Open Design. You can start four ways:
- from a generic architecture;
- from a reference machine;
- from a project YAML file;
- from the Sizing wizard.
To use a machine already drawn in CAD, switch Design to CAD import (see Imported CAD machines). A reference machine is a reproducible starting design; its results do not validate your edits.
For a new concept, choose dual rotor / single stator, dual stator / single rotor, or single rotor / single stator. The architecture sets the magnetic circuit and axial stack before you refine dimensions and windings.
02Size, then inspect
The Sizing wizard takes shaft power or torque, speed and DC bus voltage. You can add a diameter ceiling and a continuous controller phase-current limit. Compare the architectures against the same target, inspect the assumptions, then open a candidate as an unsaved design.
Review winding fit, slot fill, current density, geometry and drive warnings as you edit. Set materials and cooling to match the machine you intend to build. Save the project before starting a study.
03Screen variants on Sweep
Sweep runs parameter grids and up to three-objective optimisation at the analytic, 2-D or quasi-3-D tier. Designs whose winding does not fit are marked infeasible and kept off the Pareto front. Open any Pareto design on Design, or queue the chosen ones for a 3-D solve.
04Run a small study first
Simulate is the one page that spends solver time. Start with a single no-load position and inspect its field, linkage and warnings. Follow Run your first field study for a concrete recipe. A back-EMF waveform needs a period calculation, not just one rotor position. For loaded work, calibrate the rotor's d-axis first and check the current convention. A flux map then characterises the machine over a d-q current grid.
Increase grid resolution and angular sampling deliberately before drawing conclusions from torque ripple or cogging.
05Read what it can do
Capability reads stored flux maps and the thermal network in milliseconds. It shows:
- torque–speed envelopes and efficiency maps;
- thermal ratings, warm-up and stall;
- drive cycles;
- rotor mechanics and insulation;
- controller lookup-table export.
Its what-if panels change the drive or cooling without saving. Use Results, Visualize, Compare and Report to inspect, compare and share individual runs.
