Product Description:

The MDD090A-N-020-N2L-130GB2 is a synchronous AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified by the manufacturer as a motor for digital drive controllers, it converts commanded current into highly repeatable rotary motion so automated stations maintain positional accuracy. When coupled to a matching drive, the unit supplies closed-loop actuation for feed axes, pick-and-place arms, and auxiliary spindles across general-purpose manufacturing cells.

At rated conditions, the motor develops a continuous standstill torque of 3.7 Nm, giving machinery enough holding force without overheating when shafts are motionless. Its nominal operating speed reaches 2000 rpm, a value that sets the electrical frequency and gearing required for line throughput targets. An integrated blocking brake applies 11.0 Nm when power is removed, preventing load creep on vertical or indexing axes. Position data is returned through Digital servo feedback (DSF) so the drive can correct deviations every control cycle. All electrical terminations exit on side B, and a keyed circular connector simplifies cable connection. Standard dynamic balancing minimizes vibration, the housing follows the normal enclosure style, and the motor length code A designates the shortest 090 frame for compact panels.

The mechanical interface also follows standardized MDD geometry. A centering pilot of 130 mm aligns the flange precisely with mounting plates, while the output uses a plain shaft that mates with couplings or pulleys without keyways. The design retains internal lubrication by fitting a shaft seal, which helps protect the bearings from airborne coolant and dust. Size code 090 identifies the outer stator diameter used by compatible gearheads. The standard housing, the single plain shaft end, and the connector-based wiring support compact machine layouts.
