Product Description:

The MDD071A-N-040-N2T-095GB1 is an AC synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for pairing with digital drive controllers. It converts electrical power into precisely regulated rotary motion for positioning axes, gantries, and other automated assemblies where repeatable speed and torque control are required.

A centering pilot diameter of 95 mm aligns the motor housing to machine frames without extra shims, and all power and feedback plugs face Side B for consistent cable routing inside tight cabinets. The unit produces 2.2 Nm of continuous standstill torque, letting it hold moderate static loads while energized, and the integrated blocking brake supplies an additional 3.0 Nm when power is removed to secure vertical or suspended axes. During dynamic operation, a nominal mechanical speed of 4000 rpm supports fast cycle times in light-duty servo loops. Position data are captured by an integrated multi-turn absolute encoder, and its multi-turn counting removes the need for homing routines after each power-up. Electronic commutation data are returned through a shielded digital servo feedback (DSF) channel that minimizes signal latency between the motor and the controller.

The motor is built on the compact size 071 frame with an A length code to reduce overall depth in space-restricted machines. A factory-installed shaft seal blocks coolant splash and airborne oil from reaching the bearings, and the plain shaft mates directly with zero-backlash couplings. Standard balancing lowers residual vibration for smooth high-speed rotation, while a standard aluminum housing aids heat dissipation without external fins. The single molded connector supports secure cable connection and maintains IP-rated sealing integrity. Because the rear of the shaft is closed and no auxiliary output is provided, the motor’s plain front end remains the sole mechanical interface.
