MDD065A-N-040-N2M-095PL0
Bosch Rexroth Indramat manufactures the MDD065A-N-040-N2M-095PL0 as part of its MDD Synchronous Motors series. This unit is a compact motor designed for digital drive controllers where precise velocity and torque commands are required. A standard housing and standard rotor balancing minimize vibration when the axis accelerates. Because the model is supplied without a blocking brake, holding force must be achieved through the drive itself or external mechanics. Within automated assembly lines, pick-and-place modules, or indexing tables, the motor converts electrical drive signals into rotational motion that can be tightly coordinated with other axes, supporting high cycle rates and repeatable positioning.
The mechanical interface uses a 95 mm centering diameter, allowing the housing to seat accurately against mounting surfaces. At standstill, the motor delivers 0.8 Nm of continuous torque, supplying holding force without thermal overload. During motion, it reaches a nominal speed of 4000 rpm that suits high-cycle positioning tasks. Power and feedback conductors exit on the left side, simplifying cable routing when the drive is mounted to the right of the axis. A removable connector couples the unit to system wiring. The frame follows motor size 065 with the shortest A length code, so the body remains narrow and easy to fit inside compact machine columns. The output is provided only on side A; there is no shaft on side B, which simplifies guarding at the rear of the servo package.
Closed-loop accuracy comes from an integrated multi-turn absolute encoder that retains position over power cycles. Its signal travels through digital servo feedback (DSF), ensuring synchronous communication with compatible Rexroth drive amplifiers. A shaft seal blocks dust and coolant at the output flange to protect the bearing arrangement. The output shaft uses a keyway profile, allowing positive-drive couplings that prevent slip at the available torque and speed.
