NobbySideways 111 Posted June 12, 2020 As an old man my other hobby is making large model steam engines from brass. I recently made a generator for a stationary engine to run from an old 540 motor but it barely generated anything. I figure I would be better off using a cheap brushless motor and rectifying the output. I've had a look myself but before I pounce (I've never got much cash) whats the cheapest brushless 540 motor on the market at the moment please? It doesn't have to be any good, just have no commutator and three wires hanging out the back of a 540 package.... Sorry to drag this forum into uncool territory... 1 Share this post Link to post Share on other sites
Jonathon Gillham 3245 Posted June 13, 2020 So these are models that have moving parts but no boiler and don't run on steam? That sounds pretty impressive, can you post any pics or video? The cheapest i have seen is from aliexpress or banggood. Brands like GoolRC and Surpass make some really cheap sensorless ones. I assume you need an ESC too? They also do combos cheap. Given brushless make a lot more torque you may be able to use one of the 1/16 scale size too, 2845 or something i think. However, I have no idea so probably shouldn't have mentioned that. Is it alwys running at low speed? Is cogging an issue? No idea if cogging is at low speed, or only for the first few seconds while it sorts itself out Share this post Link to post Share on other sites
NobbySideways 111 Posted June 13, 2020 Ah, sorry, no, these are steam engines, powered by a boiler, I'm just using the motor as a generator. Share this post Link to post Share on other sites

Thats way cooler, you need to post a video of it running...we don't have a steam section, guess since it has a motor it can be in the electronics section?
