Table 31/1: Rated operating conditions for spring-applied multiple-disc brake
Explanations on the technical specifications:
W
(maximum switching work) is the switching work that must not be exceeded during braking operations at
max
max. 1500 rpm. Braking operations at >1500 rpm substantially reduce the maximum permitted switching work
per switching operation. Such operation is only allowed after prior consultation with the manufacturer. The
maximum switching power P
of applications where the number of switching operations per hour is Z>1, Fig. 30/1 or Fig. 30/2 (W
function of the number of switching operations per hour Z) applies. The P
values; they apply to applications where the brake is mounted between the B-face end shield of the motor and
the motor fan or attached to the motor. The specified times apply to the following conditions: DC side brake
switching, operating temperature, rated voltage, and rated air gap. All values are mean values that are subject
to variation. In case of AC side brake switching, the coupling time t

break-in process has been completed (see Table 29/2). Vertical brake operation is only allowed after prior
consultation with the manufacturer.
Note: A current level corresponding to 70% of the rated current is reached if the brake is operated at rated
voltage and at a coil temperature of 130°C.
The required operating conditions specified in Table 31/1 and the information provided in the CLASSIC LINE
specification sheet and offer drawing must be observed during operation of the spring-applied single-disc
brake.
