Product Description:

The MDD093B-N-020-N2M-110GL1 is a synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current from an Indramat drive into precise rotary motion for positioning and speed-controlled tasks in automated machinery. The integrated multiturn absolute encoder supplies closed-loop position data during operation, and the blocking brake holds the axis when power is removed. Because feedback is built into the motor, the drive can monitor shaft position continuously and maintain accurate response during acceleration, deceleration, and holding.

At standstill, the motor can deliver a continuous torque of 14.5 Nm, allowing it to hold or slowly move mechanical loads without additional cooling. Under rated electrical frequency, it reaches a nominal speed of 2000 rpm, so gear ratios can be selected around a predictable base velocity. The blocking brake provides 11 Nm of static holding torque to keep the shaft fixed during downtime. A centering diameter of 110 mm aligns the motor with machine frames for accurate coaxial mounting. The frame size 093 places the unit in a medium motor class suited to compact servo axes.

Electrical and feedback terminations are routed on the left side of the housing through a keyed connector, which helps when adjacent drives and cables are placed close together. Commutation data returns to the drive through DSF, so high-resolution feedback is transferred digitally instead of through analog sinusoidal channels. The steel shaft is machined as a plain shaft, and a factory-installed shaft seal helps prevent lubricant migration across the front bearing during repeated motion. Motor length code B, a single shaft end, and a standard molded housing keep the layout straightforward for enclosed machine installations.
