It delivers 700 W nominal at 230 V single phase and 400 W at 115 V, with corresponding nominal torques of 2.9 N·m and 2.2 N·m. Continuous stall torque is 3.4 N·m across the voltage range. ## Feedback and cabling Feedback is provided by a Hiperface absolute multiturn SinCos encoder. This single-cable digital protocol carries both power and feedback on a standard connector — no separate encoder cable needed. The motor ships with a printed circuit board connector for electrical termination. The shaft is 14 mm diameter, 30 mm long, untapped, and without a second shaft end. The flange is an international standard 70 mm square with a 60 mm pilot diameter and 5.5 mm mounting holes. ## Duty and thermal management Integrated EMC filter reduces conducted emissions to the supply side, simplifying panel compliance. No external line filter is required for standard installations. Cooling is natural convection — no fan or forced air needed, but the motor must be mounted with adequate free air circulation around the fins. Stator resistance is 2.58 Ω and inductance 2.28 mH at 20 °C. The torque constant is 0.81 N·m/A and back EMF constant 54.44 V/krpm. Continuous stall current is 3.5 A; peak current is 10.5 A for 3 seconds at 230 V. ## Mechanical limits Maximum radial force is speed-dependent: 730 N at 1000 rpm declining to 400 N at 6000 rpm. Axial force limit is 20% of the radial force at the same speed.","metaTitle":"BMI0703T27A Servo Motor, 700W, 2.9 Nm, IP65, Hiperface","metaDescription":"BMI0703T27A single-phase servo motor: 230V/115V, 700/400W, 2.9/2.2 Nm, IP65, Hiperface multiturn absolute encoder, integrated EMC filter.
