Product Description:

Bosch Rexroth Indramat manufactures the MDD093B-N-040-N2M-110GA0 synchronous servo unit. It belongs to the MDD Synchronous Motors series and is intended for use with digital drive controllers in multi-axis automation lines. In these systems, the motor converts commanded electrical power into controlled rotary motion for positioning tools, conveyors, or auxiliary axes. Its synchronous operating principle supports accurate response to changing speed and torque commands during repeated start-stop cycles.

The motor develops a continuous standstill torque of 14.5 Nm, giving the axis energized holding capability at zero speed. Its rated operating speed reaches 4000 rpm, so fast indexing can be carried out without added gear stages in many machine layouts. A centering diameter of 110 mm provides the pilot fit between the housing and the machine frame for coaxial alignment under load. All power and feedback conductors exit on Side A, which can simplify cable routing where the connector must face a consistent direction. Position data is provided by an integrated multiturn absolute encoder, allowing the controller to retain revolution information after power cycling. The 093 frame with B length keeps the motor compact, and the aluminum housing helps transfer heat away from the stator.

The rotor uses standard balancing to reduce residual vibration during acceleration and steady operation. Velocity and position loops are closed with digital servo feedback, so the controller receives real-time motion data without an external encoder assembly. The design is supplied without a blocking brake, so any load-holding function must come from the drive or a separate mechanical device. A plain shaft with a shaft seal supports coupling to the driven load while helping limit contaminant entry at the output end. Only the drive side is machined because there is no shaft extension on side B. The single connector keeps the housing layout straightforward and leaves cabling concentrated at one end of the motor.
