Fast electrical machine set-up


Manatee V2.2.3 can simulate:

Manatee comes with a complete set of electrical machines templates to be able to quickly define the magnetic circuit geometry. Predefined slot shapes and magnet shapes allows to perform parameter sweeps on the topology.

The winding pattern is automatically defined using star of slot method, widely used by electrical engineers. Special slot or magnet pocket geometries can be defined using slot .dxf import and magnet pocket .dxf import features.

Several topological particularities can also be easily defined:

  • different skew patterns are available (linear, V-shape, zig-zag or user-defined)
  • uneven pole distribution can be taken into account (e.g. different North and South poles)
  • different sets of ventilation ducts and notches can be added to the stator and/or the rotor bores, either in a parametrized shape or using .dxf import

Manatee also comes with a series of electrical machines that have been already defined and used for validation purposes (e.g. Toyota Prius, Audi e-Tron). Manatee is compatible with Pyleecan open-source software, so any electrical machine that has been defined in Pyleecan can be imported in Manatee.


The electrical machine magnetic circuit can be defined by both electrical engineers and mechanical/NVH engineers based on a limited number of input parameters. Electrical machine files can be easily shared among engineers as .json files.
