The Bosch Rexroth MPN R911262320 (MDD065B-N-040-N2M-095PA1) is a digital AC motor engineered for nibbling machine applications. It features a compact, lightweight construction without a blocking brake and a total mass of 3.2 kg. The motor incorporates a shock-damped mount, dual surface cooling methods, and offers straight or angled connectors for feedback integration. Compliant with IEC 721-1, it supports 40 m/s² reference acceleration along the longitudinal axis. The design ensures high synchronism and cyclic load capacity due to high-resolution feedback, supporting precise start-stop operations. The motor uses a standard INS 252 power connector, supports up to 75 m cable length, and requires closed-circuit operation for the blocking brake. Key mechanical specifications include a 0.43 Nm torque constant, a 5.22 Ohm winding resistance at 20°C, standard housing and balancing, 1.5 Nm continuous torque at standstill, 4000 min⁻¹ nominal speed, 95 mm centering diameter, shaft with keyway and shaft seal, integrated multiturn absolute encoder, and digital servo feedback (DSF). Bearings are floating on side A and fixed on side B; impacts and heavy loads may cause damage. Steam cleaning is not recommended as it may result in coating peeling.
