MDD025B-N-100-N2G-040PF0
The MDD025B-N-100-N2G-040PF0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor intended for digital drive controllers, it supplies rapid rotary motion for light, high-cycle automation axes found in assembly handling, small gantries, and labeling stations. Its compact 025 frame and resolver-based feedback allow motion processors to achieve precise velocity and position loops while maintaining a modest installed footprint. The motor is suited to compact servo applications that need fast response and stable closed-loop control.
Under continuous stall conditions, the rotor can develop 0.60 Nm of torque, giving reliable holding force for small inertial loads without overheating. During operation, it reaches a nominal speed of 10000 rpm, so gear stages or direct-drive spindles can run at application-specific surface velocities. Accurate mechanical registration is simplified by the centering diameter of 40 mm, which fits standard mounting flanges. Power is transmitted through a shaft with a keyway, and the connections exit on the right side of the housing so cable routing stays clear of linear guides or frame members. This layout helps when the motor is installed in tight spaces with limited cable clearance. The unit follows the standard dynamic balancing class, minimizing residual vibration at high rotational speeds.
Control integration is accomplished with resolver feedback, which returns rotor angle and speed signals to the drive without the light-sensitive components used in optical encoders. Motor power leads are supplied through a connecting cable with a coupling unit, reducing installation effort inside tight cabinets. For applications that rely on external mechanical restraints, the rotor is supplied without a blocking brake, eliminating brake-release delays during rapid index cycles. Contaminant ingress at the output end is limited by a shaft seal, allowing the standard housing to tolerate coolant mist and fine dust while retaining factory lubrication. The motor is commonly used on small axes where limited installation space and short cycle times are important.
