Electromagnetic particle clutch and brake - 0.04 - 25 Nm
These magnetic particle clutches and brakes engage with the application of an electric current to stainless steel magnetic particles in the gap between the output disk/ shaft assembly and the housing. The particles are normally free flowing but when current flows through the stationary coil it creates a magnetic field which causes the particles to form long chains along the magnetic field lines. This links the disk to the housing with a torque that is proportional to the applied input current. Response time is very fast and operation is smooth, reliable and backlash free.
Permanent magnet electromagnetic clutch and brake - 0.01 - 15 Nm
These brakes and clutches use a hysteresis disc between two permanent magnets. When like poles of the two magnets are facing each other they produce maximum magnetic saturation of the hysteresis disc and maximim torque is transmitted to the output shaft. When the opposite poles face each other they produce...
Permanent magnet electromagnetic clutch and brake - 0.01 - 15 Nm
These brakes and clutches use a hysteresis disc between two permanent magnets. When like poles of the two magnets are facing each other they produce maximum magnetic saturation of the hysteresis disc and maximim torque is transmitted to the output shaft. When the opposite poles face each other they produce minimum saturation of the hysteresis disc and therefore the minimum torque is transmitted to the output shaft. Output torque can therefore be adjusted by adjusting the rotation of the permanaet magnets relative to each other. This is achieved with a simple mechanical arrangement. Because none of the surfaces contact each other the torque setting can be maintained indefinitely.
Advantages of these clutches and brakes include no break-away torque, electricity free operation, constant torque independant of shaft (rotor) speed, no contacting or wearing parts, no friction elements (same torque year after year) and they are operable in some of the most difficult environments.
The various models available cover very low to very high output torques and cover most applications. If you can't see what you want here please contact us to discuss custom made possibilities.

Permanent magnet hysteresis brake - 1 - 8 Nm | BDH series
The BHD series from Kern Motion Technology are brakes equipped with an integrated permanent hystresis. This hystresis is capable of deploying their braking force, without an external voltage supply. These are also an excellent option for torque control, due to the available adjustable and preset versions. In addition, these devices are specifically used in the textile industry, and in general mechanical engineering.

Electromagnetic particle brake - 0.5 - 1.2 Nm
The brake is designed with a control characteristic the same as that of a hysteresis brake, and should be managed steplessly with the use of the exciting current.
Applications with these kinds of characteristics, such as tight winding, winding control, controlled braking, soft start, overload protection and load simulation, are suitable for this unit.
