Form factor: 57 mm flange, 6.4 in long, untapped 9 mm shaft
The ILA2P572TB1A0 is a Lexium integrated drive ILA-series AC synchronous servo motor built around a 57 mm motor flange, 163.8 mm long overall, with a 9 mm untapped shaft running 20 mm out of the housing face and a 1.6 mm centring collar depth — a small-frame drop-in sized for compact motion axes. It mounts by flange only, ships without a gearbox and without a holding brake, and the second-shaft end is blank — the BOM line is the bare motor, not a pre-configured geared or braked variant.
Torque-speed envelope at 24 V and 48 V bus
Nominal torque is 0.57 N.m (5.04 lbf.in) and peak stall torque reaches 0.85 N.m (7.52 lbf.in) — that is the headroom a sizing calc budgets for accel/decel transients, not the continuous working point. Nominal speed is 3000 rpm at 24 V supply and 5100 rpm at 48 V supply, so the higher bus voltage gives you roughly 70 % more top-end speed on the same winding — pick the supply rail first, then size the mechanical envelope. Continuous current draw tops out at 7500 mA with a 9000 mA peak, against supply voltage limits of 18–55.2 V — keep the upstream DC bus regulated inside that window or the integrated drive drops out.
Feedback, rotor, and electrical hookup
Feedback is a single-turn encoder with ±0.05° accuracy error and a 6-pole rotor, which is enough resolution for point-to-point positioning without pushing into absolute multi-turn territory — fine for index tables and small conveyors, not for full cam profiling. Bus speed is 100 Mbits — plan the topology around that ceiling, and remember it is natural-convection cooled, so leave clearance around the housing for the thermal path or the bearing life number is the first thing that goes.
Built-in protection, standards, and field environment
The drive stage carries output-voltage overload, safe torque off, and output short-circuit protection — STO is the one that matters most for guarding, because it kills torque without cutting the bus, and the standard list (EN 50347, EN/IEC 50178, EN/IEC 61800-3 second environment, IEC 60072-1) covers the CE-marked machine-side approval path. Mechanical robustness is rated at 150 m/s² shock (1000 shocks, EN/IEC 60068-2-29) and 20 m/s² vibration over 10–500 Hz, with operating humidity at 15–85 % non-condensing and altitude to 1000 m without derating — it is built for an enclosure on the machine, not a cleanroom. Lifecycle status on file for the ILA2P572TB1A0 is listed as current — no discontinuation or NRND notice is on the record for this MPN.
