Schneider Electric BCH1303N12A1C BCH Series Servo Motor — 1.5 kW, 220 VAC Single-Phase, 3000 rpm Max, Keyed Shaft 22 mm (8 mm Key), 20-bit Incremental Encoder, No Brake, IP40

The Schneider Electric BCH1303N12A1C is a BCH series industrial servo motor designed for high-performance closed-loop motion applications. This variant delivers 1.5 kW continuous power from a 220 V single-phase supply, features a keyed shaft (22 mm diameter, 8 mm key), a 20-bit incremental encoder for precise feedback, and is supplied without an integrated holding brake. Note: this model was discontinued 31 Dec 2018 with end-of-service 30 Jun 2022 and has no direct replacement—contact Schneider Electric customer care for support.
