Product Description:

The MDD090A-N-020-N2M-130GA0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Intended for pairing with digital drive controllers, it converts electrical power into controlled rotary motion for positioning and velocity functions in automated lines, pick-and-place gantries, and light machining centers. A standard housing, standard rotor balancing, and a plain shaft without a side B extension allow quick mechanical integration while keeping vibration and space requirements low. It is intended for digital drive controllers, so control loops are handled by the companion inverter.

The motor delivers a continuous standstill torque of 3.7 Nm, enabling it to support static loads without thermal overload when held for extended periods. Under dynamic operation it reaches a nominal speed of 2000 rpm, matching drive frequencies typical of mid-range industrial axes. Accurate flange seating is provided by a centering diameter of 130 mm, which aligns the stator concentrically with adjoining machinery. All power and feedback conductors exit on the A-side because the connection hardware uses a connector oriented toward side A, which simplifies internal cabinet routing. To protect the bearings from dust and coolant, the output shaft is equipped with a shaft seal.

Position data is supplied by the integrated multiturn absolute encoder, allowing the axis to recover coordinates immediately after power is restored. Feedback signals are transmitted through digital servo feedback (DSF), which reduces analog drift and provides high-resolution commutation. As the unit is delivered without a blocking brake, external clamps or sustained drive torque must be used to hold vertical loads when de-energized. The frame belongs to size 090 and is paired with the compact length code A, making the motor suited to installations where depth is limited yet precise synchronous performance remains essential.
