Product Description:

The MDD025B-N-100-N2G-040GL0 is a compact servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commands from a servo amplifier into precise rotary motion for small actuators, tool heads, and indexing stations on automated lines. When paired with compatible drive and feedback hardware, the unit supports tight velocity loops and position control required in modern industrial automation.

A centering pilot of 40 mm locates the flange concentrically to linked gear stages, while standard balancing keeps vibration within limits at rated speed. The electrical and feedback connectors are routed on the left side and use a single connector style plug, simplifying cable runs in compact enclosures. During static operation, it sustains a continuous torque of 0.60 Nm, and dynamic tasks can be completed up to a nominal shaft velocity of 10000 rpm. These values suit lightweight loads that need rapid acceleration without exceeding thermal limits. Housing and shaft sealing elements follow the standard design code used in the MDD family, so mounting hardware and sealing arrangements remain consistent across frame sizes.

Additional configuration codes further describe the motor layout. The frame is identified as motor size 025, and the B-length stator section increases copper fill compared with shorter variants of the same diameter. Torque is transferred through a plain shaft, and a shaft seal at the exit point helps block lubricant and dust ingress. Position data comes from resolver feedback, giving analog sine-cosine signals to the drive for high-speed interpolation. Because the unit is supplied without a blocking brake, stationary holding must be handled by the controller or external mechanics. The motor uses a standard shaft on side A with no extension on side B, and all mechanical tolerances follow the standard housing design used for this family.
