Electric motors of the Direct current of 4 PB
Electric motors of a direct current of the PB series 4 are intended for work in the automated drives of a direct current with food, both from the generator, and from static converters. Electric motors make with the independent or mixed excitement.
Generators are intended for power supply of various receivers. Generators with the mixed or parallel excitement are intended for work with self - excitation
Structure of a symbol: 4 PB of of the XXX X4
4 — serial number of a series; P — the electrical machine of a direct current; B — closed with natural cooling; — points to existence of the tacho generator (can be or not to be); X — height of an axis of rotation, mm; X — the conditional length of the case on MEK 72 - 1 (A, B, S, L, M); X — the conditional length of the core of an anchor (the 1st; 2 — the second); X4 — climatic modification (UHL, O).
