Projects - High Speed Electric Motors

High Speed Electric Motors

Both electromagnetic and mechanical finite element modelling are powerful tools for designers of electric machines. For high-speed applications, some examples of the areas where Best Solution can provide modelling support are: Rotor containment can losses (caused by modulation of rotor field by stator teeth) Rotor stress distribution resulting from shrink fitting of containment cans Rotor …

Best Solution - Projects - Permanent Magnets

Permanent Magnets

Many permanent magnet materials exist today, with the most common being ceramic or ferrite materials, where reasonable performance at very low cost is required. Other common materials include the high energy rare-earth types, plastic or resin bonded ferrite and rare earth variants, and cast alloy types, which are old-fashioned but still important in some areas. …

Projects - Variable Reluctance Resolvers and Brushless Resolvers

Variable Reluctance Resolvers and Brushless Resolvers

Best Solution can provide bespoke designs for resolvers including variable reluctance resolvers, for specific customer requirements. We have produced designs for customers including 2 pole and 24 pole frameless (sometimes referred to as “slab” or “pancake” ) variable reluctance resolvers for rotor position sensing in motor control applications. Resolvers have been around for many years, …

Projects - Magnetic Surgery

Magnetism in Surgery

Best Solution supported Oxford instruments in the development of a magnetic system designed for a pioneering surgical technique. The system would potentially allow surgeons to steer a catheter with a small magnetic tip through the brain, by rapid adjustments to the magnetic fields of three orthogonal superconducting coils around the patient’s head. The tip could …

Best Solutin - Projects - Best Solutin - Projects - MRI Magnetic Shielding

MRI Magnetic Shielding

Best Solution has assisted manufacturers of MRI scanner magnets using magneto-static finite element models. The models typically include the large superconducting magnet of the scanner and a soft iron shield which is normally included in the fabric of the building housing the scanner. The permissible leakage fields are small for these installations, and we work …

Best Sulution - Magnetic Linkages

Magnetic Linkages

Magnetic linkages are often designed into equipment where it is desirable to separate different sections of the same mechanism. This could be required for a number of reasons, but most commonly it is because two different environments need to be isolated from each other, e.g. Thermal isolation – mechanical work is transferred through a barrier …

Best Solutin - Projects - Best Solutin - Projects - Magnetic and Electric Field Shielding

Magnetic and Electric Field Shielding

Magnetic shield and screen design can be a challenging area. Magnetic shields are made from soft magnetic materials i.e. those with very high permeability. Shield thickness is important, as any saturation in the shield material will make drastically reduce its shielding properties. Best Solution uses leading finite element software for magnetic field analysis. For shielding …
