Product Description:

The MDD093A-N-020-N2M-130PR0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts commanded current into controlled rotary motion for positioning and velocity tasks in packaging lines, gantry axes, and material-handling stations. This arrangement supports closed-loop axis control in automated machinery that requires repeatable motion. The unit’s mechanical envelope and electrical interface match the common mounting grid of the series, so it fits typical multi-axis automation platforms without requiring a custom motor layout.

Accurate mechanical referencing is provided by a centering flange of 130 mm, which locates the stator housing concentrically to the machine plate while the rotor is balanced to a standard grade. At standstill, the motor can sustain 9.2 Nm of continuous torque, allowing it to support static loads without overheating while the drive remains energized. A nominal operating speed of 2000 rpm sets the baseline speed for the connected drive and the coupled mechanism. Position and velocity information are returned through Digital servo feedback (DSF) from the integrated multi-turn absolute encoder, giving the controller absolute shaft position after power-up and eliminating the need for a reference run after every restart. Because the design is supplied without a blocking brake, applications that need power-off holding must use an external brake or maintain motor excitation during standby.

Power and feedback conductors exit through a connector on the right side, which can simplify cable routing where adjacent axes share trunking. Output torque is transmitted by a shaft machined with a keyway, so couplings or pulleys can be secured without relying only on friction. A factory-installed shaft seal helps minimize lubricant migration and particulate ingress at the bearing seat. The frame code 093 indicates the motor size, while length code A keeps the overall mass and axial dimension low for compact machine spaces.
