Overview
The ILS1U853PB1A0 is a Schneider Lexium integrated drive — a 3-phase stepper motor with integral drive electronics, rated at 6 N.m (53.1 lbf.in) holding torque on a 36 V DC supply. It carries CE marking, is rated IP41, and mounts via flange.
This unit combines a 6-pole 3-phase stepper motor and a drive in one housing, accepting pulse/direction 24 V signals for position control. The 6 N.m holding torque suits direct-drive indexing or low-speed positioning without a gearbox. Rotor inertia is 3.3 kg.cm², and winding resistance is 20.0 ohms — figures that inform acceleration limits and thermal behaviour under repeated start-stop cycles.
Applications
Integrated stepper motors of this class are used in packaging, labelling, pick-and-place, and small assembly machines where a compact, single-cable motion axis is preferred over a separate drive and motor. The 36 V DC supply and pulse/direction interface fit into existing PLC-based motion architectures without fieldbus commissioning.
Within Schneider's Lexium integrated drive range, the ILS1U853PB1A0 sits as a medium-torque, medium-speed variant — 6 N.m at 36 V — bridging the gap between the lower-torque ILS1F57x series and the higher-speed ILA servo-integrated units. It is specified by machine builders who need a single-source motion component with CE and IEC 61800-3 compliance for second-environment installation.
