Product Description:

Bosch Rexroth Indramat builds the MDD071B-N-040-N2M-095PB1, a synchronous servo unit in the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts command currents into rotational motion for coordinated machine axes in industrial automation. The model’s internal encoder supports closed-loop operation, and the integrated blocking brake maintains shaft position when power is removed, making the motor suitable for indexing tables, packaging stations, and other electronically controlled drives.

At standstill, the rotor produces a continuous torque of 4.4 Nm, allowing stable holding force without overheating during sustained dwell times. When the drive reaches its nominal speed of 4000 rpm, the torque-to-inertia ratio matches the dynamic requirements of pick-and-place or feed modules. A holding brake rated at 3.0 Nm links directly to the motor shaft so commanded stops are mechanically secured during power loss. Position data are returned through digital servo feedback from the integrated multiturn absolute encoder, allowing the controller to detect multiple revolutions and resume motion with full electrical commutation after downtime. The rotor and output shaft are balanced to the standard grade, limiting vibration that could shorten bearing life.

The motor has a centering diameter of 95 mm, which aligns the flange to the gearbox or machine plate. Power and feedback cables exit on Side B, and the round connector interface provides a compact connection point. The single-ended shaft is machined with a keyway, and a shaft seal prevents oil or coolant from entering the front bearing. Because the rear shaft end is omitted, installation depth stays compact for gantry axes. Size code 071 and motor length code B indicate the overall stack height in the MDD series, while the standard housing dissipates heat by natural convection.
