Besides the possibility to import the electromagnetic results from third party software, MANATEE is also coupled to FEMM, a free finite element 2d non-linear electromagnetic software.
This means that the geometry & physics of an electrical machine defined using MANATEE GUI can be exported, solved and post-processed using some external electromagnetic software.
The coupling with FEMM includes in particular:
- automated analysis of electromagnetic symmetries depending on topology and load state
- automated build of lamination geometry including windings, magnets, wedges and ventilation ducts, for both inner and outer rotor topologies
- automated assignment of all physical properties including non linear B(H) curves, and boundary conditions independently of rotor to stator positions
- automated meshing with the possibility of user-defined mesh refinement
- automated solving and post processing (torque, energy, airgap flux, flux linkage)
- handling of many electric machines topologies (e.g. induction machines, surface, interior or inset permanent magnet synchronous machines, inner and outer rotor)
- Electrical machines automatically defined in FEMM by MANATEE
MANATEE can also call FEMM for the calculation of
- interior permanet magnet rotor magnetomotive force (for permeance/mmf model) or equivalent magnetization coefficients (for subdomain model)
- saturated slot permeance
- magnetic wedge permeance
- slot leakage inductance
- magnetizing inductances
This module is built in Matlab and can be ordered separately from other MANATEE modules.
