Product Description:

The MDD025C-N-100-N2K-040FC0 is a compact synchronous servo motor from Bosch Rexroth Indramat’s MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it provides controlled torque and speed for tightly regulated positioning in automated assembly cells, small pick-and-place stages, and packaging stations. The unit uses the standard housing style for this motor family and fits applications that need compact motor dimensions without external cooling hardware. Its compact format also suits axes where limited installation space and accurate speed response are important.

This motor has a centering diameter of 40 mm, which helps align the flange accurately on gearboxes or mounting plates. Power and feedback leads exit on side A, so clearance is required on that face during installation. The electrical connection uses a connecting cable with a coupling unit, which allows the motor to be connected without a fixed terminal box. At standstill, it can deliver 0.90 Nm of continuous torque, which is the thermal limit for stationary operation. Position data are provided by an integrated absolute encoder, and this arrangement lets the drive retain position information after power cycling. The motor also has standard dynamic balancing, frame size 025, and motor length code C.

The motor is supplied without a blocking brake, so any static load must be held by the drive or by external clamping hardware. Rotor angle references are also available through resolver feedback, supporting drive systems that use analog position signals. During motion, the motor can run up to 10000 rpm, which supports high-speed indexing on small axes and miniature gear stages. The output uses a plain shaft and has no shaft extension on side B. It is delivered without a shaft seal, so the front bearing should be protected from fluid ingress in washdown areas. The standard housing does not require separate cooling accessories, which helps keep the motor package compact.
