Product Description:

The MDD041C-N-100-N2G-050GA0 is a synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for pairing with digital drive controllers, where its compact 041 frame size and C-length stator support high-speed positioning in packaging, pick-and-place, or light machining axes. It is supplied as a ready-to-mount unit for servo applications that need accurate response and repeatable motion. Its compact format helps it fit moving assemblies where low installed mass and short cycle times are important.

Mechanical attachment to the machine frame is centered by a 50 mm pilot, and rotor mass is kept within normal limits through standard balancing. Power, feedback, and ground conductors exit on Side A, and a keyed circular connector supports cable attachment. The housing uses the standard MDD fin pattern for natural air convection, and the motor is supplied with a shaft seal to reduce lubricant migration toward the bearings. Resolver electronics furnish resolver feedback so the drive receives rotor angle data during rapid acceleration. Length code C sets the overall stack height, and the shaft uses the standard single extension, leaving side B closed for better ingress protection.

The electromagnetic section is rated for a continuous standstill torque of 2.05 Nm, allowing stable force delivery when the axis holds position. Under rated excitation, the rotor reaches a nominal speed of 10,000 rpm, which supports short cycle times in high-throughput cells. The design is supplied without a blocking brake, so static holding must be provided by the drive or by external clamping devices. A plain shaft interface keeps torsional compliance low and avoids key stress concentrations. Standard housing geometry and balancing also help maintain vibration levels suitable for precision automation.
