Precision in movement
The ZF Friedrichshafen division Special
Driveline Technology is able to offer you a
wide range of machine drives, brakes and
clutches for applications in engineering as
well as customer specif ic drive solutions.
Our development and production activities are
focused on servo-assisted drives for automa-
tion engineering, two-speed drive gearboxes
for machine tools as well as customer-speci-
f ic drives, such as for printing machines,
robot applications and elevator gearboxes.
Our innovative standard products range from
low backlash servogearboxes (ZF-Servoplan),
and robust two-speed gearboxes (ZF-
Duoplan) to hysteresis clutches and brakes
for non-contact web control (ZF-Tiratron).
ZF Hys te res i s p roduc t s
ZF Hysteresis components
are brakes, clutches and ERM
electronic control unit.
ZF Tiratron, i.e. the combination
of the brake with the electronic
control unit or the clutch with
the electronic control unit, enables
the exact control of tensile forces
as well as a def ined setting of a
torque.
Exemplary operation
The ZF hysteresis technology can
be used and applied wherever pro-
ducts, such as paper, wire etc., are
processed by winding. Loads can
be simulated with Tiratron on test
benches or in ergometers.
Non-contact torque transmission
The non-contact torque transmis-
sion via the airgap of the mecha-
nical componentes brake or
clutches, is continuously variable,
then constant and free of any wear.
Continuously adjustabel torque
The brake torque or the transferable
torque depends only on the current.
It is largely speed-independent and
form zero to maximum speed con-
stantly available.
High slip power in continuous mode,
overload capability
The brakes of the power optimized
series can bear high slip power
continuously. Overloads can be
applied for a short-term period.
The system, consisting of the break
or clutch and the universal usable
control unit, is standardized and can
be used for most of the applications.
Operating principles
The operating principles of hysteresis
brakes and clutches are based on the
magnetic force effect of attracting
poles in synchronous mode and on
continuous magnetic reversal in slip
mode.

Types:
- Torque-optimized series
- Power-optimized series
- Power-optimized series with gearbox
The armature and the brake magnet
are the individual components making
up the ZF hysteresis brake.
ZF Hysteresis brakes are offered
with a nominal torque ranging from
0.05 Nm to 520 Nm, depending on
the size, available as bearing version
with shaft end or non-bearing version
as individual components.
The brakes have a power capacity of
up to 2000 W during continuous ope-
rations and of 4000 W during short-
term operations (interval operations).
They can be used both in the slip
mode range and as a holding brake.
Typical torque-current-diagram
Only the current preset in the magnet
solenoid defines the slip and holding
torque, which can be infinitely adjusted
from zero to the maximum value.
The torque is almost independent from
speed. Major temperature increases
cause a slight reduction of torque.
Slip power
During continuous slip mode, heat
generation caused by slip power
must also be taken into account.
Permissible continuous slip power
limits are included in the selection
tables. Required continuous slip
power is calculated as follows:
Ps = Ts. —— or Ps = F . v
Residual magnetism
Torque ripple occurs as a result of
residual magnetism when the current
is changed to below 50% of the initial
value either abruptly or without tur-
ning the armature/rotor.
A reliable way to avoid torque ripple
is to reduce the current while simul-
taneously turning the armature and
rotor resp. brake solenoid during
approx. 1 turn (relative).
Every following operation cycle
is removing possible residual
magnetism.
Manufacturing and torque tolerances:
When ordering the standard version
according to the catalog, an individual
unit’s torque-current curve as well as
its torque relative to nominal current
may deviate slightly from the publis-
hed data due to production tolerances.
A typical deviation for individual
units would be +/- 10 %.
Upon request, we can offer specially
matched pairs for those applications
requiring lower tolerances.
The actual torque-current curve for a
specif ic unit is exactly reproducible
under the same conditions.

Remarkable features of the permanent magnet (PM) hysteresis brake are its high nominal torque with a compact design.
The brakes permanent magnet excitation makes it independent of any power supply. The torque values can be set and
reproduced easily and in a user-friendly fashion with the 37-times detented setting ring. The tolerance of the nominal tor-
que amounts to +/- 5 %.

Hys te res i s c l u t ches
Rotor, armature and clutch magnet
are the components that make up
the ZF hysteresis clutch.
The nominal torque as offered
ranges from 0.4 Nm to 12 Nm.
The maximum continuous slip
power of the hysteresis clutch
amounts to 500 W.
The ZF hysteresis clutch distin-
guishes itself by a stepless tran-
sition from synchronous to slip
operations.
The magnitude of scattering and
torque tolerances correspond to
the values of the ZF hysteresis
brakes.
As is the case with the brakes,
special series are available on
demand.
Slip power
During continuous slip mode, heat gene-
ration caused by slip power must also be
taken into account.
Permissible continuous slip power limits
are included in the selection tables.
Required continuous slip power is calcula-
ted as follows:
Ps = Ts. —— or Ps = F . v
Residual magnetism
Torque ripple occurs as a result of
residual magnetism when the current
is changed to below 50% of the initial
value either abruptly or without turning
the armature/rotor.
A reliable way to avoid torque ripple is
to reduce the current while simultaneously
turning the armature and rotor resp. brake
solenoid during approx. 1 turn (relative).

The ZF hysteresis electronic control unit
makes it possible to set individual operating
modes for the most diverse applications.
The programming variations allow the
electronic control unit to be used for all
brake and clutch types.

ZF hysteresis clutches and brakes can be controlled in open or closed loop with the ZF electronic control unit,
depending on their application in different operating modes. The electronic components are micro-processor
controlled and have programming, operating and diagnosis interfaces. The ERM electronic control unit has been
set so as to feed the ZF hysteresis clutches and the ZF hysteresis brakes in an optimal way.
26
Open loop control:
- current
- torque
- Ø-sensing
- Ø-calculation
Cloesd loop control:
- PD position control
- PI force control
- PID mixed control
- freely programmable (with
diagnosis device Mobi Dig)
The ERM also offers the following
special functions, depending on the
operating mode:
- Maximum current:
Output of the nominal current,
depending on the size
- Zero current:
the power output is set to zero
- Web-break detector in the operating
mode Ø-calculation
- Compensation of the friction
existing in the system
Open-loop controlled operating
modes with a size codification are
less suitable for the power-optimized
brake series.
Please refer to the ERM operating
manual for further information on
the functions, connections etc.
