Relative to the one hundred - year - old has a brush motor, brushless motor cleaner, tiny and light, and is steadily rapid & other; ” to move forward. For they are stable and the increasing popularity, only is the time to summarize obviously too
keep them. just two years ago, brushless motor is far more expensive than a brush motor. But thanks to design the progress of technology and materials, the prices sharply lower. Today, the cost difference between two kinds of motor technology is only 10%. And the most significant change is design researchers began to work closely with industrial application. Traditionally, it is considered to belong to hardcore type has a brush motor applications, & other; ” because a clean working environment is not the most important. But now, due to lower cost barriers, brushless motor was constantly
to new applications. With brush and brushless motor is whether configuration has the most significant difference between common brush -The commutator (刷子, 换向器)。 Over the past century, a commutation of brushless dc motor has been a turn by graphite brush and installed in
