Product Description:

The MDD025C-N-100-N2K-040PD1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied in the MDD Synchronous Motors series. It is intended for digital drive controllers and converts drive current into rotary motion for light-duty positioning axes, indexing tables, and compact pick-and-place modules in automated machinery. The design suits compact motion systems that need quick response and repeatable positioning in a small installation space. In transfer and indexing applications, that layout helps the axis start and stop cleanly during short, repetitive moves.

During continuous stall conditions, the rotor can deliver 0.90 Nm of torque, which is the maximum load the motor can hold without overheating when locked in position. The motor reaches a nominal speed of 10,000 rpm, enabling high cycle rates in small-format actuators. A blocking brake integrated on the non-drive end supplies 1.0 Nm of static holding torque, preventing drift when power is removed. Mechanical alignment is supported by a centering diameter of 40 mm, while all power and feedback terminations leave the housing on side B, keeping cable bends consistent in multi-axis assemblies. The motor uses standard dynamic balancing and a standard enclosure. The 025 frame with length code C gives the motor its stack height and thermal mass.

An integrated absolute encoder provides single-turn position data, and a secondary resolver feedback channel supplies analog rotor information for drives that use transformer-based sensing. Connection to the drive is handled through a connecting cable with a coupling unit, which eliminates separate junction boxes and shortens installation time. The shaft uses a keyway profile so torque is transmitted without slip, and a shaft seal is present to limit lubricant escape into the surrounding cabinet. This shaft arrangement supports direct coupling to driven elements that need secure torque transfer and a sealed shaft passage. The shaft end is supplied only on the drive side, reducing inertia on the auxiliary face and matching applications that do not require a through-shaft configuration.
