Efficiency and thermal wise, from a practical standpoint it would be better to use a high turn motor at a higher voltage than to use a low turn motor at a higher amperage (a low turn motor running at a higher amperage will likely get hotter).<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>IN THEORY, the higher the number of turns, greater is the torque that can be generated (and often with less heat).\u00a0 When you are using a brushed motor, a lower turn motor should be equipped with a smaller pinion.
