Product Description:

The MDD090C-N-020-N2M-130GL2 is a servo motor manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Intended for coupling with digital drive controllers, the motor delivers commanded torque and speed to rotary axes in machine tools, packaging lines, or handling systems where closed-loop motion is required. Its synchronous design supports accurate response to changing command values during positioning and speed-control tasks. This allows the connected drive to maintain stable motion during repeated starts, stops, and direction changes.

The mechanical interface uses a centering diameter of 130 mm, which ensures concentric alignment with mounting flanges. During continuous stall operation, the motor can produce 10.4 Nm of torque, allowing it to hold or slowly move loads without overheating. Rated operation is reached at 2000 rpm, a speed that balances dynamic response with bearing life. Power and feedback conductors exit on the left side through a sealed connector, streamlining cable routing in cabinets where right-side clearance is limited. Position data are generated by an integrated multiturn absolute encoder, giving the drive immediate angle information after power-up. For vertical or suspended loads, the fitted blocking brake supplies 11.0 Nm of holding torque so motion is restrained when the drive is disabled.

The motor frame uses size code 090 and length code C, a combination that sets the active magnetic length and overall weight for medium-power applications. A plain shaft is provided to couple with clamping hubs or shrink disks, while a shaft seal helps prevent lubricant migration into the stator chamber. Standard balancing limits vibration and helps protect precision gearboxes, and the housing uses the series' standard cooling surface geometry. Connection is made with a circular connector, and digital servo feedback supports high-resolution commutation. The shaft end is supplied only on side A, reducing mass on the non-drive side and simplifying integration with digital drive controllers.
