MDD071B-N-030-N2T-095PR2
Bosch Rexroth Indramat builds the MDD071B-N-030-N2T-095PR2 in its MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into rotary motion for positioning, conveying, and tooling axes in automated machinery. This arrangement suits packaging modules, transfer units, and machine-tool subaxes that need repeatable rotary motion in a compact installation. The frame size 071 and length code B provide moderate output in a compact envelope, while the blocking brake inside the housing helps keep the load in position when power is removed.
At standstill, the motor sustains 4.4 Nm of continuous torque, so the drive can hold or slowly index mechanical loads without overheating the stator. During motion, it reaches a nominal speed of 3000 rpm, which suits many general-purpose servo axes. Accurate mechanical alignment is aided by a 95 mm centering diameter that fits standardized mounting pilots. Power and feedback conductors exit to the operator's right, which helps when adjacent axes are installed close together. A sealed industrial connector carries the motor phases and protective earth, reducing wiring complexity compared with a terminal box.
For static holding, the internal brake supplies 6.5 Nm of torque, allowing vertical loads to remain fixed without external clamps. A shaft seal at the front bearing helps limit contamination ingress, and torque is transferred through a keyway shaft end that mates with keyed couplings or pulleys. Position data is returned through Digital servo feedback (DSF) from an integrated multiturn absolute encoder, so the drive can maintain closed-loop control and synchronize multiple axes without a separate reference run. Standard dynamic balancing and a rib-cooled housing support stable operation during routine industrial use.
