MDD071A-N-040-N2S-095PA2
Bosch Rexroth Indramat builds the MDD071A-N-040-N2S-095PA2 for inclusion in the MDD Synchronous Motors series. This brushless AC motor is supplied for use with digital drive controllers, where it converts electrical energy into tightly controlled shaft rotation for conveyors, pick-and-place axes, and other automation platforms. By combining permanent magnets with electronic commutation, the unit delivers fast torque response and accurate speed control in applications where cycle times are short and positioning tolerances are narrow.
The mechanical interface includes a centering diameter of 95 mm, allowing a close fit to standard mounting flanges and supporting coaxial alignment between the motor and the load. A nominal speed limit of 4000 rpm is the highest continuous shaft speed that can be reached under rated voltage without exceeding thermal limits. Continuous output at standstill is 2.2 Nm, so the motor can hold moderate static loads when locked by the control system. Power and feedback conductors exit on side A through a sealed connector, which helps simplify cabinet layout and reduce cable strain. The output shaft uses a keyway for positive torque transmission to pulleys or couplings while helping resist slip under peak torsion.
Inside frame class 071 and length code A, the rotor is balanced to the standard grade, which helps limit vibration transfer to precision fixtures during dynamic operation. An integrated holding brake rated at 6.5 Nm engages when the drive is disabled because the motor is supplied with a blocking brake, helping prevent vertical loads from drifting. Position data is returned through digital servo feedback, which sends rotor information to the controller for high-resolution commutation and stable motion control. A shaft seal protects the internal bearings, and the standard housing helps resist airborne coolant mist and dust in typical enclosure environments.
