EPS (Electric Power Steering)

EPS is the abbreviation for electric power steering. This is a mechanism that assists steering operations with electrical power. Because power steering until now has been hydraulic, it drained power from the engine even when no steering operation was underway, but by converting to electric, energy consumption when the power steering is not in operation can be cut, which improves the fuel economy. Differing according to the positioning of the electric power steering motor, there are the column type, the rack type, the pinion type, as well as electrical-hydraulic power steering (H-EPS), which retains the hydraulic system and drives the hydraulic pump with an electric motor. In compact cars, many electric power steering systems use ferrite magnets, but in medium- and large-size cars, the use of brushless motors with rare earth magnets is expanding.
