Product Description:

The MDD071B-N-060-N2T-095PB2 is a synchronous AC motor produced by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical power from servo inverters into mechanical rotation for precise positioning and speed control in automated machinery. It is intended to drive mid-range axes on packaging machines, material-handling gantries, and other installations where high speed combined with moderate torque is required. It is commonly used in closed-loop motion systems that need repeatable response during frequent starts, stops, and direction changes.

The rotor assembly is balanced to the standard grade so vibration remains within DIN limits at peak shaft velocity. When installed, the stator seats against a centering pilot of 95 mm, enabling precise concentric alignment to attached gearboxes or frames. Power and feedback leads exit from side B of the housing, simplifying cable routing inside compact cabinets. At standstill, the motor can deliver a continuous torque of 4.4 Nm, and under rated excitation it reaches a synchronous speed of 6000 rpm. Position and velocity data are returned to the drive using digital servo feedback (DSF), allowing tight current control across the full speed range.

In operation, the built-in blocking brake supplies a holding torque of 6.5 Nm, allowing suspended or vertical loads to remain fixed after power is removed. Position transducers are embedded within an integrated multiturn absolute encoder, so the axis can recover its exact orientation without homing after each restart. Electrical and feedback terminations are realized through a single industrial connector, which reduces the number of separate connection points. Drive power is transferred through a keyed shaft; the keyway supports positive mechanical locking with couplings, while a factory-installed shaft seal helps protect the bearing set from coolant spray. The motor is built in size 071 with length code B, uses a standard aluminum housing for convection cooling, and has a single shaft end on the drive side to keep the overall length compact.
