R911250901
The R911250901 (MDD112D-N-020-N2L-130PB2) is a digital AC servomotor designed and manufactured by Bosch Rexroth Indramat. Equipped with a 40Nm blocking brake, it comes with both fixed and floating bearings and sports a brushless design. The size code of the device is 112. Optimized for high-precision applications, the motor even includes data storage capabilities in its feedback module where the motor parameters are stored. This high contouring accuracy motor can operate between 0°C to 45°C and integrates electronic commutation. The motor also provides an option to attach two types of flanges, and supports separate connectors for power and feedback cables.
The motor in standstill mode has a continuous torque of 38Nm when in natural convection cooling mode. Adhering to DIN 6885-1 specifications, it consists of a shaft with a keyway and can withstand high radial loads. The axial force of the device stands at 0.35 times the radial force. The motor also uses a holding brake to secure the output shaft at standstill and offers IP 65 degrees of protection. Additionally, it can operate at a height up to 1000m above sea level. The device's installation is flexible and can be done horizontally or vertically. It has a black coating for durability and a thermal time constant of 120 minutes.
