Product Description:

The MDD025B-N-100-N2G-040PA0 is a miniature synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Built for digital drive controllers, it serves in industrial automation systems that require precise velocity and position control on compact axes such as electronic cam followers, labelers, or pick-and-place heads. The motor couples directly to a drive controller, allowing the axis to accelerate quickly, maintain stable speed, and execute repeatable moves within short cycle times.

Its nominal rotational speed reaches 10000 rpm, giving the drive enough range for fast indexing tasks while maintaining synchronous operation. At standstill, the motor can supply 0.60 Nm of continuous torque, which is suitable for holding small loads without exceeding thermal limits. Mechanical fit is guided by a centering diameter of 40 mm, so the stator aligns concentrically with mounting flanges. Power and feedback cabling exit on Side A, and the single plug-in connector helps keep wiring compact inside tight enclosures. A standard housing and standard dynamic balancing help reduce vibration, and the motor is supplied without a blocking brake, so braking must be handled by the external drive or mechanism.

Position sensing relies on resolver feedback, providing continuous rotor angle information across the full speed range. The shaft has a keyway so torque can be transferred to pulleys or couplings without slip, and a shaft seal is fitted to help keep oil or dust out of the bearing chamber. The motor has a length code B, and the 025 frame designation keeps the cross-section small for dense multi-axis installations. A standard shaft end on the drive side, together with the absence of a shaft on side B, leaves the opposite face clear and supports compact coupling arrangements in lightweight machinery.
