What the motor is and where it drops into a cabinet
The Schneider Electric MH3 series servo motor MH31902P06A2200 is a three-phase brushless servo with a 190 mm international-standard flange — the unit that drops onto the gearbox or directly couples to the load in a machine module. It is sized against the MH31902P reference, ships with a single-turn SinCos Hiperface encoder on a smooth 38 mm shaft, and carries no holding brake or second shaft end — so the brake logic and any secondary feedback path live on the drive side or a coupled axis.
Torque envelope, speeds, and what 29 N·m actually buys you
Nominal torque is 29 N·m (256.7 lbf.in) when driven from an LXM52 or LXM62 at 400 V or 480 V three-phase, with a nominal speed of 2000 rpm on either drive — meaning the continuous working point sits at that current and that speed, not at the peak. Peak stall torque reaches 220 N·m (1947.2 lbf.in) from 115…480 V three-phase, and continuous stall torque is 48 N·m (424.8 lbf.in) over the same voltage window — the three-fold gap between continuous and peak is the headroom sized for acceleration ramps, not for steady-state output. Continuous power reaches 6.07 kW at 400 V and at 480 V, with a maximum mechanical speed of 3800 rpm and a 10-pole rotor — above the 2000 rpm nominal point, the torque falls off as speed rises, so the machine's working envelope lives below that ceiling.
Mechanical fit, electrical hookup, and where it survives
Mounting is an international-standard flange with a 180 mm centring collar recessed 4 mm and four 14 mm mounting holes on the 190 mm bolt circle, suited to a standard servo mounting pattern — the centring collar takes the shear so the dowel pins locate the motor relative to the gearbox input, not the bolts alone. Electrical hookup is via rotatable right-angled connectors, no holding brake, and natural convection cooling with an IP65 standard seal on the body — the IP65 rating covers water-jet cleaning and dusty cell environments, but submerging the body or running it in a washdown booth requires a higher-spec sealed variant. Maximum radial load on the shaft runs from 3200 N at 1000 rpm down to 2950 N at 4000 rpm, with a continuous stall current of 30.8 A and a peak Irms of 114 A — the radial-force derating curve is the figure to check when a helical gearbox or a belt drive is hung off the shaft extension.
Sourcing posture for the spare-cabinet buyer
The MH31902P06A2200 part structure — MH3 platform, 190 mm frame, MH31902P winding — is the identifier an integrator uses to match it to an existing LXM52 or LXM62 axis when a motor fails and the production line cannot wait for a redesign.
