Product Description:

The MDD065A-N-040-N2M-095GR0 is a synchronous servo unit produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is installed in automation cells to deliver regulated rotary motion under closed-loop control. By pairing with dedicated inverters, the motor provides repeatable positioning for tasks such as lightweight pick-and-place axes or small indexing tables while its standard housing allows integration inside protected machine enclosures.

The motor develops a continuous standstill torque of 0.8 Nm, giving a fixed value for holding or low-speed feed duties without excess heating. Under rated electrical frequency, it can run at a nominal speed of 4000 min⁻¹, supporting rapid cycle moves on short-stroke mechanisms. Accurate mechanical alignment is helped by the 95 mm centering diameter, which mates with flange bores to keep runout low. Position is reported by an integrated multi-turn absolute encoder; because the encoder counts revolutions internally, the axis retains its position through power cycles without homing. Feedback signals are passed through Digital servo feedback (DSF), supplying the drive with real-time rotor angle data for tight velocity and torque loops. Standard balancing limits residual vibration at high speed, and the power and feedback connectors are oriented to the right side of the stator to suit cabinet layouts.

Mechanically, a plain shaft interfaces with couplings or pulleys, and a shaft seal is fitted to restrict coolant or dust ingress along the journal. The unit is supplied without a blocking brake, so external holding devices or motor torque must secure vertical loads when power is removed. Frame size 065 combined with length code A yields a compact package that is only 184 mm long, and the single-ended shaft arrangement without a side B extension simplifies mounting. A molded circular connector carries both phase power and encoder leads, and the standard housing finish matches other MDD motors for uniform cabinet assembly.
