R911254893
The Bosch Rexroth Indramat R911254893 (MDD112D-N-040-N2L-130PB0) is an MDD servo motor particularly designed for high precision operations that demand outstanding synchronism, such as in grinding machines. It is equipped with a brushless design and a lifetime-lubricated bearing, boasting a nominal service life of 30,000 operating hours, making it capable of maintenance-free operation. The compact build results in a high power-to-weight ratio while its built-in thermal sensor aids in excessive temperature monitoring to prevent potential overload hazards. It exhibits high overload capacity because of the effective heat elimination from its windings to the outer walls of its casing.
This motor is encased in black prime varnish, ensuring resistance against weathering, yellowing, lye penetration, and chalky buildup. It maintains a nominal speed of 4,000 RPM and features a centering diameter of 130mm. An integral shaft with a keyway, as per DIN 6885, and a sealing ring assure form-fitting torque transmission. Its dust-proof, touch-proof sealed housing offers an IP 65 rating in accordance with EN 60529, providing resistance against multidirectional water jet sprays and shocks. The motor incorporates a digital servo feedback system, allowing for precision positioning via optical measurement.
