Product Description:

The MDD025B-N-100-N2K-040MR1 is a compact servo motor built by Bosch Rexroth Indramat in the MDD Synchronous Motors series, intended to drive low-inertia machine axes that rely on digital controllers for rapid positioning. By combining a permanent-magnet rotor with an integrated absolute encoder, the motor provides closed-loop feedback so that automated packaging heads, labeling stations, or small gantries can achieve repeatable speed and position profiles.

The motor produces a continuous standstill torque of 0.60 Nm, giving steady holding force against process loads while remaining within its thermal limits. When acceleration peaks are required, a blocking brake rated for 1.0 Nm locks the shaft to prevent back-driving during power loss or emergency stops. High throughput is supported by a nominal speed of 10000 min⁻¹, enabling short cycle times in indexing tables. Servo accuracy is helped by resolver feedback, which supplies analog sine-cosine position signals that the drive converts into high-resolution counts. Mechanical alignment inside a mounting flange is simplified by a 40 mm centering diameter that matches industry-standard pilot registers.

Additional construction details reinforce the dynamic profile. A keyway shaft transmits torque without slip, and all power and feedback leads exit on the right side to keep wiring orderly in multi-axis racks. The B-length stator, identified by motor length code B, offers more copper than the shorter variant, improving short-term overload capacity without increasing width. To minimize drag, the housing is supplied without a shaft seal; this choice is acceptable when the motor is placed in clean, cabinet-mounted environments where liquid ingress is not expected.
