MDD071A-N-040-N2T-095GR2
Bosch Rexroth Indramat builds the MDD071A-N-040-N2T-095GR2, an AC servo motor in the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts electrical control signals into rotary motion for positioning and speed regulation in automated equipment. In a closed-loop axis system, it works with a matching controller to deliver controlled torque, stable speed, and accurate stopping behavior during repeated machine cycles. The unit uses a standard housing and standard rotor balancing, which supports installation in compact machine assemblies without added counterweights or special cooling hardware.
Its mechanical interface uses a 95 mm centering diameter that mates with pilot recesses on mounting plates. The motor supplies a continuous standstill torque of 2.2 Nm, giving reliable holding force while limiting thermal buildup at zero speed. Under load, it can reach a nominal speed of 4000 rpm, supporting rapid indexing cycles in compact automation equipment. Rotor position is monitored by an integrated multiturn absolute encoder, and feedback is transmitted through digital servo feedback (DSF) for closed-loop control across multiple revolutions. This feedback arrangement allows the drive to retain position information beyond a single turn, which helps on axes that move repeatedly through longer travel ranges. Size code 071 and length code A place the motor in a compact format suited to assemblies with limited installation space.
A blocking brake is factory installed, and it delivers 6.5 Nm of static torque to hold the axis during power loss. Power and feedback cabling exit on the right side through a connector, which can simplify routing along moving carriers and tight machine frames. An internal shaft seal helps reduce contaminant entry and protect the bearings, and the output journal uses a plain shaft with no side-B extension for direct coupling to gears or pulleys. This arrangement is well suited to compact pick-and-place heads, small gantries, and indexing tables that need repeatable motion and secure holding at standstill.
