The Bosch Rexroth R911256162 (MDD115A-N-030-N2L-130PB1) is a compact, synchronous servo motor belonging to the MDD series, perfect for dynamical use in roller feeds, pressing, and tool changing devices. It features high power density and delivers superior contouring accuracy even at high-speed ranges. Notable characteristics include high overload capacity, derived from efficient heat conduction from the stator windings to the motor housing and a high cyclic load capacity making it ideal for start-stop operations with high repetition rates. The maintenance-free design incorporates electronic commutation and a lifelong lubricated bearing that has a nominal life of 30,000 operating hours. The motor is also structured to take on high radial loads. It utilises natural convection and surface cooling, with a thermal sensor to avoid thermal overload. The completely sealed housing offers IP 65 protection, allowing safe operation in harsh environments. The motor has a black prime coat, a nominal speed of 3000 rpm, and a digital servo feedback encoder system.
