Coolant system, hydraulic system, fuel system. Various fluids flow within an automobile. The normal way to drive the pumps that circulate these fluids is to split off part of the power of the engine rotation using belts, but for the sake of smaller size and improved fuel economy, the conversion of these systems to electric motor drive is moving forward. The rare earth magnets used in these electric pumping systems require high output together with high resistance to corrosion and high capacity to withstand heat.
