SED Electromagnetic Tooth Clutch

SED Electromagnetic Tooth Clutch

The SED electromagnetic tooth clutch is a positive clutch, i.e. current driven. When a DC voltage is established in the coil, a magnetic field is generated that crosses the toothed rotor and attracts the armature, transmitting the movement.

It is characterized by its small dimensions in relation to its high torque transmission capacity and its self-centering inductor-coil arrangement by bearings.



What is the SED electromagnetic tooth clutch?


The SED electromagnetic tooth clutch is a highly relevant component in a wide variety of industrial and mechanical applications, thanks to its unique characteristics that make it ideal for torque transmission in confined spaces and demanding environments.

Efficient operation

The SED electromagnetic tooth clutch is known for its efficient and reliable operation.

It is a positive clutch, which means that they are activated by electric current.

When DC voltage is applied to the coil, a magnetic field is generated which passes through the toothed rotor, attracting the armature and transmitting the movement precisely and without slippage.

This feature makes them ideal for applications requiring precise torque transmission without power loss.

Versatility of application

One of the key advantages of the SED electromagnetic tooth clutch is its versatility in application.

They can work in any position, making them suitable for a wide range of machine configurations and designs.

In addition, they are suitable for use in lubricated environments, which further extends their versatility and adaptability to different working environments.

Ideal for small spaces

These clutches are characterised by their small size in relation to their torque transmission capacity.

This makes them the perfect choice when faced with space constraints in machine design.

Its self-centring, ball-bearing inductor-coil design contributes to its efficiency and reliability in motion transmission.

Minimal maintenance

One of the most attractive aspects of the SED electromagnetic tooth clutch is that they require little or no maintenance.

This is due to its robust design and its ability to function reliably in adverse working conditions.

By choosing these clutches, companies can reduce maintenance costs and machinery downtime.

Various applications

The SED electromagnetic tooth clutch is used in a wide range of industries and machines.

It is ideal for machines that require high levels of torque transmission, as well as for those where slippage needs to be avoided.

They are also an excellent choice in systems with variable inertias, as they allow disengagement at any rotational speed. From the automotive industry to industrial machinery, these clutches are essential in numerous applications.

Mounting options

The SED electromagnetic tooth clutch offers versatile mounting options.

You can join two shafts in line by means of a flexible coupling, or connect shafts in parallel using sprockets, pulleys and other motion transmission solutions.

This gives designers and manufacturers flexibility in the configuration of their systems.

Highlights of the SED Electromagnetic Tooth Clutch


  • Girth gear drive without slip rings: One of the outstanding features of SED toothed electromagnetic clutches is their ability to transmit motion through a ring gear. This approach eliminates the need for slip rings, which simplifies design and reduces the possibility of wear and failure associated with slip rings in rotating systems.
  • Possibility of synchronism: An important feature of the SER is its self-supporting design. This means that the clutch is capable of supporting loads and working independently, making it ideal for a variety of drive systems.
  • Standard voltage of 24 V.d.c.: SED electromagnetic toothed clutches operate on a standard voltage of 24 volts direct current (V.d.c.). This standard voltage facilitates integration into a variety of systems and applications and provides safe and efficient operation.


The SED Electromagnetic Tooth Clutch can be used for different types of machinery, such as:
