Product Description:

The MDD071C-N-060-N2S-095PB1 is a synchronous servo motor produced by Bosch Rexroth Indramat for use with digital drive controllers in the MDD Synchronous Motors series. It supplies closed-loop rotary motion to automated axes where repeatable speed and torque are required, such as indexing tables, pick-and-place heads, and packaging spindles. Its integrated blocking brake keeps loads in position when power is off, while the shaft configuration follows IEC dimensions for straightforward coupling to gearboxes or pulleys. This arrangement supports accurate motion control in machines that need stable response during repeated starts, stops, and holding cycles.

The motor develops a continuous standstill torque of 6.6 Nm and reaches a rated speed of 6000 rpm, allowing high-cycle operation on compact mechanical stages. For short intervals, the blocking brake can hold up to 3.0 Nm, helping prevent back-driving during power loss or emergency stops. Frame identification follows size code 071 with length variant C, giving an active stack suited to medium-inertia loads. A centering diameter of 95 mm aligns the flange precisely to machine frames, and the rotor is ground to a standard balancing grade so additional counterweights are not necessary. The housing uses a standard design, so no external cooling channels are machined into the stator body.

Cabling exits on Side B through a sealed circular connector that carries power, brake, and feedback signals from a drive-mounted cable set. Position data is generated by digital servo feedback, enabling fine velocity loops without separate encoders. A fitted shaft seal helps block lubricants and dust from entering the bearing set, and the single-ended shaft uses a keyway to transmit torque through keyed hubs. The absence of an opposite-side shaft end simplifies mounting in tight spaces, and the integral connector shortens installation time compared with a hardwired terminal chamber.
