MDD071B-N-060-N2T-095PA1
The MDD071B-N-060-N2T-095PA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for use with digital drive controllers in automated production lines. It occupies the 071 frame class with motor length code B, giving the unit a compact form that suits space-limited axis assemblies. A standard housing encloses the windings, and the rotor is balanced to a standard grade to reduce vibration transfer into the machine structure during repeated motion. Power and feedback wiring attach through a sealed connector, while the shaft is present only on the drive side so the rear remains closed to other mechanical couplings. This layout supports use in positioning axes where stable alignment, protected connections, and predictable dynamic behavior are required throughout normal production duty.
Mechanical location is aided by a 95 mm centering diameter that aligns the stator face with gearboxes or flange adapters. The motor can hold loads continuously at 4.4 Nm without exceeding its thermal limits, and it reaches a nominal operating speed of 6000 rpm when paired with a matched inverter. Cables exit on Side A, which helps keep conductors away from moving machine elements when the motor is mounted nose-down. An integrated multiturn absolute encoder stores position across power cycles, letting the controller recover axis coordinates after a shutdown without requiring a homing routine. This arrangement supports quick return to controlled motion when the system is restarted and helps maintain accurate position tracking over repeated operating cycles.
When the drive is disabled, a blocking brake supplies 3.0 Nm of static torque to prevent back-driving on vertical axes. Closed-loop control is supported by the motor’s digital servo feedback (DSF) channel, which transmits high-resolution position data without the analog drift associated with older feedback methods. A shaft seal helps block lubricant migration into the stator cavity, and torque is delivered through a keyway shaft for positive mechanical coupling to the driven load. These features support stable motion control in applications that require accurate stopping, secure load holding, and reliable feedback during frequent starts, stops, and speed changes.
