For many years, a&g is a competent partner in regard to
development, manufacturing and application of hysteresis brakes
and clutches.

Significant features of the hysteresis brakes and clutches from a&g
are their high precision, absolute repeatablitiy and their wearless
character, which is the main advantage of the hysteresis products.
Tensile forces and torques may be regulated continuously.
Corresponding to our devices we provide a reasonably priced
control unit (RHE).
Functional principle
The most important components of hysteresis brakes and clutches
are their rotor and pole structure. This pole structure is composed
of an external body and an excitation coil. These pieces constitute
the static or the actuated part of the brakes and clutches.
The result is a braking and coupling force caused by magnetic
interaction.
Moreover, the pole structure consists of an internal and external
pole structure, which is separated by an air gap.
The rotor constitutes the major difference between hysteresis
brakes and clutches: Regarding hysteresis brakes it is the moving
part, whereas it is the output for hysteresis clutches.
Typical applications
Hysteresis technology is usually employed for winding processes
of yarn, textile, cable, fabrics, paper, plastic layers, etc.
Thus the brakes and clutches of a&g are used in mainly all high
technology applications of winding and stranding industry.
As a result of their high repeatability, their wear- and maintenance
free feature, these devices are also used in test bench technology.
