MDD025B-N-100-N2G-040PR1
The MDD025B-N-100-N2G-040PR1 is a compact synchronous motor manufactured by Bosch Rexroth Indramat in the MDD Synchronous Motors series. It works with digital drive controllers to produce precise rotary motion for automated stations that need accurate speed and position control. Its size 025 and length code B give it a compact form factor for tight mounting spaces, while the standard housing and a shaft end without a side-B extension suit single-ended mechanical layouts. The compact body is useful in small indexing units and handling axes where installation space is limited but repeatable motion is still required.
The motor delivers a continuous standstill torque of 0.60 Nm, allowing an axis to hold light loads during dwell periods without excessive heating. The rotor reaches a nominal speed of 10000 rpm, which suits high-speed positioning tasks with short cycle times. A blocking brake with 1.0 Nm of holding torque secures the shaft when drive current is removed. Service connections exit on the right side, which can help keep cables clear of nearby machine elements. Mechanical centering uses a 40 mm pilot to align the motor accurately with the mating flange and reduce runout in coupled components.
Feedback is provided through resolver feedback, giving the drive real-time rotor angle data during acceleration and deceleration. This feedback method supports stable position information across a wide speed range and during rapid direction changes. Torque is transmitted through a keyway shaft, which suits keyed hubs in applications with repeated reversals. The motor also uses a shaft seal to limit contamination from fine dust or lubricant mist. Its rotor is balanced to a standard balance grade, which helps keep vibration low at high speed, and an integral connector with the standard housing simplifies electrical connection in compact machine assemblies.
