A lot of graphical post-processings are already defined within MANATEE. All of them are listed in the plot_all.m script. Only part of them is reviewed in this chapter, please refer to plot commands documentation for their complete description or run the plot_all script (requires a lot of graphical memory at up to 100 graphs can appear).

As the standard outputs of MANATEE are the structures Input and Output, most of the plot functions look like "*plot_something(Input,Output)*".

To make it easier to use them, they have been scripted to use the default Input and Output structure of the workspace so that you can simply call them by typing "*plot_something*" in the command line.

One first important graph to plot is the geometry with plot_machine :

Note that it is a 3D graph. It can be used to check if the geometry has been correctly defined.

The winding pattern can be plotted with plot_wind :

The upper graph show the coils phase number and the direction of the current (+ towards you, x opposite to you) in each slot along the airgap, in anti-clockwise direction. All the angular graph are plotted in trigonometric direction. The period of the winding is automatically calculated. One can notice the coil pitch of 5 slots.

The lower graph shows the winding functions with linear increase in the slots, and the results total magnetomotive force.

For a better overview of the stator mmf one can use plot_smmf_space

This graph allows to quantify the harmonic content of the stator mmf. One can find that the main space harmonic is 3 (red bar), which corresponds to the pole pair number. Due to the winding discretization in the stator slots some additional space harmonics of wavenumbers Zs-p=33 and Zs+p=39 are present.

Note that all the Fourier transforms along the airgap angle are given by default in spatial frequencies, not in pole pair numbers. To change that in « space orders » (1 for one pole pair) one can set **Input.Plot.is_spatial_order=1**

Similarly, all graphs involving frequencies can be displayed at a function of the electrical order, i.e. the proportionality coefficient with the fundamental electrical frequency.

As an example the time evolution of the stator current linkage is given by plot_smmf_time

One can see that it is purely sinusoidal as there is no converter harmonics. The fundamental is at 60 Hz. To change to electrical order one can set **Input.Plot.type_electrical_order = 1**
