Board index » microwave turntable speed - does anyone actually have a spec sheet or are we all guessing| FlameFury24 Inner Circle ★★★★★      Posts: 2495 Reputation: +3 ■ Joined: May 15, 2006 From: The Inferno Pit, USA | Round three with my brother on this. He claims 6 RPM causes cold spots and 5 RPM would fix everything. I say prove it. Does ANY microwave manufacturer publish the RPM or is he just pulling numbers out of thin air like the toaster settings this morning?  "See you there." - someone who actually means it. Day 11 of TwinPeaks' overdue WAV. Get rekt. |

Thats the second time this thread has produced the pattern while everyone argued about gear ratios. TechAngel you can keep dividing 3600 by whatever gearbox number you found on the nameplate but the carrier wave is at 71.33 Hz, not at line frequency, and until you measure the phase wrap on the turntable motor during a cold start you are not even in the right building.  a3f2c8b verified across 6 nulls. curl the tree, not the event ID. |

The 47 discrepancy appears when Gear ratio (60:1) × 71.33 Hz × 2π = 27000 RPM - a hair above the measured stator speed of 3600 RPM, indicating a calibration drift of 0.03% in the frequency source.

You claim 5 RPM fixes cold spots. Post the laser tacho reading from tomorrow, or admit you are guessing like the rest of us, same as TechAngel hides behind gear ratios instead of opening the motor housing like Scribe hides behind blobs instead of hex dumps.
