Product Description:

The MDD025B-N-100-N2K-040GL1 is a compact synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts drive current into tightly regulated rotary motion for pick-and-place modules, small conveyors, and other high-cycle automation axes. The B-length variant and 025 frame allow installation where space and weight are limited. Its compact size also suits short-stroke handling systems and other layouts where moving mass must be kept low.

During continuous operation at standstill, the rotor can deliver 0.60 Nm of torque, which is suitable for light mechanical loads that still require firm holding force. Under rated excitation, it can reach 10000 rpm, enabling high surface speeds on small-diameter tooling and other fast-moving components. Alignment to the machine frame is simplified by a 40 mm centering diameter, which helps the motor seat accurately against the mating surface. Electrical and feedback conductors exit on the left side through a sealed connector, which helps streamline cable routing inside compact panels. Rotor position is returned through resolver feedback, which tolerates vibration and temperature variation while giving the drive a reliable commutation signal. A standard housing encloses these elements and protects the internal stator windings during operation.

The motor is built with a blocking brake that supplies 1.0 Nm of torque to hold the shaft when power is removed. Rotation is transmitted through a plain shaft, and a durable shaft seal limits oil or coolant ingress around the journal. Because the model omits a side-B extension, it occupies less axial space at the load end. This arrangement is useful on compact axes where the driven element sits close to the motor face and extra shaft length is unnecessary.
