Product Description:

The MDD090A-N-020-N2L-130PL1 is an AC synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it generates controlled torque and speed for positioning axes, pick-and-place modules, and other motion tasks in automated machinery. Its built-in feedback devices and mechanical interface allow the motor to connect directly to Rexroth drive modules, completing a closed-loop system that delivers incremental or continuous motion as required in industrial applications.

At standstill, the rotor can deliver 3.7 Nm of continuous torque, which is the steady holding capability without overheating. When the windings are energized for nominal mechanical output, the shaft turns at 2000 rpm, providing speed suitable for medium-duty positioning jobs. For emergency or power-off stopping, a blocking brake is fitted that clamps the shaft with 6.5 Nm of static torque. Installation is aided by a centering pilot of 130 mm in diameter, which seats the flange precisely on the machine frame. Position data are returned through digital servo feedback, so the drive can compensate for load variation and maintain the commanded trajectory.

The rotor and flange use standard balancing, so vibration remains low across the speed range. Power and encoder leads exit on the left side through a sealed connector, which suits cabinets that route cables along a single service channel. The standard housing encloses the stator, while a resilient shaft seal keeps lubricant inside and contaminants out. The single-ended keyway shaft couples to gearboxes or pulleys, and the design omits a side-B extension to simplify mounting. The motor uses size code 090 with length code A, and the left-side connection direction suits machines that integrate MDD motors with digital controllers.
