Product Description:

The MDD025A-N-100-N2K-040GF1 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers in compact rotary axes that require accurate position control in industrial automation. The motor converts electrical drive commands into mechanical rotation so that conveyors and pick-and-place axes can follow programmed motion profiles. Its synchronous design also supports repeatable response during short indexing moves and rapid direction changes. This makes it suitable for compact machines where fast starts, short moves, and accurate stopping are required.

The nominal operating speed reaches 10,000 rpm, allowing small mechanisms to attain rapid acceleration with minimal inertia. At standstill, the motor can deliver a continuous torque of 0.33 Nm, so closed-loop holding functions remain stable without excessive current draw. Rotor alignment to adjoining machine elements is supported by a centering diameter of 40 mm and standard dynamic balancing that helps reduce vibration during operation. Electrical and feedback conductors exit on the right side of the housing, which can simplify routing in compact enclosures. Position data is provided by an integrated absolute encoder, and the motor has a standard housing with length code A and no shaft extension on side B. The compact geometry is useful in small handling units where adjacent components limit available mounting space.

For load holding when power is removed, the motor includes a mechanical brake rated at 1.0 Nm. Power and signal connections are made through a connecting cable with a coupling unit, which allows the motor to be disconnected without removing the full cable run. Torque is transmitted through a plain shaft with a shaft seal, which helps limit contaminant ingress and lubricant escape. The motor uses a size 025 layout, and its standard housing keeps the package short while leaving no shaft extension on side B. The encoder and brake arrangement supports stable axis control during both motion and standstill.
