Product details

Overview

The BMI1003P21A is a Schneider servo motor with 10 poles, three-phase operation, and a power output of 1000 W at 4 A continuous current. Rated IP65, the motor accepts a 480 V supply and uses natural convection cooling.

The 4 A continuous current rating defines the sustained load the motor can drive; the 1000 W power output matches applications requiring moderate torque at speed. Absolute single-turn SinCos Hiperface feedback provides position resolution of 131072 points per turn, enabling precise positioning without a homing cycle on power-up. The torque rating of 75.2 lbf.in (8.5 N.m) at 208–480 V three-phase gives the sizing basis for direct-drive or geared loads.
