Product Description:

The MDD071A-N-030-N2T-095GB0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts electrical energy into controlled rotary motion for tasks such as positioning axes, indexing tables, or light-duty pick-and-place units. The model integrates its feedback devices and power terminations into a compact frame, allowing it to pair with Rexroth or third-party servo amplifiers used across general automation cells.

The centering pilot on the flange is 95 mm, providing an accurate reference surface so the stator can be aligned coaxially with a gearbox or machine frame. Power and signal conductors exit on Side B through a sealed connector. At standstill, the electromagnetic package delivers 2.2 Nm of continuous torque, allowing the motor to hold loads without overheating while the drive maintains zero speed. A rated speed of 3000 rpm supports rapid cycle times in medium-inertia applications. Position data is furnished by an integrated multi-turn absolute encoder, so the controller always knows rotor location after power loss and does not require a homing move before operation resumes.

Feedback signals are transmitted as digital servo feedback (DSF), permitting high-resolution phase angle information to reach the drive for tight current control loops. A resilient shaft seal blocks coolant splash and fine particulate from entering the bearing cavity, which helps protect the bearings in passively ventilated enclosures. The frame corresponds to size 071, and the motor uses a standard balancing grade, a plain output shaft, and a housing style suited to direct coupling with lightweight loads. It also has frame length A and no blocking brake, so holding must be provided by an external mechanism when the axis is stopped.
