Product Description:

The MDD025B-N-100-N2K-040PC1 is a compact servo unit from Bosch Rexroth Indramat in the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts regulated drive current into precise rotary motion for light-duty positioning, indexing, and spindle functions inside automated machinery. Its compact form suits installations where limited space and quick response are both important.

This model reaches a nominal speed of 10000 min⁻¹, allowing high cycle counts when paired with appropriately rated drives. Its continuous torque at standstill is 0.60 Nm, so the axis can hold small loads without movement during dwell periods. A blocking brake is integrated, and its braking torque is 1.0 Nm, supplying mechanical restraint when power is removed. The centering pilot on the flange measures 40 mm in diameter, giving a repeatable reference for concentric mounting. All power and feedback conductors exit on Side A, which simplifies cable routing where motors are mounted in tight rows. An integrated absolute encoder delivers position data at power-up, and the 025 frame size keeps overall mass low for dynamic acceleration.

Standard dynamic balancing reduces vibration, and the housing uses the standard MDD form used with common accessories. Electrical terminations are made through a Connecting cable with coupling unit, so the motor can be disconnected without removing the housing from the machine. Resolver electronics furnish Resolver feedback for robust speed control in electrically noisy environments. The stator uses Motor Length Code B, which indicates the active stack depth for this 025 frame. A hardened shaft with a keyway transmits torque into couplings, and a shaft seal limits lubricant migration along the journal.
