Product Description:

The MDD041C-N-100-N2G-050PB0 is a synchronous servo motor in the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is intended for use with compatible digital drive controllers to deliver high-speed closed-loop rotary motion on compact axes in automated machinery. By converting three-phase electrical power into controlled torque, the unit supports positioning, indexing, and speed-control tasks in conveyors, pick-and-place heads, and light spindle applications. Its compact format suits machines that need repeatable motion without the larger footprint of a higher-frame motor.

Mechanically, the motor seats against a centering pilot of 50 mm, which helps keep the stator concentric with the driven load and reduces runout at the coupling. Service wiring exits on side B, which is useful when the cable track is routed behind the axis. Under steady excitation, the electromagnetic package sustains 2.05 Nm of standstill torque, so holding force is supplied by drive current rather than by a mechanical brake. The rotor reaches a nominal speed of 10000 rpm, which supports fast cycling and high surface speed in compact spindle duties. All power, feedback, and protective earth conductors terminate on a single connector, which keeps the interface compact and reduces the number of separate cable entries.

The motor is supplied without a blocking brake, so loads that must remain fixed during power loss need external holding torque or a separate mechanical device. Position data is returned through resolver feedback, which provides a robust signal for closed-loop control in electrically noisy environments. The output shaft uses a keyway for positive torque transmission, and the motor is fitted with a shaft seal to help keep contamination away from internal bearing areas. The 041 frame with length code C also keeps the package compact for axes that reverse quickly and have limited installation space.
