This product high poly objects. The interior shaft and motor are shown separately. You can place shaft inside motor and rotate it along y-axis. As, you can see, this product is available here in .obj format, but you can request any, I will do it for you. It also contains UV unwrapped textures which may not appear first, but you can set them from the downloaded file, as I have named them correctly. NOTE: I have used Blender version 2.79, using Prinicipled shader. If you want to change, I will do it for you for free.
