Table 31/1: Rated operating conditions for spring-applied multiple-disc brake
Explanations on the technical specifications:
W
max
(maximum switching work) is the switching work that must not be exceeded during braking operations at
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
max
is the switching work W that can be converted by the brake per hour. In case
of applications where the number of switching operations per hour is Z>1, Fig. 30/1 or Fig. 30/2 (W
max
as a
function of the number of switching operations per hour Z) applies. The P
max
and W
max
values are approximate
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
1
is substantially longer. The specified rated
torques M
2
characterise the torque level of the brakes. Depending on the application the brake is used for, the
switching torque M
1
and the transmissible torque M
4
may differ from the specified M
2
values. The switching
torque M
1
depends on the speed (rpm). If the friction surfaces are contaminated with oil or grease the
transmissible torque M
4
and the switching torque M
1
may drop. The technical specifications apply after the
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.
Note!
At different information in the respective offer drawing compared to the information in the operation instructions
the information and explanations in the offer drawing are valid.
Specifications subject to change without notice!
