Calculators by WiredWhite engineers: inputs, formulas you can read, results, charts and drawings, checked against reference cases. They run in your browser.
Wired White v1 Magnetic field, cogging torque, back-EMF, inductance and torque of a surface-magnet machine with open radial slots and optional stator flux barriers, from an analytical subdomain model (Fourier series in each region, solved as one linear system).
Wired White v1 Estimate steady-state junction, case, and sink temperatures and a single-pulse junction rise from a four-term Foster model.
Wired White v1 Calculate the cutoff, gain, phase, Bode response, and step response of a passive first-order RC low-pass filter.
Wired White v1 Size the inductor and output capacitor of a continuous-conduction buck converter and inspect its triangular inductor current.
Wired White v1 Slot layout of an m-phase winding, winding factor and MMF spectra, and the MMF along the air gap as the currents turn (â–¶): the working wave travels with the rotor, the others at their own speeds, some backwards. Even numbers of phases and flux barriers in the stator yoke.
