the performance of the difference between the two: brushless motor controller in 1, brushless, low interference in addition to the brushless motor controller brush, the most immediate change is not a brush motor controller during edm operation, thus greatly reduce the electric spark interference of remote radio equipment. 2, low noise, smooth operation without brush, brushless motor controller greatly reduce friction during operation, smooth operation, low noise will be many, the advantages of model running stability is a huge support. 3, long life, low maintenance cost less brush brushless motor controller of wear is mainly on the bearing, from the mechanical point of view, brushless motor controller is almost a maintenance-free motor controller, if necessary, you just need to do some cleaning maintenance. Three, brushless motor controller and a motor controller in the scope of the difference between the brushless motor controller: usually used in the control request is higher, higher speed of devices, such as model aircraft, precision instruments and meters for motor controller speed control strictly, spins at very high equipment and high-end equipment are to be used. A motor controller: the power equipment used are usually brush motor controller, such as hair dryer, electric motor factory, household smoke lampblack machine, etc. , series motor controller speed also can achieve very high, but because of the carbon brush wear, the service life of the brushless motor controller. Four, brushless motor controller with a motor controller is difference in the use effect of the brushless motor controller: usually digital frequency conversion control, strong controllability, from a few rotations per minute (RPM), to the tens of thousands of revolutions per minute can be very easy to implement. Have a motor controller: the brushless motor controller general after starting work speed constant, speed is not very easy, series motor controller can achieve 20000 revolutions per second, but life is short. Five, the brushless motor controller and motor controller in the field of energy conservation and environmental protection is the difference between the brushless motor controller adopts frequency conversion control than series motor controller and energy saving a lot of, the most typical is the frequency conversion air conditioning and refrigerator. Six, brushless motor controller and motor controller in the maintenance of the difference 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. Seven, brushless motor controller and a motor controller in the aspect of noise the difference between the two noises have nothing to do with whether a brush motor controller, basically be to see bearing and click on the matching of the internal components.
