Product details

Overview

The BSH1403T31A1P is a Schneider Lexium 32 BSH-frame servo motor rated 27.8 N.m continuous torque at 4800 rpm, 5 poles, three-phase, IP65 sealed. It carries a single-turn SinCos Hiperface encoder resolving 131072 points per turn, a keyed shaft, and no holding brake — suited for applications where the load holds position without a brake or an external brake is fitted.

Compared to the BSH1403T31F1P, the BSH1403T31A1P omits the holding brake (0.0 kg.cm² brake inertia vs 5.5 kg.cm²) and uses straight connectors rather than rotatable right-angled connectors — the BSH1403T31F1P is the braked variant for vertical-axis or safety-hold duty.
