Product Description:

The MDD093D-N-020-N2M-110PA0 is a permanent-magnet synchronous motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts commanded current into precisely regulated mechanical motion for axes in machine tools, printing machinery, and handling equipment. In closed-loop service, the motor supports repeatable torque and speed so positioning, velocity, and tension remain stable as load conditions change. Its permanent-magnet design also supports responsive servo operation without adding unnecessary bulk to the drive system.

This model supplies a continuous standstill torque of 24.0 Nm, allowing it to hold or accelerate moderate inertias without excessive thermal stress. Under rated excitation, it reaches a nominal speed of 2000 rpm, which suits applications that favor smooth, quiet rotation over very high spindle speed. The motor uses frame size 093 with length code D, giving a housing size suited to medium-duty servo axes. A centering diameter of 110 mm helps align the motor accurately with the mating machine surface, which can reduce coupling misalignment and unwanted vibration during operation.

Power and feedback connections exit on side A of the housing, which can simplify cable routing where space is limited. Position data is provided by an integrated multi-turn absolute encoder, and the motor uses Digital servo feedback (DSF) so the controller can maintain closed-loop motion without relying on separate external sensing hardware. The output shaft has a standard keyway and comes with a shaft seal, helping protect the front bearing area from coolant and dust. The motor does not include a blocking brake, so any required holding function must be supplied by the driven mechanism or by commanded drive torque when the axis is stopped.
