Product Description:

The MDD041C-N-100-N2K-050PA1 is a servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers in high-speed automation where compact rotary axes are required. Size 041 and length code C give the unit a short body that fits light-duty mechanical frames, while the standard housing and standard dynamic balancing support direct mounting in compact assemblies. Its compact format suits handling units, small indexing devices, and other axes where fast response matters. The integrated feedback system supports closed-loop position monitoring during operation.

The motor’s nominal speed reaches 10,000 rpm, supporting rapid positioning and short cycle times. At standstill it can deliver a continuous torque of 2.05 Nm, so the drive can maintain holding torque without excessive thermal stress. A centering diameter of 50 mm locates the flange precisely on companion gearboxes or adapter plates, which helps reduce radial misalignment. Power and feedback conductors exit on Side A, which simplifies cable routing when surrounding machine parts limit access from the opposite face. The plug-in connector interface simplifies cable attachment and helps prevent wiring errors. The motor uses resolver feedback, which provides analog position signals that tolerate electrical noise and remain stable at high rotational speed.

A blocking brake rated at 1.2 Nm secures vertical axes or index tables when the drive is disabled. The output shaft uses a keyway, allowing positive torque transfer into couplings or pulleys, and the standard shaft end is provided only on the drive side to keep overhung mass low. A dedicated shaft seal protects the front bearing area against coolant splash and fine dust. This arrangement helps keep contamination away from the shaft opening and supports longer bearing service life in enclosed industrial machinery.
