MDD025C-N-100-N2K-040FC1
The MDD025C-N-100-N2K-040FC1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified for use with digital drive controllers, it serves as the rotary actuator in compact axes where high positioning accuracy and fast speed changes are required. By converting drive current into precise mechanical rotation, the unit supports pick-and-place modules, laboratory machines, and small packaging stations. This type of motor is commonly used where compact dimensions and responsive motion are more important than high torque reserve. Because it is intended for compact axes, it suits machinery that needs accurate starts, stops, and reversals without a large motor footprint.
The motor delivers a continuous standstill torque of 0.90 Nm, allowing it to hold static loads while the drive remains energized. Its rated mechanical speed reaches 10000 rpm, which supports high cycle rates in fast-moving applications. A centering diameter of 40 mm provides the pilot fit that aligns the stator housing to the mounting surface. This centering feature helps keep shaft alignment consistent when the motor is mounted to a machine plate or gearbox adapter. Power and feedback leads exit on side A, which can simplify cable routing when the machine layout is built around that orientation. The motor size is 025, and it has a standard housing, a plain shaft, and no shaft seal for use in protected environments.
The integrated blocking brake provides 1.0 Nm of holding torque, so vertical or inclined axes can remain stationary when power is removed. Length code C is the longest rotor stack offered for this frame and keeps the same mounting interface. Position data comes from an integrated absolute encoder, while commutation data is supplied through resolver feedback to resist electrical noise. The separate position and commutation channels support stable control during startup, reversal, and low-speed operation. Connection to the drive uses a coupling-type cable set, and the shaft is single-ended without a side-B extension.
