## Description

Manatee software accelerates the calculation of magnetic loads using the concept of **Magnetic** **Look Up Tables** (MLUT) as a function of speed (e.g. along max torque/speed curve) or function of current supply (e.g. Id/Iq in whole torque/speed plane for a traction synchronous motor).

A limited number of operating points are calculated and operational magnetic loads are either interpolated or extrapolated depending on the control law of the electrical machines. As an example, in open-circuit operation of PMSM, **Load Extrapolation Algorithm** is used. On the contrary, along the constant load angle starting phase of a traction PMSM motor, **Load Interpolation Algorithm** is used.

MLUT calculation is compatible with **skewing**, **flux density import** feature, and can be accelerated using **parallelization**. Operating points can be automatically defined or manually defined.

## Application

Operational loads can be quickly calculated by **electrical engineers** along max torque / speed curve or in the full torque / speed plane using MLUT. This MLUT can be imported by **mechanical engineers** and **acoustic engineers** to complete e-NVH calculations on their own.
