Electric machines

Only rotating AC machines with cylindrical cores with inner rotor are included into this version of DriveConstructor. It is possible to choose between:

• SCIM – Squirrel Cage Induction Machine (Fig.1),
• SyRM – Synchronous Reluctance Machine (Fig.2),
• PMSM – Permanent Magnet Synchronous Machine (rotor shown in Fig.3) and

SCIM, PMSM and SyRM can be selected for any application and any drive train topology. SyRM are available for quite limited range of powers. So far only LV SyRM products are known, therefore only LV FC can be used to drive SyRM.

Performances of the machines of different types are different. Usually:

• Efficiency (DFIM) = Efficiency (SCIM) < Efficiency (SyRM) < Efficiency (PMSM)
• Cost (DFIM) = Cost (SCIM) < Cost (SyRM) < Cost (PMSM)
• Size (DFIM) = Size (SCIM) > Size (SyRM) > Size (PMSM)
