SECTION 7 DC ELECTROMAGNETIC BRAKE (CE ONLY)

1 - Electromagnet,
2 - Armature complete with brake linings,
3 - Fan,
4 - Retaining bolt
5 - Central spring,
6 - Special washer,
7 - Set screw,
8 - Self-locking nut,
9 - Sealing ring,
10 - Output cable.

7.1

Design and principle of operation

The DC electromagnetic brake type H consists of 3 main subassemblies:

- electromagnet (1),

- armature complete (2)

- cast iron fan (3).

lectromagnet (1) energised:

The DC voltage from the motor applied via the rectifying circuit

causes the attraction of the armature (2) releasing the brake and thus the fan (3) is free to rotate.

Electromagnet (1) de-energised:

The electromagnet stops to attract the armature (2) and spring

presses the armature with brake linings (2) against the fan and the brake is thus applied.
