Product Description:

The MDD025B-N-100-N2K-040GR0 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a compact motor for digital drive controllers that provides rapid positioning and velocity control in automated machinery. With a standard housing and standard dynamic balancing, the unit suits installations where a small frame size and reliable high-speed operation are important. Its compact format also makes it practical for handling units, feed axes, and other machine sections where available mounting space is limited.

During stall conditions, the motor supplies a continuous torque of 0.60 Nm, allowing light loads to be held without overheating. Its rotor can reach a nominal speed of 10,000 rpm, so the drive can execute fast indexing moves when paired with a suitable inverter. Mechanical alignment is aided by a centering diameter of 40 mm, which matches the mounting pilot on corresponding gearboxes or brackets. The output uses a plain shaft that accepts friction-fit couplings, and a shaft seal is fitted to limit oil or coolant ingress at the bearing journal. The B motor length within size 025 keeps the unit short for dense machine layouts and supports installation in compact assemblies.

Electrical interfaces exit on the right side of the stator housing, and power plus feedback are routed through a keyed connector to simplify cable routing. Position data are transmitted by resolver feedback, which provides noise-tolerant analog signals, while an integrated absolute encoder supports direct digital position referencing at power-up. The motor is supplied without a blocking brake, so static holding must be provided by the drive or by external machine hardware. The lack of a side-B shaft extension helps keep the package compact and leaves more clearance for adjacent components in tightly arranged motion systems.
