Product Description:

The MDD041C-N-100-N2G-050MB0 is a synchronous servo motor built by Bosch Rexroth Indramat for use with digital drive controllers in the MDD Synchronous Motors series. As a compact rotary actuator, the unit converts drive current into controlled mechanical motion, making it suitable for positioning axes, pick-and-place heads, and other cyclic automation tasks where tight speed regulation is required. Its synchronous design allows the paired controller to maintain precise motion during rapid starts, stops, and short indexing moves.

At its nominal operating point, the motor reaches 10000 rpm, a high rated speed that supports rapid cycle times in lightweight mechanical stages. Continuous stall torque is 2.05 Nm, which indicates the steady torque that can be held without overheating when the rotor is stopped. A centering collar diameter of 50 mm provides the pilot fit that aligns the housing with machine frames, while standard dynamic balancing helps keep vibration within normal limits. Power and feedback leads exit on side B, which can simplify cable routing when the shaft faces the operator. The housing uses the 041 frame size, and the C length code adds active stack height without changing the mounting footprint.

Mechanical coupling is handled by a keyway shaft that transmits torque into pulleys or gears without relying on friction alone. The single-ended shaft omits a side-B extension, which helps reduce total length in compact installations. Position data is supplied through resolver feedback, permitting coarse absolute position detection and stable speed loops in harsh electrical environments. A molded connector carries all windings and sensor conductors, reducing manual termination work. The unit is supplied without a blocking brake, so motion must be held by the drive or an external clamp. The absence of a shaft seal makes the motor better suited for clean, dry enclosures where fluid ingress is not expected.
