Switching and control engineering visualized in 3D — from the contactor to motor control.

A cutaway three-phase asynchronous motor: three phase-colored pulsing windings create the rotating field (sum vector visible), the squirrel-cage rotor follows with slip. Frequency, pole-pair number (n = 60·f/p), load and phase swap L1↔L3 adjustable live — in sync with the sine-curve and vector diagram.

A cutaway model of a contactor switches a three-phase motor: pushbuttons S1/S0, coil, armature and contact bridges live — latching via K1 13/14 can be switched on/off (jog mode vs. restart protection), circuit diagram with live-colored current paths.

Decode harmonized cable designations: H07RR-F 2G1,5 & co. Assemble it building block by building block; the 3D cable section in a stepped cut (sheath, standard-colored cores, conductor pattern) builds up live — including course presets and a mini quiz.

Contact opening under load in super slow motion: the arc ignites, travels and extinguishes at the current zero crossing — AC vs. DC, four suppression concepts (free, deion plates, RC element, varistor) with a synchronous U/I plot and accumulating contact erosion.

The tripping characteristic on a double-logarithmic scale, hands-on: setting and motor current via slider, overload in time-lapse up to thermal (bimetal) or magnetic tripping — with an animated functional model, a conveyor-belt practice exercise and a comparison of motor protection switch ↔ relay.

The same motor control in four representations: overview diagram, function diagram, detailed representation and contact mirror + device list — two views side by side, hovering a component highlights it synchronously in all, optionally with a clickable simulation.

A card quiz on 20 circuit symbols per DIN EN 60617 — match names and auxiliary/main contact category, with terminal designations (A1/A2, 13/14, 95/96), score, streak and a filterable learning grid of all symbols.

Five classic control projects (lifting platform, irrigation, blower, conveyor system, paint booth) as live-simulated circuit diagrams in detailed representation — press pushbuttons in the diagram, current paths light up, contactors pull in. With wire-break fault finding via voltage measurement.

Motor with a heavy inertial flywheel (flying shear): direct start vs. Y start compared — I(t) and n(t) curves live, the winding schematic morphs between star (230 V, ⅓ current) and delta (400 V). Switch manually or via a timer relay; switching too early reveals the current surge.

Reversal of direction by phase swap: a complete circuit diagram with K1/K2, latching and break-contact interlocking. Interlock can be disabled — anyone who then switches both directions provokes the phase short circuit with a flash and tripping fuses.
