Product Description:

The MDD090C-N-020-N2M-110GA2 is a three-phase synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. When paired with digital drive controllers, this unit converts commanded current into precise rotational motion for positioning, conveying, and cyclic handling tasks in automated machinery. This arrangement allows closed-loop control of speed and position during repetitive machine cycles. It is suited to applications that require repeatable motion rather than simple constant-speed operation, and its mechanical outline fits modular production cells.

Its nominal shaft speed reaches 2000 rpm, indicating the upper continuous operating velocity that the drive can command without field weakening. At standstill, the motor can deliver 10.4 Nm of continuous torque, allowing static load support during dwell phases without overheating. An integrated blocking brake supplies a holding capacity of 11.0 Nm so vertical axes remain secured after power is removed. All power, brake, and encoder plugs are oriented on Side A, which helps keep cable routing orderly inside compact enclosures. A centering pilot of 110 mm helps maintain concentricity between the motor flange and the machine frame, while the multiturn absolute encoder and connector-based power interface are integrated into the standard housing with a shaft seal.

The frame designation 090 corresponds to the stator diameter, while length code C extends the active stack to raise torque density without changing mounting points. A plain shaft provides a simple coupling surface and supports backlash-free hub connections. Dynamic feedback is supplied through Digital servo feedback (DSF), allowing the controller to adjust phase current in real time for stable speed and position control. Standard balancing helps minimize residual vibration. The single-ended shaft arrangement avoids overhung loads on a second output side and suits medium-inertia gantry, press, and transfer axes.
