Do electric motors use less power when at lower rpm?

I ask this because most electric cars don't have multi gear transmissions. I feel like it would make sense that less rotations would use less power than if it was at 6,000 rpm. I guess it is a pretty straight forward answer but i couldn't find any info on it on the internet or on this forum. Any Info would be greatly appreciated as I am starting to do research on building an electric for my wife. Thanks!!!
