Product Description:

The MDD090B-N-020-N2M-110GB2 is a servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers and provides controlled rotary motion for axes that require accurate positioning in industrial automation equipment. The housing, feedback system, and mechanical interfaces match compatible Indramat drive components, so the motor can connect to the drive platform without external adapters. This layout supports coordinated motion tasks where stable speed control and repeatable positioning are required.

At standstill, the motor delivers a continuous torque of 7.2 Nm, providing holding force while the axis remains energized. During operation, it reaches a nominal speed of 2000 rpm, which gives the drive a practical continuous operating point for general motion duty. A built-in blocking brake supplies 11.0 Nm of static torque to hold the shaft after shutdown. Position data is provided by an integrated multi-turn absolute encoder, which retains position counts through power loss. The motor uses a 110 mm pilot diameter for accurate centering, and all conductors exit on side B, which helps keep cable routing contained at the rear of the housing.

The motor uses a connector interface instead of loose leads, giving the housing a secure electrical connection point. Feedback is transmitted through Digital servo feedback (DSF), allowing the controller to receive high-resolution position information through a matched feedback channel. The output uses a plain shaft with an integral shaft seal, which supports direct coupling while helping limit contamination at the bearing area. Standard balancing is used, and the aluminum housing follows the standard geometry for this motor type. The motor has size 090 with length code B, which keeps the package moderate in mass and inertia. The shaft end is provided only on the drive side, which reduces overhung load on auxiliary components.
