Product Description:

The MDD090A-N-020-N2M-110PL1 servo motor is manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is a compact rotary actuator intended for use with digital drive controllers in automated equipment. By providing closed-loop torque and position control, it helps machinery execute repeatable cycles, align tooling, and follow programmed motion profiles without backlash from intermediate transmission elements. This operating style suits indexing tables, feed axes, and other factory applications that rely on direct and predictable servo response.

At a nominal speed of 2000 rpm, the rotor supports medium-duty positioning cycles while remaining synchronized with the commanded drive frequency. The continuous torque available at standstill is 3.7 Nm, which allows the shaft to hold static loads without overheating during normal duty. Mounting alignment is aided by a centering diameter of 110 mm, and the assembly uses a standard balancing grade to reduce residual vibration. Power and feedback conductors exit on the left side through a sealed connector, which can simplify cable routing in multi-axis machine layouts. The motor uses size code 090 and length code A, and the standard housing provides mechanical protection without external cooling hardware.

The mechanical interface uses a keyway shaft with an integrated shaft seal and a standard single-ended configuration, so there is no side-B shaft extension. Position data comes from an integrated multi-turn absolute encoder and is transmitted as digital servo feedback (DSF) to the drive, which allows position retention through multiple revolutions and supports homing-free startup. For stopping security during power loss or emergency conditions, a blocking brake supplies 6.5 Nm of holding torque. This arrangement helps the motor remain secure at standstill on axes where gravity or external force could otherwise move the load.
