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.
