Product Description:

The MDD041C-N-100-N2K-050MB1 is a synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it translates drive commands into mechanical rotation for positioning or velocity-regulated axes in automated equipment. Its compact frame, keyed shaft end, and integrated brake make it suitable for light pick-and-place modules or spindle attachments that demand repeatable motion profiles. The motor also fits installations where space is limited and the axis must respond predictably during frequent start-stop operation.

The rotor can reach a nominal speed of 10000 rpm, giving the drive system a wide dynamic range when paired with high-frequency current control. At standstill the motor produces 2.05 Nm of continuous torque, so it can hold or index a load without overheating the stator windings. The front flange features a centering diameter of 50 mm, which aligns the housing to gearboxes or machine plates with minimal radial runout. Size code 041 indicates a stator diameter that keeps inertia low for rapid acceleration. Power and feedback leads exit on side B, which helps keep cable routing clear of nearby moving parts. A plug-in connector interface is used instead of flying leads, providing secure strain relief during vibration.

The blocking brake supplies 1.2 Nm of holding torque, so vertical axes can stay in position during drive shutdowns or emergency stops. Position data come from an integrated absolute encoder, enabling the controller to read the shaft angle immediately after power-up without homing cycles. For real-time speed loops, the motor also carries resolver feedback, delivering analog sine-cosine signals that remain resistant to electrical noise. This combination supports immediate position availability and stable closed-loop regulation during repeated motion cycles. Although the motor is shipped without a shaft seal, the keyed shaft and standard balancing allow direct coupling to pulleys or couplings when contamination risk is controlled by the surrounding machine enclosure.
