Electronic (Electric) Power Steering (EPS)

By magnifying driving wheel movement, electric power steering (EPS) systems make steering easier. Additional torque is provided by brushless DC motors due to their compact size and relatively low system cost, with increasing safety requirements driving the introduction of dual-redundancy systems. Brushless DC motors also provide improved performance, longer lifetimes, reduced noise, increased reliability and ease of installation.
