Electromagnets for Industrial Applications

Our range of Industrial Electromagnetic equipment

Rotary Burnand recently celebrated 120 years of business as a leading manufacturer  of electromagnets and magnetic equipment for industrial applications. Today we have our own comprehensive design, consultancy and test facilities at our premises in Sheffield. Here, we employ a team of highly skilled and experienced staff capable of dealing with all aspects of electromagnetic equipment.  Our services include design, optimisation, consultancy, manufacture, full diagnostic and repair facilities, LOLER testing and electrical certification and magnet control systems. If you have an industrial magnet application we can certainly assist.


Rotary Burnand is a highly respected name the industry and our Burnand magnets are renowned for their robust construction and longevity. We offer a range of standard specifications which cover most handling requirements but we can also manufacture bespoke new electromagnets to meet your exact requirements including deep field, lightweight and bi-pole electromagnets. All our new electromagnets are made to order here at our premises in Sheffield using the highest specification of winding materials and insulations.

We offer a full service including provision of electromagnet control systems, cable management, DC plugs and sockets, and lifting beams.


Rotary Engineering, incorporating the renown Burnand name including all the associated skill and expertise, offer an electromagnet repair service. Electromagnet repairs are a key element of our business and we can return almost any magnet to ‘as new’ specification, so if your lifting magnet has failed we will almost certainly be able to repair it. It's not just Burnand electromagnets that we repair, we can also repair Witton Kramer, Walker, Igranic, Sav Walker, and any other industrial lifting magnet.

Our service starts with a full diagnostic and report on the condition of your magnet. You will then receive a detailed report and itemised quotation to bring your magnet up to “as new” standard. Our service is highly cost effective and our repairs are guaranteed for 6 months. All repaired magnets are LOLER tested and certified on our specially designed test rig prior to despatch.


We also offer LOLER (Lifting Operations & Lifting Equipment Regulations 1998) testing and certification for electromagnets. LOLER testing should be undertaken every 6 months for a lifting magnet. We can LOLER test at your site or here in Sheffield, contact us to discuss your requirements and we will offer you the most cost effective solution.


Any electromagnet requires a magnet control panel for efficient operation. We offer new AC and DC magnet control panels and we can repair your existing control panel. DC Magnet Control panels are now rare but we have the expertise to build you a replacement panel or repair an existing DC Magnet Control panel.


Our expertise is highly valued in industry and so we also undertake design and consultancy projects to evaluate electromagnet lifting for new applications. Our clients include suppliers to aerospace, defence, construction, and automotive sectors.
