Electric power steering systems use electric motors to provide the assistance instead of hydraulic systems.
When does a power steering motor not work?
No power steering motor or EPS motor only works when the engine is on and up-to the speed limit of 40kmph as after that the wheels acquire enough inertia and load on front wheels is shifted towards back which is also called squat so the traction of front tires with the road decreases and they can be turned with little amount of force .

What causes power steering to stop when making a turn?
Raising the engine rpm solves this problem. Air pockets in the power steering system interrupt the flow of power steering fluid, momentarily decreasing the pump pressure. An improper system flush or a leak in the lines can introduce air, which causes a temporary blockage or open pocket in the fluid stream.
When was the first power steering system installed on an automobile?
