Servo motor essentials
The BMI0703P07A is a three-phase servo motor with an integrated EMC filter, rated for 208–480 V supply and 50/60 Hz line frequency. It delivers nominal output power up to 900 W at 400/480 V and 450 W at 208 V, with a nominal speed of 3300 rpm at 400 V (1600 rpm at 208 V, 3900 rpm at 480 V). Feedback comes from an absolute multiturn SinCos Hiperface encoder, providing position data without a homing sequence on power-up. The motor is cooled by natural convection and carries shaft IP54 / housing IP65 protection.
Mechanical interface
The motor uses an international standard flange (70 mm flange size) with a 14 mm shaft diameter, 30 mm shaft length, and untapped shaft end. Centering collar diameter is 60 mm with 2.5 mm depth; four mounting holes of 5.5 mm diameter accept standard bolts. Total length is 300 mm. No holding brake or second shaft end is fitted. Maximum permissible radial force decreases with speed: 730 N at 1000 rpm, 580 N at 2000 rpm, 510 N at 3000 rpm, 460 N at 4000 rpm, 430 N at 5000 rpm, and 400 N at 6000 rpm. Axial force is limited to 0.2 × the radial force at a given speed.
Torque and current characteristics
Continuous stall torque is 3.4 N·m across the 208–480 V range, with a continuous stall current of 2 A. Peak stall torque reaches 8.6 N·m, and the maximum rms current is 12.5 A (3 s peak current: 6 A at 400 V). Nominal torque varies by voltage: 2.9 N·m at 208 V, 2.7 N·m at 400 V, and 2.3 N·m at 480 V.
The lifecycle stage for this motor is listed as current. No official manufacturer cross-reference or successor is documented in this listing. Verification of fit to your application should include a review of the electrical connection (printed circuit board connector) and mechanical interface data above.
