Product Description:

The MDD025B-N-100-N2G-040MC0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts drive current into precise mechanical rotation for positioning and velocity loops in automated machinery. The unit belongs to a compact frame class and uses a standard housing, allowing it to fit tight multi-axis assemblies where high spindle speeds are required. In high-speed assembly stations, the motor can couple directly to gearheads or load shafts without intermediate belts, allowing direct servo control.

The motor has a continuous standstill torque of 0.60 Nm, which means the rotor can deliver this torque indefinitely while locked without exceeding thermal limits. During motion, the motor reaches a nominal speed of 10000 rpm, which suits light-inertia tools that require short cycle times. A centering diameter of 40 mm helps align the flange with mating fixtures and reduces radial runout. The shaft has a keyway so pulleys or couplings can be mounted without slip. Its 025 size code and B length keep the motor compact while providing enough stack height to maintain magnetic flux. Standard balancing also limits residual vibration and helps protect adjacent bearings.

Electrical and mounting interfaces are arranged on Side A, and the power group uses a connecting cable with coupling unit that simplifies installation by eliminating field-fabricated plugs. Resolver feedback provides rotor position data for closed-loop commutation. The motor is supplied without a blocking brake, so an external holding device is required when the load must remain fixed at standstill. For clean installations, the front end is built without a shaft seal, and the standard shaft end does not include a secondary output on side B.
