Product Description:
The MDD115A-L-020-N2L-130GA1 is a synchronous servo motor engineered by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts drive output into rotational motion for positioning or velocity tasks in industrial handling equipment and machine tools. The design packages the stator, rotor, and integrated blocking brake in a frame that interfaces with the controller through a detachable connector, supporting straightforward installation in modular automation cells.
The motor delivers a continuous standstill torque of 28.0 Nm, giving machines stable holding force during low-speed processes such as threading or indexing. When motion is commanded, the rotor can reach a nominal speed of 2000 rpm, which matches drive parameters for medium-inertia axes that require moderate throughput without excess heat. Heat is removed through surface cooling, so cabinet air does not need to carry the full waste-heat load. The electrical and feedback leads exit on Side A, reducing cable loops when the motor is installed against bulkheads. The motor uses frame size 115, with bolt pattern, pilot diameter, and shaft height matched to that housing class.
For dynamic stops, the integrated blocking brake supplies 45.0 Nm of torque, which can help hold or stop vertical axes without external clamping devices. Accurate position verification is supplied by the built-in digital servo feedback, which sends rotor data to the drive for closed-loop control. A centering flange of 130 mm helps align the motor with gearboxes while maintaining concentricity under load. Protection against lubricant migration is provided by a fitted shaft seal, and the plain shaft uses a standard single-ended design that transmits torque through couplings without keyways. Additional build details include standard balancing for low vibration, a motor length code A body, and a connector interface that keeps cable attachment straightforward.
