Product Description:

The MDD090B-N-040-N2L-110GA1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. This model is intended to pair with digital drive controllers in automated machinery where compact rotary motion and closed-loop regulation are required. Within such systems, the motor converts electrical power into precisely controlled mechanical rotation, allowing axes to accelerate, position, and hold loads under software control. Its operating profile suits machinery that needs repeatable motion, steady servo response, and consistent feedback during changing load conditions.

At the rotor's stalling point, the motor can deliver a continuous torque of 7.2 Nm, allowing steady force without overheating during static clamping or slow indexing moves. When commanded to run, its rated mechanical speed reaches 4000 rpm, supporting fast duty cycles common in packaging and handling lines. Mounting accuracy is aided by a centering shoulder diameter of 110 mm, which helps align the flange with associated gearboxes or machine frames. All power and feedback leads exit on side A, which can simplify cable routing where one preferred connection direction is needed. The electrical interface uses a keyed connector, so the cable set attaches directly to the housing without requiring an open terminal area.

Operational stability is increased by an integrated blocking brake that produces 6.5 Nm of holding torque to secure vertical or high-inertia loads when power is removed. Position feedback is supplied through digital servo feedback (DSF), allowing the drive to monitor rotor movement and maintain synchronized control loops during motion. The motor frame corresponds to size code 090, giving a compact housing suited for moderate power applications. A plain shaft with a shaft seal supports direct coupling through clamp or press-fit hubs while helping limit lubricant migration and contaminant entry. The feedback and brake combination lets the motor remain under control during normal motion and hold position when the axis is stopped.
