Product Description:

The MDD090B-N-040-N2L-130GA1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into rotary motion for positioning axes and regulated speed tasks in automated machinery. Integrated feedback support allows the connected servo amplifier to monitor rotor behavior continuously and correct deviations under changing load conditions. This makes it suitable for packaging, handling, and indexing equipment where repeatable acceleration and stable low-speed operation are required.

The motor reaches a nominal speed of 4000 rpm, allowing short cycle times when paired with suitable inverters. At standstill it provides 7.2 Nm of continuous torque, which supports stable holding force during controlled motion and dwell periods. A centering diameter of 130 mm helps align the motor accurately with flanges, gearboxes, or machine plates. Position data are returned through digital servo feedback (DSF), which supports closed-loop control of speed and position. The output uses a plain shaft, so torque is transferred through clamp-style or friction-based couplings rather than a keyed connection.

A blocking brake is integrated and provides 6.5 Nm of static torque to hold vertical or suspended axes when power is removed. Motor power and feedback conductors are routed through a connector on side A, which keeps the cable outlet on one end of the housing for straightforward routing. The enclosure uses a standard housing with no additional surface cooling features, so heat is dissipated through the motor body and surrounding air. The shaft end is standard without a side B extension, and a fitted seal helps limit the entry of contaminants while retaining internal lubrication. The rotor is factory balanced to a standard grade to help reduce vibration during operation. Housing dimensions correspond to size 090 and length code B, setting the motor's axial length for installation planning.
