MDD025B-N-100-N2G-040GB1
The MDD025B-N-100-N2G-040GB1 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is intended to drive light mechanical loads and provide finely graded velocity and position control in industrial automation cells, pick-and-place modules, and laboratory handling equipment. Because the shaft is present only on the drive side, surrounding instruments can be placed close to the rear housing without interference.
At the electrical end, the unit delivers a continuous standstill torque of 0.60 Nm, which provides stable holding force without overheating. When motion is commanded, it can reach a nominal shaft speed of 10000 rpm, which suits high-speed indexing tasks. All power and feedback cables exit at the rear because the connection hardware is mounted on side B and uses a keyed connector interface that simplifies removal during maintenance. A blocking brake rated at 1.0 Nm locks the rotor whenever the drive is disabled, helping prevent back-driving in vertical or precision stop positions. The motor uses standard dynamic balancing, and the compact 025 frame with length code B keeps mass low while the standard housing protects the windings.
Feedback data are returned via resolver feedback, giving rotor angle information for real-time current loops. The stainless-steel output uses a plain shaft profile, so torque is transferred through external clamping hubs, and the motor is delivered with a shaft seal that blocks lubricant or coolant ingress along the journal. Precise frame alignment is aided by a centering pilot of 40 mm, which matches standardized motor flanges and reduces lateral runout. This arrangement supports rapid commutation even at the specified maximum speed.
