-M electromagnetic safety brakes
Type 891._1.0
Standard with friction disk
Type 891._14.1
Enclosed design (IP 65)
with flange plate
Type 891._14.
Tacho attachment design
with flange plate
1) Braking torque tolerance = +30 %/-10 %, for other adjustments see
Table 3, page 7 and Type key page 3.
1.1) Minimum bore not permitted for braking torque adjustment = 125 %.
1.2) Braking torque tolerance = +40 %/-20 % (slight grinding necessary).
2) The respective maximum bores are to be seen in relation to the
corresponding keyways and their tolerances acc. Table 2 page 7.
3) Brake operation from 700 Nm on only possible with overexcitation.
4) Hub facing side (both sides) 3 mm deep, Ø 97 recessed.
5) Brake operation only possible with overexcitation.
6) The IP65 design is equipped with a sealing cover on size 1000:
L = 149 mm, L
4
= 170 mm.
7) Projection screw plugs (emergency hand release): 8,5 mm
8) For flange plate securement: additional 2 x M12 screws (dimensions
available on request).
Standard voltages 24; 104; 180; 207 V.
We reserve the right to make dimensional and constructional alterations.
Permitted voltage tolerance acc. DIN IEC 60038 (±10 %).
* Outer diameter friction disk: free size; outer diameter flange plate: -0,2
Missing dimensions are identical with Type 891.011.0 see page 4.
