HYSTERESIS BRAKES AND CLUTCHES
We develop and produce a wide range of magnetic clutches and brakes for the safe and efficient transmission of torque in drive technology for a wide variety of operating conditions. To meet the variety of applications, we build brakes and clutches in a variety of technologies.
CHARACTERISTICS OF THE HYSTERESIS BRAKE
The infinitely variable controllability of the hysteresis brakes is an essential feature that distinguishes the brakes and clutches. This means it can be used in a wide variety of applications.
Why Kern brakes and clutches?
Magnetic powder brakes and clutches
Due to their construction, magnetic powder brakes and clutches offer a high torque with very small dimensions at the same time. The special magnetic powder introduced in the air gap is aligned to chains by the magnetic field of the coil. These chains have different levels of stability depending on the current and cause friction and thus a braking torque.
Permanent magnet hysteresis brakes
Because they are maintenance-free, permanent magnet hysteresis brakes are recommended for use in system parts that are difficult to access. They are characterized by a constant braking torque over the entire speed range. They are therefore the ideal solution for applications that require a constant braking torque.
