Product Description:

The MDD115D-N-020-N2L-130PB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts drive commands into rotary motion for automated machinery that needs precise position and velocity control in continuous or intermittent duty cycles. The design is suited to closed-loop applications in which the controller continuously compares commanded motion with returned motor feedback. This helps the axis respond accurately during starts, stops, and speed changes during automated operation.

The unit reaches a nominal speed of 2000 rpm, allowing machine axes to operate at moderate rotational rates without overspeeding typical belt or screw transmissions. At standstill it can deliver 57.0 Nm of continuous torque, which is the maximum load it can hold indefinitely without overheating. Precise mechanical alignment is supported by a centering diameter of 130 mm, while all power and feedback conductors exit on Side B, which can simplify cable routing in compact machine layouts. Position data returns to the drive through digital servo feedback, allowing high-resolution commutation and real-time correction of motion errors. The drive end is machined with a keyway so torque can be transmitted through standard keyed couplings.

The motor is supplied without a blocking brake, so any static holding force must come from the drive or external clamps. Its mechanical envelope follows the D length code and the 115 frame size, which provides a longer active stack without changing the mounting footprint. The enclosure uses a standard housing and is dynamically balanced to a standard grade to help limit vibration in multi-axis assemblies. A molded connector provides the electrical interface, and a shaft seal helps keep lubricant in and contaminants out. The non-drive end remains solid to reduce added mass and inertia.
