Every rotating permanent magnet generator fights itself at the moment of maximum field coupling — when rotor magnet aligns with stator pole. That alignment point is also peak cogging force. Peak EMF and peak resistance at the same moment. The generator is working against itself. 140 years of combustion engines showed the solution: extract at 38.17° before dead center — the phi offset — not at dead center itself.
At direct pole alignment: maximum EMF AND maximum magnetic resistance simultaneously. The Pelton wheel fights the generator's own alignment force. 3-8% of output wasted every revolution. Pulsed bearing axial load. Vibration at pole frequency. All preventable.
arcsin(0.618) = 38.17°. Peak dΦ/dt occurs here — not at peak alignment. This is where EMF peaks. Capture it here. Then retract the magnet through dead center with increased gap. Cog force drops by gap² law. Free rotation after.
Peak EMF captured at phi offset. Dead center bypassed. Cog reduced 75-90%. Bearing axial load near zero (dual-ring). Output frequency doubled. Vibration eliminated. 3-8% recovered from same water, same magnets, same stator.
Each active magnet pivots on a pin fixed to the rotating wheel. Two or three fixed permanent magnets inside the wheel drive the magnet to the correct position at the correct angle. The cam trips a latch to release the holder. The groove is the seatbelt — never touched in normal operation.
Active magnet on pivoting arm. Pin fixed to wheel. Pin = hinge — carries no load. Outer arm carries magnet. Swings OUT at phi offset toward stator. Swings IN through dead center away from stator. No spring. No bearing.
All fixed magnets INSIDE the wheel — between hub and active magnets. No outer housing magnets.
+ push magnet: N→N repels active OUT at 38.17° before dead center.
− pull magnet: S←N attracts active IN at dead center.
Cut inside wheel. Pin sits loosely. NEVER touched normally. Catches pin only on magnet failure. Groove wear = diagnostic signal: a fixed magnet has weakened. Service required.
Seatbelt · not steering wheel.
The critical geometry: all fixed positioning magnets are located INSIDE the rotating wheel — between the hub and the active magnets at the outer edge. The housing is only the stator. The entire mechanism is self-contained within the wheel assembly. This makes the wheel a drop-in replacement for any existing stator.
Location: inside wheel, between hub and active magnets, at phi offset angular position (38.17° before stator pole dead center).
Polarity: North pole faces inner face of active magnet. N→N repulsion pushes active magnet OUTWARD toward stator. Minimum gap. Maximum coupling. Peak EMF captured.
Location: inside wheel, between hub and active magnets, at dead center angular position (stator pole direct alignment).
Polarity: South pole faces inner face of active magnet. S←N attraction pulls active magnet INWARD away from stator. Gap increases. Cog drops by gap² law.
The cam does NOT drive the magnet. The cam trips a small latch. The latch has two stable positions: OUT lock (active magnet extended toward stator) and IN lock (retracted). The inside fixed magnets drive the holder between positions once the latch releases. The holder snaps — fast dΦ/dt — higher EMF than gradual movement. The latch is the EMF amplifier.
| Mechanism | Cam force | Cam wear |
|---|---|---|
| Direct cam drive | 100-400 N (magnet force) | High · limited life |
| Cam-latch (this) | 0.5-2 N (latch spring) | Near zero ✓ |
| Reduction | 200-800× | Effectively infinite life |
The cam trips the latch at 3-5° before the inside magnet comes into range. The field drives the holder to the new position. Cam locks the latch at the new position.
The latch holds flux constant between snaps (dΦ/dt=0). Releases to snap. Maximum contrast. Maximum EMF pulse.
Instead of individual pivot holders, the entire BLDC outer ring shifts axially along the shaft. One mechanism moves all magnets simultaneously. The shaft has a sinusoidal phi ratio groove cut into its surface. As the ring rotates, a pin follows the groove. Ring shifts IN at phi offset — maximum axial overlap, peak EMF. Ring shifts OUT at dead center — reduced overlap, cog reduced. Applies to every BLDC outrunner ever built.
The first sketch showed a wavy rod beside the outer wheel. Initially interpreted as a housing-wall groove for a pin follower. Now correctly understood: the wavy rod IS the shaft, with the sinusoidal phi ratio groove cut into its surface. The ring pin rides this groove. The shaft is the cam. The groove is the timing. One machined profile. Works forever.

| Snap-action EMF | +15-40% ✓ | No (gradual) |
| BLDC retrofit | Harder | Easier ✓ |
| Best for | High performance | Global BLDC retrofit |
The balanced dual-ring shaft has two half-screw groove sections with a 180° phase twist at the center. As the shaft rotates, the left ring shifts IN while the right ring shifts OUT simultaneously. Axial forces cancel. Bearing load: near zero. Output frequency: doubled. The mechanism is not original — Earth has run this exact compensation system since its formation.

Earth has been compensating its rotational asymmetries through dual-period wobble for 4.5 billion years. The balanced dual-ring shaft applies exactly the same principle to generator cog compensation. No additional mechanism required. The geometry does it.
The output envelope carries a slow beat frequency — the result of the two rings' phase offset. This beat IS the health indicator. No sensors needed. No electronics. Just measure the output envelope.
| Beat condition | Meaning |
|---|---|
| No beat (exact 180°) | Perfect cancel · no diagnostic |
| Slow stable beat (137.5°) | Healthy · optimal ✓ |
| Beat growing | Phase drifting · inspect pins |
| Rapid beat | Service required |
The geometry self-reports its own condition. Silence is not golden here — the slow beat at 137.5° tells you everything is right.
The Tidal Pulse Tower generator is the only rotating element with a cog problem. All other Tower innovations operate without cogging issues. Adding pivot-field mechanism to the Tower PMG is a drop-in generator upgrade — no changes to ARM A, ARM B, Pelton wheels, siphon, or stator.
The HGG is a closed batch system — fixed water mass cycling between two chambers. No variable incoming pressure to bypass. The pivot-field generator upgrade applies to the HGG Pelton shaft. HGG regulation is a phase timer — not a bypass gate.
HGG is closed — no bypass gate. The regulation question is WHEN to flip, not how much flow.
