Product Description:

The MDD071A-N-030-N2T-095GR2 is a synchronous motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current from an inverter into accurate rotary motion for industrial handling, tooling, and positioning tasks. This type of motor is commonly paired with a matched drive so speed and position can be regulated continuously during machine cycles. Standard dynamic balancing helps reduce residual vibration across the speed range, and a single circular connector carries both power and encoder lines to simplify cable routing at the machine.

The unit delivers a continuous standstill torque of 2.2 Nm, so the drive can hold static mechanical loads without stalling when the shaft is motionless. During motion, the rotor reaches a nominal speed of 3000 rpm, which supports direct coupling to gearheads or belt-driven mechanisms. A blocking brake inside the housing applies up to 6.5 Nm of holding torque, securing vertical or suspended axes during power loss. Position signals are returned through DSF digital servo feedback generated by an integrated multi-turn absolute encoder, enabling exact multi-revolution capture of shaft angle. Mechanical registration to adjacent frames is simplified by a centering diameter of 95 mm. The connection hardware is oriented to the right, so service cabling exits on that side of the motor.

The motor uses frame designation 071 and length code A, which indicate a compact housing size and lamination length for this model. A lubricated shaft seal blocks coolant or abrasive dust from the front bearing, and the plain shaft is supplied without keyways to suit clamp-style couplings. The shaft is present only on side A, while side B remains closed because the model is supplied without a secondary shaft end. A standard cast-aluminum housing protects the windings and maintains the intended thermal path for this frame.
