IM B5 flange with V1 and V3 mounting orientations means the same motor drops onto either a shaft-down or shaft-up mounting pattern without re-machining the bracket; the power/signal connector exits toward the NDE, so cable routing clears the encoder cover and stays out of the coupling.","metaTitle":"Siemens 1FK7033-7AK71-3AG5 Servo Motor, 3 Nm, 6000 rpm","metaDescription":"Siemens 1FK7033-7AK71-3AG5 SIMOTICS S 1FK7 servo motor, 3 Nm, 6000 rpm, sin/cos encoder, EOL.
