Product Description:

The MDD071B-N-040-N2S-095PA0 synchronous motor is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies closed-loop rotational power for precise positioning, indexing, and speed control on automated production equipment. The unit couples electrically to the drive inverter and mechanically to the load, converting regulated DC bus energy into repeatable motion for packaging, material handling, and printing machines. This operating principle allows the motor to respond quickly to command changes while maintaining stable rotation through varying process demands.

At stall, the rotor delivers a continuous torque of 4.4 Nm, so the drive can hold moderate loads without overheating when motion is paused. During dynamic operation, it reaches a nominal speed of 4000 rpm, which suits medium-speed tools and conveyors. A centering diameter of 95 mm provides the locating fit on machine frames and helps maintain concentric alignment between the motor and gearbox. Position data is returned through digital servo feedback, allowing the controller to regulate current in real time and correct motion deviations as load conditions change. Power and feedback plugs are oriented on side A, which helps simplify cable routing when the flange faces the work zone. The keyed shaft end transfers torque to the driven mechanism without slip during normal operation.

A shaft seal blocks grease and dust at the output journal, and the rotor is balanced to a standard grade to reduce vibration during continuous duty. The housing is made of standard cast aluminum, and the frame follows size code 071 with length code B to fit compact machine spaces. Mechanical locking must be provided externally because the motor is supplied without a blocking brake. Electrical connection uses a keyed connector instead of a terminal box, and the shaft has a standard keyway with no side B extension. This arrangement keeps the cable interface near the connection side and leaves the opposite end clear for direct coupling to the driven load.
