The Bosch Rexroth R911251183 (MDD065B-N-040-N2L-095PA1) is a synchronous servo motor from the MDD product line, ideal for textiles, robotics, handling equipment, and printing machines. This high power density motor is perfectly suited to pressing, punching, and nibbling machine applications. Designed for high operating reliability, it features permanent magnets, electronic commutation, and an integral temperature sensor to prevent overload damage. The model offers an option for a 3Nm-rated electrically-released blocking brake which operates at 24V DC and draws 0.6A.
Weighing approximately 3.9kg for the motor and an additional 0.55kg for the brake, the total mass comes to 4.45kg. Motor winding resistance stands at 5.22 Ohms at 20°C with an inductance of 7.4 millihenry. The standard housing for the R911251183 (MDD065B-N-040-N2L-095PA1) motor supports surface cooling and natural convection, with a nominal speed of 4000 RPM. The motor allows for digital servo feedback and an IP65-rated protection offers dustproof and water-resistant capabilities.
