PS (Planetary reduction-Segment conductor motor) Starter

2. Armature
Instead of the round-shaped conductor wires used in the conventional starter, the PS (Planetary reduction-Segment conductor motor) starter uses square-shaped conductors. With this type of construction, the square-shaped conductors can achieve the same output as those achieved by winding numerous round-shaped conductor wires, but without the increase in mass. As a result, the output torque is increased, allowing the armature coil to be more compact. Also, because the surface of the square-shaped conductors that are used in the armature coil function as the commutator, the overall length of the PS starter can be further reduced.
