R911255850 (MDD093B-N-040-N2L-110PB0)

Description

The Bosch Rexroth R911255850 (MDD093B-N-040-N2L-110PB0) is a high-precision servo motor from the acclaimed MDD series. This motor utilizes an optical measurement encoded feedback system, boasting an accuracy of ±0.5 angular minutes. Thanks to its stored motor information, startup time is significantly reduced, minimizing the risk of damage to the drive controller. Designed with sustained efficiency in mind, it has a brushless setup and lubricated-for-life bearings, anticipated to last up to 30,000 operational hours. The motor's temperature is regulated via natural convection and surface cooling, with an in-built thermal sensor in the stator windings for overload protection. It operates at a nominal speed of 4000 RPM with a rotor inertial moment of 29 x 10-4 kgm2. Its high-grade permanent magnets ensure low inertia, enabling a high torque-to-inertia ratio. For optimal performance, this motor should operate within an ambient temperature range of 0oC to 45oC.
