Product Description:

The MDD090B-N-040-N2M-130GL0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded current into rotary motion for indexing tables, pick-and-place gantries, and other automation axes. In these applications, the unit couples directly to machinery through its output shaft while internal feedback closes the loop to the drive. That arrangement supports repeatable positioning and stable speed regulation during frequent starts, stops, and direction changes in industrial equipment.

The nominal speed is 4000 rpm, which is the maximum synchronous velocity the rotor can track under rated voltage. At standstill, the motor sustains 7.2 Nm of continuous torque, so low-speed holding and inching sequences do not cause thermal overload. A centering diameter of 130 mm aligns the frame to mounting flanges and helps maintain coaxial accuracy during installation. Position data comes from an integrated multi-turn absolute encoder, and that information is transferred to the controller through digital servo feedback (DSF). This feedback arrangement supports precise position monitoring across multiple revolutions and helps the drive maintain accurate closed-loop motion.

Electrical power and feedback exit on the left side through a keyed connector, which can simplify cable routing inside compact cabinets or along crowded machine frames. The mechanical envelope follows size code 090 and motor length code B, giving the unit a form factor suited to mid-range servo axes where space and response both matter. The output member is a plain shaft without a side B extension, making it compatible with compression couplings or belt pulleys. A shaft seal protects the bearing region, and because the motor is supplied without a blocking brake, vertical loads must be secured by external holding devices when power is removed.
