Siemens SIMOTICS M-1PH8 Configuration Manual

5.2.5.3 Mounted holding brake for SH 180 and SH 225
Properties
For these motors, the brake (manufactured by Stromag) is mounted on the DE end shield. In this
case, the motor shaft is extended using a shrunk-on stub shaft. The torque is transmitted
through a feather key according to DIN 6885/1. The stub shaft can also be axially secured using
a spring washer and a central screw (M20). The holding brake does not have its own bearings.
The output forces are therefore absorbed by the motor bearings. Belt pulleys cannot be mounted
due to space reasons and also due to the high associated cantilever forces. When selecting the
coupling to couple to the motor - brake combination - it should be carefully noted that the shaft
extension diameter is larger than the diameter of the motor shaft extension. REVOLEX bolt-type
couplings 2LF6337 for shaft height 180 and 2LF6338 for shaft height 225 should be preferably
used. Ordering data and dimensions, refer to catalog M 11 or D 81.1.
Note
Radial and axial forces
The speci󹪝cations for the "standard" bearing version apply for the permissible radial and axial
forces.
