Product Description:

The MDD090A-N-020-N2M-110GR1 is a three-phase permanent-magnet servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts command currents into controlled rotary motion while returning position data to the servo amplifier. The motor is intended for industrial automation axes that demand accurate speed regulation, coordinated multi-axis positioning, and repeatable duty cycles in packaging, printing, and material-handling machinery. Its synchronous design supports stable closed-loop motion and responsive torque production during frequent start-and-stop operation.

This model reaches a nominal rotational speed of 2000 rpm, allowing moderate throughput on axes where torque reserve is more critical than top speed. At standstill it can supply 3.7 Nm of continuous torque, so the drive can hold static loads without overheating. The centering shoulder diameter of 110 mm aligns the housing in precision machine frames and helps keep radial runout low. Position data are delivered by an integrated multiturn absolute encoder, and derivative velocity signals are passed to the controller through digital servo feedback (DSF). Electrical power, feedback, and brake leads exit on the right side, which helps keep cable routing orderly in compact machine layouts.

A factory-installed blocking brake secures the rotor with 6.5 Nm of holding torque, preventing back-driving on vertical or suspended loads when power is removed. Mechanical output is transmitted through a plain shaft, and a shaft seal at the front bearing helps keep dust and coolant away from the stator cavity. The motor’s hybrid signal and power link uses a keyed front-face connector, which keeps the connection point accessible when mounting space is limited. Standard dynamic balancing and the compact housing reduce vibration, while size code 090 and length code A shorten the body and eliminate a side-B shaft end for installations with restricted depth.
