MDD025A-N-100-N2G-040GD1
The MDD025A-N-100-N2G-040GD1 is a synchronous servo motor built by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. It is intended for use with digital drive controllers and is applied where rapid, closed-loop rotary motion is required in compact industrial handling modules. A resolver mounted on the rotor supplies real-time angular data to the accompanying drive, allowing the controller to maintain programmed velocity profiles and positioning tolerances during automated cycles.
The unit’s continuous stall torque is 0.33 Nm, which suits light moving loads that require fast acceleration without oversizing the drive amplifier. Rated speed reaches 10000 rpm, so small indexing axes can complete short strokes quickly while staying within the motor’s thermal limits. Electrical terminations exit on Side B and are pre-assembled to a connecting cable with a coupling unit, which helps simplify cabinet wiring and keeps cable strain away from the stator housing. Feedback is delivered by resolver feedback, a sensor type chosen for its shock tolerance and position feedback over one revolution. Standard housing style and balancing reduce vibration, and the motor uses size code 025 with length code A to keep the overall envelope short.
A centering diameter of 40 mm provides the pilot fit on mounting plates, while the blocking brake supplies 1.0 Nm of static holding torque to lock the shaft when power is removed. The motor is supplied with a plain shaft and a configuration with a shaft seal to help minimize lubricant migration from adjacent gear stages. The shaft end is standard and does not extend from the opposite face, allowing the rear of the motor to sit flush against fixtures. This layout supports compact mounting where rear clearance is limited.
