Samarium
Frequently asked questions
| What kind of motors can Samarium design? |
Samarium can design permanent-magnet surface-mounted brushless DC three-phase motors. It can design outer and inner rotor motors. It can also design slotted and slotless motors.
Samarium cannot design buried magnet motors or motors with a different number of phases. |
| What kind of magnet geometry does Samarium support? |
| Samarium supports ring, arc, and breadloaf magnets for inner rotating motors. For outer rotating motors, ring and arc magnets are supported. |
| Are multi-pole ring magnets supported? |
| Yes, any number of magnet poles can be specified. The practicality of magnetizing the permanent magnet is not considered. |
| What kind of elements are available in Samarium for finite-element analysis? |
| Samarium produces constrained Delaunay triangulations. First, second, and third order triangles can be generated. |
| Does Samarium support parallel processing of FEA? |
Parallel processing can be optionally used when generating a series of FEA runs or steps with certain parameters changing at each step.
For example, the rotor may be rotated by 180 degrees in steps of 5 degrees. This results in 36 separate steps. Four separate threads can be started, meaning that each one will only have to work on 9 steps, significantly speeding up the process. This is useful only when the computer running Samarium supports and is populated with multiple processors and / or multi-core processors. If incorrectly used, this will not result in any time being saved. |
| What is the optimal number of threads for FEA? |
Samarium currently supports a maximum of four threads. The maximum recommended number of threads varies depending on the number of processor cores available:
- One single-core processor = 1 thread
- One dual-core processor = 2 threads
- Two single-core processors = 2 threads
- One quad-core processor = 4 threads
- Two dual-core processors = 4 threads
- Four single-core processors = 4 threads

| How are license files used to authorize Samarium? |
Licensing Samarium involves running a small hardware signature gathering application on your PC. We will make the license files for your PC based on the results. Instructions on how to authorize Samarium will be sent along with the license files.
Please ensure that there are no additional or unwanted devices connected to your PC when running the hardware signature application. If the hardware signature is not the same when Samarium tries to run, it will not function correctly. It is recommended that a dedicated computer be reserved for running Samarium.
