Spin’s laboratory is equipped with professional equipment capable of testing all magnetic properties of soft and hard materials and on finished samples including stators, rotating machines, and cores for electromagnets.
Our R&D department is constantly researching innovative materials to optimize customers’ devices and designs, and implementing automated and customized measurement setups.
We develop user friendly interfaces capable of returning accurate results in a short time including: Static Field Permeameter (DC), Coercimeter and AC Permeameter.
Measurements and material tests carried out in our laboratory comply with standards:
- IEC 60404-3 AC permeability and losses for electrical steel
- IEC 60404-4 DC permeability, coercivity and remanence
- IEC 60404-5 permanent magnets
- IEC 60404-7 coercimeter
- IEC 60404-15 feebly magnetic materials
The available material analyses and tests are as follows
| Samples | Type of analysis |
