Larger in what way? A starter can draw more than 300 amps in some cases. However a starter only needs to run for a few seconds and then get plenty of time to cool off. You can burn out a starter if you crank the engine for too long. By contrast a windshield wipers needs to run for hours when you are driving in the rain, and thus needs to be larger to dissipate all the heat. (starters are also typically series wound DC motors which are also smaller, they work great for starters but not for most other motor applications) |
