Product Description:

The MDD093D-N-020-N2M-130GL2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers where closed-loop position and speed regulation are required on automated machine axes, pick-and-place tables, and material-handling stations. By combining permanent-magnet excitation with an integrated multi-turn absolute encoder, the unit converts electrical power from the drive into precisely controlled rotary motion for industrial automation tasks that demand accurate repeatability and quick acceleration. The integrated feedback arrangement also supports stable low-speed operation and repeatable positioning during frequent starts, stops, and direction changes.

At stall, the motor can deliver 24.0 Nm of continuous torque, allowing it to hold static loads without overheating when the shaft is blocked by process forces. During regular operation, its rated mechanical speed is 2000 rpm, which is the nominal operating speed for continuous use. A blocking brake built into the rear housing develops 22 Nm of holding torque, so vertical or suspended axes remain fixed after power is removed. The centering pilot of 130 mm aligns the motor concentrically on the mounting flange and helps minimize radial runout of the driven components. Position and velocity feedback are transmitted through digital servo feedback, which allows the controller to close high-resolution control loops without external encoders or tacho generators.

Standard dynamic balancing reduces vibration at speed and helps protect the bearings during repeated acceleration and deceleration. Cabling is routed through a connector on the left side of the stator housing, which can simplify cable routing in confined machine spaces. The motor has a plain shaft for use with couplings or pulleys without keyways, which reduces stress concentrations under cyclic reverse duty. A dedicated shaft seal surrounds the output journal so lubricants do not escape and contaminants do not enter the bearing chamber. The extended housing identified by the motor length code D provides additional active copper length, which supports the higher continuous torque rating available in this frame size.
