R911255850
The R911255850 (MDD093B-N-040-N2L-110PB0) is a high-precision synchronous servo motor in the MDD series by engineering powerhouse, Bosch Rexroth Indramat. Designed for automation systems, this servo motor is engineered for rapid response and cost-effectiveness when used in conjunction with Indramat digital drive controllers. Key features include a digital servo feedback system for accurately evaluating the motor’s relative indirect position using optical measurements. Its built-in data memory stores vital motor information that reduces startup time and allows for seamless drive controller adjustments without damage.
This MDD series servo motor employs a brushless design with permanently lubricated bearings boasting a nominal service life of 30,000 hours. The R911255850 (MDD093B-N-040-N2L-110PB0) combats heat buildup through natural convection and surface cooling. A thermal sensor housed in the stator windings ensures operational temperatures are monitored, preventing damage from thermal overload. Operating at a nominal speed of 4,000 RPM and housing a rotor with a moment of inertia of 29 x 10-4 kgm2, this servo motor is designed for efficiency and high dynamics. Its permanent magnets are of high-quality materials, creating a low inertia and an optimal torque-inertia ratio. For high repetition start-stop operations, the motor assures a high cyclical load capacity with the help of electronic commutation. Ensure optimal performance by maintaining an ambient temperature of 0oC to 45oC.
