brushless motor and a brush, as two major categories of dc motor, has gradually spread to all walks of life. Light industry machinery, packaging machine, conveyor, AGV car, logistics conveyor belt, automated machinery, coffee machine, a dishwasher, etc. , from production to life, everywhere is a dc motor. So how to judge a brush motor or brushless motor?
first, look from the appearance, actually both appearance and there is no difference, even can make it same as can be, but physical carbon brush brushless motor for cancelled, save a lot of space, therefore, under the same working power brushless motor to be smaller than a brush motor on a third.
function, the motor USES is the physical, only need the power supply to the motor, the motor will be according to the rated speed, and brushless motor USES a digital signal to dc after a first drive, give the signal by the driver and electricity to the brushless motor to rotate, brushless motor drive industry generally larger, can only separate, civil level of brushless motors because of its simple function requirements, no programming communication, many are integrated into a small circuit board with the motor internal to save space.
use, has the motor while the more convenient, electricity can be used, but the speed, or the possibility of operating in accordance with established is low, and the physical carbon brush wear in high speed quickly, high noise, easy to produce sparks, can not be used in places that have requirements of safety requirements, physical once wear, carbon brush maintenance difficulties, replace carbon brush is the cost of buying a new one. In 2000 hours to reach maximum life. Need to pick up the brushless motor drives used, more complex, but can be directly through the drive speed, can also be through the communication protocol for remote operation and monitoring, and since there is no physical wear of carbon brush, no spark, low noise, high safety, life is generally more than 5000 hours. Easy maintenance, only need to do on the surface of the dust removal process, without refueling cumbersome steps, such as, basically achieve free maintenance level.
so judgment have brush brushless motor, the most important thing is to look to whether have physical carbon brush, the appearance is difficult to determine, as long as have the drive, it must be a dongguan brushless motor.
