Product Description:

The MDD093B-N-040-N2M-110GR2 is a synchronous servo motor built by Bosch Rexroth Indramat and placed within the MDD Synchronous Motors series. Its standard housing encloses frame size 093 laminations, and the unit works with digital drive controllers to convert commanded current into rotary motion for indexing tables, cutters, and other axes. Housing, shaft end, and internal feedback components are assembled as a matched set so the motor can deliver mechanical power and positional data in compact machine frames.

A nominal speed of 4000 rpm indicates the rotor can maintain that velocity when driven by the matched controller and loaded to its rated torque. At standstill, the electromagnetic system sustains 14.5 Nm continuously, allowing the axis to hold tooling without drift. For power-off safety, the blocking brake applies 22 Nm of mechanical locking torque. Installation is centered by a 110 mm pilot diameter that fits Rexroth flange patterns. Rotor position is reported through digital servo feedback, and absolute position over multiple turns is provided by the integrated multiturn absolute encoder. Electrical power and feedback reach the unit through a single connector mounted on the end cap.

A plain shaft transmits torque without keyways, and the motor is supplied without a side-B shaft end so clamp hubs or shrink discs can be used where backlash must be minimized. Cable plugs are oriented for right-side connections, which can simplify harness routing in cabinets laid out with left-side airflow. Vibration is managed through standard balancing, which keeps residual forces within ISO limits and reduces bearing wear at high rotational speeds. A shaft seal limits lubricant egress, while the medium-length code B body balances inertia against continuous output capability without increasing overall mass.
