It delivers 2.9 Nm nominal torque and 3300 rpm at 400 V three-phase supply, with torque rated for 208 V and 480 V lines as well. Feedback is absolute single-turn SinCos Hiperface, providing position data on power-up without a homing cycle — a direct fit for drives supporting the Hiperface protocol. The 10-pole, 3-stack rotor design gives 25.6 mH stator inductance and 1.41 Nm/A torque constant at 20 °C, which sets the current-to-torque gain for tuning the drive loop. ## Electrical and performance characteristics Supply voltage range is 208…480 V three-phase, 50/60 Hz. Nominal output power is 900 W on 400 V or 480 V and 450 W on 208 V. Continuous stall torque is 3.4 Nm across the voltage range, with peak stall torque of 8.6 Nm regardless of line voltage. Continuous stall current is 2 A; maximum RMS current is 12.5 A across all three-phase voltages. The 3-second peak current is 6 A. Back EMF constant is 95.39 V/krpm at 20 °C, and stator resistance is 7.99 Ω — these values guide the drive's current loop and velocity loop tuning. Cooling is natural convection, so the motor relies on free air movement. IP65 rating allows installation in washdown and dusty environments without external protection. ## Mechanical interface and mounting Motor flange size is 70 mm (2.8 in) with an international standard flange pattern, centring collar diameter 60 mm and depth 2.5 mm. Shaft diameter is 14 mm (0.6 in), shaft length 30 mm (1.2 in), untapped, no second shaft end. Maximum radial force varies with speed: 730 N at 1000 rpm down to 400 N at 6000 rpm. Maximum axial force is 0.2 × Fr. Electrical connection is via a printed circuit board connector. Overall length is 300 mm (11.8 in), which includes the connector and shaft protrusion. Mounting holes are 5.5 mm diameter on the flange. No successor or cross-reference is documented; the motor is the current offering in this frame size and feedback type.","metaTitle":"BMI0703P26A Servo Motor, 2.9 Nm, 3300 rpm, Hiperface","metaDescription":"BMI0703P26A three-phase servo motor, 2.9 Nm at 400V, 3300 rpm, IP65, active production, sourced to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":[],"specifications":{"Phase":"Three phase","Length":"11.8 in (300 mm)","Category":"US1PC5618287","Shaft end":"Untapped","EMC filter":"Integrated","Second shaft":"Without second shaft end","Shaft length":"1.2 in (30 mm)","Feedback type":"Absolute single turn SinCos Hiperface","Holding brake":"Without","Nominal speed":"3300 rpm 400 V three phase 1600 rpm 208 V three phase 3900 rpm 480 V three phase","Rotor inertia":"1.67 kg.cm²","Nominal torque":"25.7 lbf.in (2.9 N.m) 208 V three phase 23.9 lbf.in (2.7 N.m) 400 V three phase 20.4 lbf.in (2.3 N.m) 480 V three phase","Shaft diameter":"0.6 in (14 mm)","Torque constant":"1.41 N.m/A 68 °F (20 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Mounting Support":"International standard flange","Supply frequency":"50/60 Hz - 5...5 %","Back emf constant":"95.39 V/krpm 68 °F (20 °C)","Device short name":"BMI","Motor flange size":"2.8 in (70 mm)","Peak stall torque":"76.1 lbf.in (8.6 N.m) 208 V three phase 76.1 lbf.in (8.6 N.m) 400 V three phase 76.1 lbf.in (8.6 N.m) 480 V three phase","Stator inductance":"25.6 mH 68 °F (20 °C)","Stator resistance":"7.99 Ohm 68 °F (20 °C)","Maximum current Irms":"12.5 A 400 V, three phase 12.5 A 480 V, three phase 12.5 A 208 V, three phase","Nominal output power":"900 W 400 V three phase 900 W 480 V three phase 450 W 208 V three phase","Centring collar depth":"0.10 in (2.5 mm)","Electrical Connection":"Printed circuit board connector","Nbr. of units in pkg.":"1","Number of motor poles":"10","Supply voltage limits":"208...480 V","Maximum axial force Fa":"0.2 x Fr","Number of motor stacks":"3","Output current 3s peak":"6 A 400 V 3 s","Continuous stall torque":"30.09 lbf.in (3.4 N.m) 208...480 V three phase","IP Degree of Protection":"IP65","Maximum radial force Fr":"730 N 1000 rpm 580 N 2000 rpm 510 N 3000 rpm 460 N 4000 rpm 430 N 5000 rpm 400 N 6000 rpm","Mounting holes diameter":"0.2 in (5.5 mm)","Centring collar diameter":"2.4 in (60 mm)","Continuous stall current":"2 A","Maximum mechanical speed":"8000 rpm","Network frequency limits":"47.5...63 Hz","Number of mounting holes":"4","Continuous output current":"2 A 8 kHz","Product or Component Type":"Servo motor with power stage","Speed feedback resolution":"32768 points/turn","[Us] rated supply voltage":"208...480 V - 15...10 %","Distance shaft shoulder-flange":"0.10 in (2.5 mm)","Stator electrical time constant":"3.2 ms 68 °F (20 °C)","Circle diameter of the mounting holes":"3.0...3.2 in (75...82 mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1,620.00","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/3ef5ce39c60629570259145cf22570e6.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/BMI0703P26A/alternatives.json"},"ai":{"faq":[{"question":"What is the phase configuration of the BMI0703P26A?","answer":"It is a three-phase motor."},{"question":"What is the length of the BMI0703P26A?","answer":"The overall length is 300 mm (11.8 in)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/BMI0703P26A","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/BMI0703P26A when reusing this data.
