Product Description:

The MDD090B-N-040-N2L-130GR2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for digital drive controllers, it converts regulated electrical power into rotary motion for automated handling, packaging, and processing equipment. Integrated position feedback lets the controller adjust torque and speed in real time, which supports accurate starts, stops, and speed changes during cyclic machine operation. This arrangement suits machine axes that need repeatable motion without adding separate external feedback hardware.

The motor has a nominal speed of 4000 rpm, which gives the shaft a high continuous operating speed for dynamic machine cycles. At standstill it can sustain 7.2 Nm of torque, so the axis can maintain position or move slowly under load without excessive heating. An internal blocking brake applies 11.0 Nm when supply power is removed, which helps secure vertical or safety-related axes during stopping. Position data reaches the controller through digital servo feedback (DSF), allowing the drive to monitor rotor position for closed-loop control. All power and feedback leads exit on the right side, and the 130 mm centering diameter helps align the motor accurately on the mounting flange.

The output uses a plain shaft for direct connection to couplings or pulleys, and it includes a shaft seal to help limit contaminant entry and lubricant migration. The motor uses size 090, which places it in a common frame class for this product line and supports installation where that mounting envelope is required. Standard dynamic balancing helps reduce vibration during rotation, while the standard uncooled housing suits enclosure-mounted systems that rely on the surrounding machine layout for heat removal. Electrical connection is made through a single circular connector, and the shaft is present only on the drive side because there is no second shaft extension on side B.
