Noncontact Electric Clutches

GERWAH™ Hysteresis & Synchronous Couplings -- MKS
from Ringfeder Power Transmission USA Corporation

GERWAH's couplings from the 'MKS' series are a special modification of the permanent magnetic synchronous coupling MKD with an extended air slot. Especially in pumps, the system displays all its advantages. It allows torque transmission into a hermetically sealed container, for example, so that the... [See More]

  • Shaft: In-line
HC Electromagnetic Hysteresis Clutch -- HC-0.5
from Ogura Industrial Corp.

FAST RESPONSE. The torque of H series electromagnetic hysteresis clutches and brakes is independent of slip speed. Torque is directly proportionate to coil current, thus the torque of each unit can be adjusted by varying the current. Once the current is stable, the torque remains constant. LONG... [See More]

GERWAH™ Magnetic Hysteresis Couplings -- HKD
from Ringfeder Power Transmission USA Corporation

GERWAH's permanent magnetic hysteresis coupling from the 'HKD' series consists of two separate unsupported halves. The coupling is connected with the shaft by means of clamping hubs. Thanks to its pioneering concept, HKD transmits torque smoothly in a 'sliding' manner which is completely wear-free. [See More]

  • Shaft: In-line
GERWAH™ Magnetic Hysteresis Couplings -- HLV
from Ringfeder Power Transmission USA Corporation

A slim design and flexible mounting possibilities: the magnetic hysteresis couplings from the 'HLV' series can be used for many purposes. Their rated torque level can be adapted individually thanks to a user-friendly scale. On request, HLV is available in stainless steel, too. Especially in the... [See More]

  • Torque: 0.3 to 2.9
  • Shaft: In-line
GERWAH™ Magnetic Hysteresis Couplings -- HSV
from Ringfeder Power Transmission USA Corporation

The compact design and the flexible mounting possibilities of GERWAH's magnetic hysteresis coupling 'HSV' open up a wide field of possible applications. Its innovative concept qualifies this element for use in bottle capping machines as well as in roll-up and unroll systems, and in test engineering. [See More]

  • Engagement: NonContact
  • Magnetic Type: Hysteresis

  • Shaft: Parallel
GERWAH™ Magnetic Synchronous Couplings -- MKD
from Ringfeder Power Transmission USA Corporation

The permanent magnetic synchronous coupling 'MKD' consists of two separate halves which have to be supported by the customer and are then telescoped. The special feature of MKD: the maximum transmittable torque can be changed by modifying the hub submergence. At overload status, the coupling will... [See More]
