Product Description:

The MDD025A-N-100-N2G-040GA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts electrical commands into precise rotary motion for compact pick-and-place axes and light tooling spindles. The unit fits tight machine envelopes, and an integrated brake allows secure load holding when power is removed. Standard housing and balancing let the motor be mounted without extra vibration tuning, and its single shaft end streamlines coupling selection.

The servo’s continuous torque at standstill is 0.33 Nm, allowing it to hold lightweight loads without motion while drive current remains constant. During operation, the rotor can reach a nominal speed of 10000 rpm, enabling short cycle times in feeders and spindle duties. A centering diameter of 40 mm positions the stator concentrically against the mounting flange, keeping runout low. All power and feedback conductors exit on Side A, an arrangement that supports multi-axis panels. The built-in resolver feedback provides rotor angle information over the full speed range, supporting rapid commutation and torque linearity. Standard balancing limits residual vibration, and the compact length designated by code A helps the motor fit close to guide rails.

Process reliability is enhanced by a blocking brake rated at 1.0 Nm; it immobilizes the rotor when the control system removes power. The pluggable connector interface allows quick connection and seals against dust through an O-ring. A plain shaft with a factory-installed shaft seal helps prevent lubricant egress and protects internal bearings from coolant splash. The motor size code 025 identifies a compact frame that accommodates the standard housing contour and cooling path.
