MDD025C-N-100-N2K-040MB0
The MDD025C-N-100-N2K-040MB0 is a compact synchronous servo motor engineered by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies precise shaft power to machine axes that require high dynamic response. In automated equipment, it converts controlled electrical input into accurate rotary movement for rapid starts, stops, and position changes. The size 025 frame with C motor length places the unit at the smaller end of the series, making it suitable for pick-and-place heads, lightweight gantries, and indexing tables in automated assembly lines.
The motor delivers a continuous standstill torque of 0.90 Nm, allowing the axis to hold position without overheating when no motion is commanded. Its rated mechanical speed reaches 10,000 rpm, so the drive can support fast accelerations in short-stroke duties. Power and feedback conductors exit on Side B, which can simplify cable routing when the flange faces forward. Position information is provided by an integrated absolute encoder, which eliminates the need for homing after power cycles and supports repeatable startup behavior. Because the unit is supplied without a blocking brake, external holding must be provided when load retention is required with power removed.
Mechanical integration is supported by a 40 mm centering diameter that aligns the standard housing to precision machine frames. Resolver signals are also available through the secondary channel as resolver feedback, giving the drive a low-latency position reference in addition to the primary encoder channel. The single-ended shaft uses a keyway and is supplied without a shaft seal, so the mounting area should be kept free of coolant spray. This shaft arrangement is intended for coupled mechanical outputs rather than wet mounting zones. Electrical hookup uses a circular connector, and the motor is balanced to the standard grade to help control vibration levels during operation.
