This product is part of the Lexium 28 range, an offer of motion servo drives for machines from 0.05 to 4.5kW. The brushless servo motor features a high moment of inertia with maximum mechanical speed of 5000RPM and IP65 parallel keyed shaft without holding brake. It is equipped with a 20bit single-turn absolute encoder, optimized in terms of speed of rotation (3000RPM). It is a second generation servo motors suitable for a wide variety of applications due to the different levels of motor inertia offered. It has a rated supply voltage of 220V, a continuous stall current of 2.19A and a continuous power of 400W. The shaft dimensions are 14mm (Diameter) x 30mm (Length). It is furnished with free lead for electrical connection. It is an IP50 (IM V3) and IP65 (IM B5, IM V1) rated product. Its dimensions are 129mm (Length) x 60mm (Width), centring collar dimensions are 5.5mm (Depth) x 50mm (Diameter) with 70mm circle diameter of the mounting hole. It weighs 1.45kg. This product is compatible with Lexium 28 and Lexium 26D servo drives. It supports Asian standard 60mm flange mount with a natural convection cooling system. Lexium 28 and Lexium BCH2, the optimized servo bundle for all motion control solutions are cost effective, energy efficient and embedded safety. Lexium 28 servo drives and Lexium BCH2 servo motors, optimized servo bundles for compact machines.
