I have an engineering background however I am new to motors. I am looking to understand what the options exist for maximizing the top speed a motor can produce (say for an RC vehicle) without simply using the "brute force" option of "buy a bigger, heavier, more expensive motor with a higher number of maximum RPMs". Because after a point there is a step function in terms of size and cost that make selection impractical depending on application.
Seems like there is plenty of motorization in the world, so this has to be a solved problem--I just need some pointers to pursue learning more. Specifically: what options exist to maximize motor output for speed? What are the advantages and disadvantages of each?
All useful help appreciated--thank you!! Happy to clarify if anything is not clear.
