Starter car Toyota Camry 2001 - 2006

The compact and lightweight PS (Planetary Gear Motor) starter is used on all models. Since the PS starter has a square conductor armature, its surface is used as a collector, which increases the starter torque and reduces its overall length.

Instead of the field winding used in a conventional starter, the PS starter uses two types of permanent magnets: main magnets and interpole magnets. Main magnets and interpole magnets are efficiently placed to increase magnetic flux and shorten yoke length.

Unlike the conventional starter rotor winding, which uses round wires, the PS starter uses square wires. With such an arrangement, the characteristics that are achieved by using multiple turns of round wires can be obtained without increasing the weight. As a result, the starter torque has been increased and the rotor winding has become more compact.

The surface of the conductors of the square rotor winding is used as a collector, whereby the overall length of the starter PS has been reduced.

Starter components:

1 - anchor;

2 - yoke;

3 - brush;

4 – permanent magnet;

5 - end collector.

Instead of the excitation windings used in a conventional starter, the PS starter has two types of permanent magnets: main magnets and interpole magnets. The main and interpole magnets are installed in the yoke alternately, whereby the magnetic flux generated between the main and interpole magnets is added to the magnetic flux generated by the main magnets. In addition to increasing magnetic flux, this design reduces the overall length of the yoke.
