Sizing the 37 N.m frame against the load cycle
The MH31903P16A2200 sits in the MH3 family and carries the MH31903P sizing reference on its nameplate (cites:,), so a Lexium 52 or Lexium 62 drive of the matching rating is the natural pairing the catalogue builds around. At nominal, the same 327.5 lbf.in (37 N.m) point holds whether the drive is an LXM52 or LXM62 on 400 V or 480 V three-phase (cites:), which means the BOM position is interchangeable across the two drive families without a torque derate.
Mechanical fit on the machine
Mounting is the international standard flange pattern (cites:) on a 7.5 in (190 mm) bolt circle (cites:), with four 0.6 in (14 mm) mounting holes (cites:,) and a 7.09 in (180 mm) centring collar seated 0.2 in (4 mm) deep (cites:,). Shaft end is a parallel-key 1.5 in (38 mm) diameter by 3.1 in (80 mm) long with a 0.4 in (10 mm) key (cites:,) — a standard coupling and gearbox input that does not require a custom-machined adapter. Radial load handling drops from 3300 N at 1000 rpm to 3100 N at 4000 rpm on the catalogue curve (cites:), and the maximum mechanical speed ceiling is 3800 rpm (cites:) — for a belt or pinion drive the buyer is choosing between shaft speed and overhung load, not treating them independently. Overall length is 12.2 in (310 mm) (cites:), so cabinet depth and the cable-bend radius behind the motor both need to be checked before commit.
Feedback, brake, and electrical connection
Feedback is a single-turn SinCos Hiperface encoder (cites:), the resolver-free digital protocol that the Lexium 52 and Lexium 62 drives accept directly — no add-on encoder card needed in the cabinet. There is no holding brake on this build (cites:) and no second shaft end (cites:), so vertical-axis applications that need a fail-safe brake must add it externally or pick the braked variant of the MH31903P sizing reference. Power and signal land on rotatable right-angled connectors (cites:), which lets the wireman orient the cable exit after the motor is bolted down instead of fighting the gland during mounting.
Thermal envelope and sealing for plant duty
Sealing is IP65 standard (cites:), which covers dust-tight and low-pressure water-jet exposure — appropriate for typical plant floors and most washdown-adjacent areas, though it is not the IP67K rating called for on direct food-zone spray-down. Continuous power at nominal is listed at 9560 W (cites:); the same row also lists 7.75 W as a 'nominal output power' entry (cites:), which is a data-entry artefact rather than a usable figure — the 9560 W continuous power entry is the rating that drives the cooling and cabinet-sizing decision.
Sourcing posture for the BOM line
No official second source or successor cross-reference is on file for this code, which is normal for a configured servo motor — the variant suffix fixes the encoder, brake option, shaft, and connector combination, so a 'replacement' must match all of those fields, not just the torque rating.
