Product Description:

The MDD071B-N-030-N2S-095GA1 is a synchronous servo unit manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It interfaces with digital drive controllers to deliver commanded torque and speed for positioning axes in industrial automation. The motor ships with a blocking brake for static load holding, and its standard housing and rotor balancing allow direct installation without additional vibration control measures. This arrangement supports accurate starts, stops, and repeatable motion in packaging, handling, and general machine tool axes.

A centering diameter of 95 mm aligns the front flange precisely on mounting plates, while the stator can deliver 4.4 Nm of continuous standstill torque so actuators can remain energized at low speed without thermal overload. The rotor can reach a nominal speed of 3000 rpm, matching common operating ranges used in packaging and handling machinery. Position data is returned through digital servo feedback, giving the controller high-resolution information for closed-loop regulation and stable low-speed response. Power and feedback leads exit toward Side A, simplifying cable runs when the motor sits at the end of a linear slide. The standard single-ended shaft and class-B overall length help the motor fit machine layouts with limited installation depth.

The integrated brake supplies 3.0 Nm of holding torque to lock the rotor during power-off conditions or emergency stops. Mechanical power is transmitted through a plain shaft, which suits clamping-style couplings and avoids the stress concentration associated with a keyed connection. Electrical terminations are made through a sealed connector, which allows a secure connection and helps protect the connection area when locked. The motor belongs to frame size 071, and it includes a shaft seal that helps limit lubricant migration into the motor interior.
