Bought 3 of these from TimeSavers on 3/4/26 for $50 each.
The code A43Rh on a Hansen clock motor refers to a specific model variant in the Hansen Synchron series of synchronous AC timing motors, commonly used in wall clocks, advertising clocks, and other timekeeping devices.Breakdown of the Code (A43Rh)Hansen (now Hansen Corporation) uses alphanumeric codes to indicate motor specifications. The format is typically:A43 = Base model series "A" = Style A mounting (4-hole mounting plate, round gearbox, ~2" diameter × 1-3/8" deep) "43" = Specific geartrain/output configuration (in the 600 Series family) This series is for precise timing applications (1 RPM output common) R = Rotation direction R = Right (clockwise when viewed from the front/shaft end) (L would be Left/counterclockwise) h (lowercase) = Likely a minor revision or batch/suffix code Hansen uses lowercase letters (h, i, etc.) for minor updates, revisions, or production variations (e.g., slight gear changes, winding tweaks, or manufacturing run). It's not a major spec difference — often just a factory identifier. Full Specs for A43Rh (Based on Similar A43RA Models)Speed: 1 RPM (most common for clock hands drive) Voltage: 110V AC (standard U.S. household) Frequency: 60 Hz Power: 3 Watts Rotation: Clockwise (right) Pinion gear: Usually 10-tooth (5.5–5.6 mm diameter) Mounting: 4 tabs/holes (Style A) Compatible movements: Often used in Type C Hansen movements (#610, 143R, A43RA/A44RA series, 288-003, etc.) SummaryA43Rh is essentially a Hansen Synchron A43RA-style motor (1 RPM, 110V 60Hz 3W, clockwise rotation, Style A mount) with a minor revision or production code "h". It's a direct replacement for many vintage wall clocks and advertising clocks that use Hansen motors.If you're replacing it, search for Hansen A43RA (or I43RA variant) — they're widely available (~$40–$60) from clock parts suppliers (Clockworks, Timesavers, Ronell Clock, Griffen's, etc.). The "h" suffix usually doesn't affect compatibility.If you have a photo of the motor or more markings (e.g., full label), I can confirm exact specs or replacement part number!
