The BMI0702T21A is a 10-pole single-phase servo motor in the Rexroth BMI family. Rated 700 W at 230 V single-phase, it delivers 2.2 Nm nominal torque (1.7 Nm at 115 V) and spins to 4000 rpm. The integrated SinCos Hiperface absolute encoder provides single-turn position feedback – no commutation alignment needed on power-up. Natural convection cooling means no fan connection; keep clear airflow around the IP65 enclosure.
Single phase.
