Product Description:

The MDD071B-N-040-N2T-095GB0 synchronous motor is produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. As a motor matched to digital drive controllers, it converts drive current into rotary motion for positioning and velocity control in automated machinery. The unit's B-length frame and size 071 housing place it in mid-range power classes commonly used on pick-and-place axes, packaging equipment, and light machine tool feeds. Its synchronous design supports accurate response to changing commands and steady operation during repeated indexing cycles. This layout suits compact machine axes that need precise motion without moving to a larger motor frame.

At standstill the motor can deliver 4.4 Nm of continuous torque, so thermal limits are not exceeded while the shaft resists load during static positioning. Under rated excitation it reaches a nominal speed of 4000 rpm, giving moderate peripheral velocity without overspeeding the rotor laminations. Accurate mechanical alignment is aided by a centering diameter of 95 mm, which fits common flange patterns used with this frame size. Power and feedback cables leave the housing on side B, allowing consistent routing where multiple axes are stacked. A single keyed connector on that face combines power and signal contacts and reduces the number of separate cable entry points at the motor housing.

Motion feedback is furnished by an integrated multiturn absolute encoder, permitting the drive to monitor position across multiple revolutions without homing. Within the drive loop, the encoder signals are transmitted as digital servo feedback (DSF), supporting high-resolution interpolation and automatic parameter detection. The mechanical output is provided by a plain shaft, so torque is transferred through friction couplings or compression hubs, and a fitted shaft seal limits lubricant escape and contaminant entry at the shaft exit. Standard dynamic balancing minimizes vibration, and the motor is supplied without a blocking brake for applications that use external holding mechanisms. Retained position data also supports restart behavior in systems that must preserve axis location between moves.
