Covers 2, 6 and housing 3 of the stator are pulled together with two pins. The armature shaft 23 rotates in two ceramic-metal inserts installed in the cover 2 and support 21. Four permanent magnets 22 are fixed in the stator housing.
The rotation from the armature shaft 23 is transmitted to the drive shaft 14 through a planetary gear, which consists of a central gear 20, three planetary gears 10, a carrier 19 and an internal gear 18. Planetary gears rotate on needle bearings.
The starter connection diagram is shown in fig. 7-16. When the starter is turned on, the voltage from the battery through the ignition switch and the power contacts of the additional starter relay is supplied to both windings of the starter traction relay (retractor II and retainer I). After closing the contacts of the traction relay, the retracting winding is turned off.
