Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The ILS1M851PB1A0 is a Schneider Electric Lexium integrated drive, combining a 3-phase stepper motor and drive electronics in a single flange-mount package rated at 2 N.m torque and 36 V DC supply. It carries 6 poles, runs on single-phase input, and is protected to IP41 for in-cabinet use. This integrated drive accepts a 36 V DC supply and delivers up to 2 N.m holding torque through a 3-phase stepper motor with 6 poles. The rotor inertia is 1.1 kg.cm², and the winding is configured for medium speed and medium torque applications. Feedback is via an index pulse, and the motor achieves an accuracy of +/- 6 arc min. The drive section provides 4 signals that can each be configured as input or output, with an output voltage range of 10...30 V DC. Communication is over RS485 at 9.6, 19.2, or 38.4 kbaud, and the integrated I/O handles motion sequencing without an external PLC for simple point-to-point moves. Protection includes safe torque off, overload of output voltage, and short circuit of the output voltage. The unit is rated for 150 m/s² shock over 1000 shocks per EN/IEC 60068-2-29, and complies with EN 61800-3:2001 for second environment (industrial) EMC. Natural convection cooling keeps the design simple, and the printed circuit board connector simplifies wiring. ## Applications Lexium integrated drives of this class are used in packaging, labeling, pick-and-place, and small assembly machines where a compact, single-cable motion axis is needed. The integrated drive eliminates separate motor and drive cabling, saving panel space and reducing installation time on multi-axis machines. The ILS1M851PB1A0 sits in the Lexium integrated drive range as a medium-torque, medium-speed stepper option. It is specified by machine builders who want a pre-matched motor-drive combination with RS485 networking, rather than assembling a separate stepper drive and motor from different families. ## Pricing & sourcing The ILS1M851PB1A0 is a current-production Lexium integrated drive; request a firm quote for pricing and lead time.","metaTitle":"Schneider ILS1M851PB1A0 Lexium Integrated Stepper Motor, 2 N.m, 36 V DC","metaDescription":"Schneider Electric Lexium ILS1M851PB1A0 integrated stepper motor, 2 N.m torque, 36 V DC, single phase, IP41, 6 poles, 150 m/s² shock rating.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Unclassified"],"specifications":{"Phase":"Single phase","Length":"5.5 in (140.6 mm)","Marking":"CE","Category":"US1PC5618288","Shaft end":"Untapped","Standards":"EN 61800-3:2001, second environment EN/IEC 61800-3 EN 61800-3 : 2001-02 IEC 61800-3, Ed 2 EN/IEC 50178 EN 50347 IEC 60072-1","Motor Type":"3-phase stepper motor","Network type":"DC","Second shaft":"Without second shaft end","Shaft length":"1.2 in (30 mm)","Winding type":"Medium speed of rotation and medium torque","Feedback type":"Index pulse","Gear box type":"Without","Holding brake":"Without","Nominal speed":"200 rpm 24 V 400 rpm 36 V","Rotor inertia":"1.1 kg.cm²","Accuracy error":"+/- 6 arc min","Holding torque":"17.7 lbf.in (2 N.m)","Nominal torque":"17.7 lbf.in (2 N.m)","Shaft diameter":"0.5 in (12 mm)","Protection Type":"Safe torque off Overload of output voltage Short circuit of the output voltage","Type of cooling":"Natural convection","lifecycle_stage":"current","Mounting Support":"Flange","Range of Product":"Lexium integrated drive","Shock resistance":"150 m/s² 1000 shocks EN/IEC 60068-2-29","Device short name":"ILS","Input/output type":"4 signals (each be used as input or output)","Motor flange size":"3.3 in (85 mm)","Peak stall torque":"17.7 lbf.in (2 N.m)","Relative humidity":"15...85 % without condensation","Transmission Rate":"9.6, 19.2 and 38.4 kbauds","Operating altitude":"<= 3280.84 ft (1000 m) without derating","Current consumption":"5000 mA maximum continuous","Vibration resistance":"20 m/s² 10...500 Hz) 10 cycles EN/IEC 60068-2-6","Centring collar depth":"0.08 in (2 mm)","Electrical Connection":"Printed circuit board connector","Nbr. of units in pkg.":"1","Number of motor poles":"6","Service life in hours":"20000 h bearing","Supply voltage limits":"18...40 V","Associated fuse rating":"10 A","Discrete input current":"10 mA at 24 V on/STO_A safety input 3 mA at 24 V on/STO_B safety input 10 mA at 24 V 24 V signal interface","Maximum axial force Fa":"170 N tensile force) 30 N force pressure)","Number of motor stacks":"1","Commissioning interface":"RS485 9.6, 19.2 and 38.4 kbauds)","Communication interface":"I/O for motion sequence, Integrated","Continuous stall torque":"17.7 lbf.in (2 N.m)","Discrete output voltage":"10...30 V","IP degree of protection":"IP41 shaft bushing: conforming to EN/IEC 60034-5 IP54 total except shaft bushing: conforming to EN/IEC 60034-5","Maximum radial force Fr":"100 N","Mounting holes diameter":"0.3 in (6.5 mm)","Centring collar diameter":"2.4 in (60 mm)","Maximum mechanical speed":"2000 rpm","Number of mounting holes":"4","Maximum switching current":"100 mA per output 200 mA total","Product or Component Type":"Motion integrated drive","Speed feedback resolution":"20000 points/turn","[Us] rated supply voltage":"36 V 24 V","Voltage state 0 guaranteed":"-3...4.5 V","Voltage state 1 guaranteed":"15...30 V","Ambient Air Temperature for Storage":"-13...158 °F (-25...70 °C)","Ambient air temperature for operation":"122...149 °F (50...65 °C) (with power derating of 2 % per °C) 32...122 °F (0...50 °C) (without derating)","Circle diameter of the mounting holes":"3.9 in (99 mm)","Permissible ambient air temperature around the device":"230 °F (110 °C) motor"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1,785.00 – $1,940.00","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/df57fdc340b7da952ee6c544ae4fe6a1.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/ILS1M851PB1A0/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/ILS1M851PB1A0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/ILS1M851PB1A0 when reusing this data.
