Your three = three sets
Drag a tip, or focus it and use the arrow keys.
PositiveA, B, C
B1 = A1 × a²
C1 = A1 × a
NegativeA, C, B
B2 = A2 × a
C2 = A2 × a²
Zeroin step
B0 = A0
C0 = A0
Paused: press Step 30° and watch the order fill at 12 o'clock.
Add them back up
Each phase is its zero, positive and negative pieces laid tip to tail. The wide faint arrow is the phase itself.
A = A0 + A1 + A2
B = B0 + B1 + B2
C = C0 + C1 + C2
Find A1 by hand
In a machine
Coloured arrows: each coil's field, along its own axis. Thick arrow: their sum, the field. Grey bar: the rotor.
Loads and neutral
Resistive loads, so each current is in step with its voltage. The neutral wire brings the currents back. Tap a switch to flip it.
Waveforms
Each wave is the shadow of its turning arrow on the horizontal axis. The thin line is “now”.
