  • Electric motors have high torque at low RPM

    For anyone scrolling by and curious about this, this is caused by the combination of physical and electrical resistance. In a typical engine, RPM and torque go up together because it requires more force to get to those higher RPMs (IIRC this is called positive correlation). In a circuit, you have to kind of convince the electricity that it would be better off somewhere else (by connecting to a ground, this is due to electrical resistance), so you have to give it a heavy upfront load to get it going which causes a lot of torque due to the physical resistance
