2012年2月15日 · One weakness of this system is the brushes themselves, which can burn out and, even when new, are a source of electrical inefficiency. These motors are referred to as "brushed" motors or, sometimes, "DC" (direct current) motors because they will run if you simply apply a battery to their two input wires. Most flyers these days use "brushless ...

2013年10月2日 · The motors we are dealing with are not three-phase synchronous motors, they are brushless DC motors (BLDC). Three-phase sycnhronous motors are large industrial motors the speed of which is controlled by the frequency of the AC input signal. The speed of our motors, brushed or brushless, is controlled by the voltage level of a DC input.

2019年12月18日 · I've just been looking for some cheap DC high speed motors and I've found a few N30 DC motors. Rated at 3.7v @17000 rpm. Under £1 each with props. Has anyone used these before for flying? I'm wondering if they have enough thrust. Or are there any other 3.7-4.2v DC motors that are lightweight but give decent thrust? Thanks

2006年12月11日 · Hi erfolg, Good question, one hint may be the fact that they are permanent magnet motors (PM) that kinda rules out AC operation, also the term "brushless" refers to a motor that while it has no physical brushes, it still runs as a commutated motor (another hint AC motors don't have Kv ratings, they are frequency dependant), but in this case with a brushless DC …

2008年7月26日 · Basically, I don't know how these motors would run if they varied both potential and frequency, because I don't know what principles were applied in their design. I'll bet at least a few of them would run well on 3 phase AC, but that doesn't mean they're actually 3-phase AC. They're actually brushless motors designed for remote controlled models.

2014年3月12日 · Propeller sizing for electric motors Is there an easy way to determine the propeller range for a motor depending on the motor size?... I think I screwed up - bought 2 motors that are rated at 1800kv - 165W and was planing to use 10*6 electric props which is the size I use the most in my airplanes.

2016年7月22日 · I'm in the planning stages of building a LARGE P-61 Black Widow - around 90" wingspan. I'm starting to do my motor research and would like some suggestions on who's making the higher quality power plants. - and yes, I've searched a bunch of pages here on this forum for this info so please refrain from telling me "Search the forum!", thank you.
