Product details

Integration notes

The BMI0703P21A is a three-phase servo motor rated 900W at 400 V three-phase, with IP65 protection and an integrated EMC filter for direct connection to a drive without an external filter. Absolute single-turn Hiperface feedback provides position at power-up, eliminating homing routines. The untapped shaft measures 14 mm diameter, 30 mm long, mounted on a 70 mm flange with a 60 mm centring collar. Nominal torque at 400 V is 2.7 N·m, with a peak stall torque of 8.6 N·m across the supply range. Continuous stall torque sits at 3.4 N·m. Speed reaches 3300 rpm at 400 V; derate to 1600 rpm at 208 V.

Frequently asked questions
