Product Description:

Bosch Rexroth Indramat produces the MDD090C-N-020-N2M-110GL2 as part of the MDD Synchronous Motors series. This motor is intended for digital drive controllers where precise torque and position control are required in automated assembly lines, packaging stations, and similar tasks. By supplying regulated rotary motion under closed-loop feedback, the unit acts as the electromechanical interface between the drive electronics and the mechanical load. Its compact housing and integrated feedback hardware allow installation in multi-axis systems without an external encoder. The motor uses a standard housing and rotor balancing to support smooth operation across a wide speed range.

The motor delivers a continuous torque of 10.4 Nm at standstill, so the shaft can hold or slowly index loads without exceeding thermal limits. During motion, it reaches a nominal speed of 2000 rpm, which suits gantry axes that favor moderate speed over high acceleration. A blocking brake rated for 11.0 Nm is integrated to secure vertical loads whenever power is removed. Electrical and feedback conductors exit on the left side through a keyed connector, which simplifies routing and helps prevent polarity errors. Standard dynamic balancing helps reduce vibration when the rotor runs near rated speed. The C length code places the motor in the mid-range body size within the 090 frame group.

The centering pilot has a diameter of 110 mm, helping the motor seat accurately on the machine face. Position information comes from an integrated multi-turn absolute encoder that works with digital servo feedback to give the drive high-resolution data over the full rotation count. A plain shaft eases coupling to gearboxes, and a radial shaft seal helps limit dust, coolant, and lubricant ingress. The front flange is plain and accepts fixtures without additional keys. The housing follows the standard MDD enclosure layout, and the assembly has a shaft end only on side A.
