R911261906
The R911261906 (MDD115B-N-015-N2L-130GA0) is a high-performance servo motor developed by Bosch Rexroth Indramat, known for the fabrication of the MDD line of permanent magnet-excited motors. These motors support high feedrates while ensuring peak accuracy, which is particularly advantageous for rapid speed cutting tasks.
Specifically, the R911261906 (MDD115B-N-015-N2L-130GA0) model offers advanced features such as digital servo feedback to evaluate the motor's relative indirect position to an accuracy of ±0.5 angular minutes. It utilizes the optical measurement technique for precise execution and precludes the necessity for a supplementary encoder. The inbuilt data memory accelerates motor bootup by storing the motor type and control parameters. With a rated speed of 3000 RPM, it provides a top theoretical torque of 118.2 Nm and a rotor inertia of 172 x 10-4 kgm2. An IP 65 rated, black prime coated housing resists buildup, yellowing, weathering, lyes, and diluted acids while preventing penetration from solid materials and water sprays. Heat dissipation from the stator is achieved via conduction to the motor housing, enhancing its overload capacity. Cooled by natural convection and surface cooling, this motor is well-suited for handling high-demand loads and continuous start-stop applications with elevated repetition rates. Its electronic commutation complements its load-handling capabilities.
