Free guide to electromagnetic clutches and brakes

Techdrives has published a free guide to electromagnetic clutches and brakes that will help design engineers specify the right product and integrate it into their machine designs so as to maximise the benefits and avoid common pitfalls.

Electromagnetic clutches and brakes are old technology that has changed little in the past 20 years. Decentralised drives have reduced their use but many applications remain where the ability to connect, disconnect, stop and hold is irreplaceable. Techdrives' free guide examines friction clutches and brakes that use electromagnetic force to engage, usually provided by a 24V DC supply. Different types of design are examined, with a description of how each one works. The guidance describes the common pitfalls in mounting and makes recommendations to the design engineer on the most efficient way to incorporate them into a machine in order to maximise the benefits.

Electromagnetic clutches and brakes have largely become standardised in Europe, with near-interchangeable dimensions. Torques are typically in the range 3-500Nm although there are niche exceptions, even up to 2000Nm or more. Typical shaft sizes are 5-80mm.

For the vast majority of applications electromagnetic clutches and brakes can be considered as maintenance-free units, although engagement at high speeds will result in the need for occasional adjustment for wear. The norm is to use a low-voltage DC supply, usually 24V DC but other voltages up to 48V are possible.

Here in the UK, Techdrives offers the INTORQ range of electromagnetic clutches and brakes, previously marketed until 2003 under the Simplatroll and Lenze brands. Follow the link to download a copy of the free guide to electromagnetic clutches and brakes.
