Product Description:
The MDD090A-N-020-N2M-130GL1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts commanded current into controlled rotary motion for positioning axes and feed applications in automated machinery. The motor uses size 090 with the compact A length, which helps it fit installations where mounting space is limited without moving to a larger frame. Its housing supports direct flange mounting, and the shaft seal helps protect internal parts from splashed coolant and dust during routine machine operation. This type of motor is commonly used on indexing, transfer, and positioning axes.
The motor has a centering shoulder of 130 mm, which helps align the flange with a gearbox or bell housing during installation. The power and feedback interface is located on the left side and uses a keyed circular connector, making cable routing easier when space is restricted around the machine frame. Under continuous stall conditions, the motor delivers 3.7 Nm of torque, while the winding supports a nominal speed of 2000 rpm for moderate-inertia loads that need stable acceleration and repeatable speed control. An integrated blocking brake provides 6.5 Nm of holding torque so an axis can remain stationary when power is removed or a safety circuit is active.
Position data is supplied by an integrated multi-turn absolute encoder, which allows the control system to know rotor position immediately after power-up instead of requiring a separate homing movement. The feedback signal is transmitted through digital servo feedback (DSF), providing the closed-loop data needed for speed and position control through the matched drive. The rotor uses standard balancing to help keep vibration low across the operating range and reduce disturbance at the coupling. The output end is a plain shaft, and there is no second shaft extension on side B. This shaft style is typically matched with clamping hubs or similar couplings.
