Product Description:

The MDD093B-N-020-N2M-110GB1 synchronous motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended for digital drive controllers and converts command signals from a servo amplifier into precise rotational motion that can be synchronized with other axes in automated machinery. Its design supports applications that require moderate speed, repeatable positioning, and a built-in holding option on packaging lines, material-handling gantries, or process equipment. In these roles, the motor supports closed-loop control through its onboard feedback devices and fits the dimensional envelope common to other members of the series.

The continuous torque available while the rotor is locked is 14.5 Nm, enabling the axis to resist load forces without external gearing during dwell periods. Under rated excitation, the motor reaches a nominal speed of 2000 rpm, which pairs well with low-speed screw drives and belt transmissions used in general automation. Position retention during power-off is provided by an internal blocking brake that supplies 11 Nm of static torque. A centering diameter of 110 mm aligns the housing against mounting flanges, while power and feedback conductors exit on side B so cable routing can remain consistent with legacy wiring paths.

The motor uses digital servo feedback (DSF) together with an integrated multi-turn absolute encoder to report shaft position over the full mechanical revolution range, eliminating the need for homing cycles. Electrical connection is made through a keyed connector, and the output shaft is a plain shaft with a shaft seal to help prevent lubricant migration into the stator cavity. Standard balancing limits vibration, and the motor has frame length B with a 093 frame size for compatibility with earlier drives. The motor also has a standard housing and a shaft end only on the drive side, and the internal brake keeps the package compact for vertically oriented loads.
