Product Description:

The MDD090C-N-020-N2M-110GR0 synchronous servo motor is manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies tightly regulated rotary motion for automated packaging lines, robotic joints, and material-handling axes. Its 090 frame size keeps the installation envelope small, which helps it fit compact machine modules while still supporting steady industrial duty.

At standstill, the rotor delivers a continuous torque of 10.4 Nm, giving machinery enough holding force without an external brake. The motor can accelerate loads up to its nominal speed of 2000 rpm while remaining within the thermal limits of the standard housing. A centering diameter of 110 mm aligns the motor precisely on adapter plates, and factory balancing to a standard grade helps keep vibration low during continuous operation. Electrical power, signal, and grounding conductors exit on the right side through a sealed connector, which helps cable routing in narrow cabinets or crowded machine frames. The unit is supplied without a blocking brake, so static holding must come from the drive or an external mechanical device.

Position data comes from an integrated multiturn absolute encoder, and the controller interprets it through digital servo feedback (DSF) for high-resolution closed-loop control. The motor body uses length code C, pairing a longer stator stack with the 090 lamination to increase continuous power without increasing width. A plain shaft transfers torque directly to couplings, and a molded shaft seal helps limit fluid ingress along that journal. The shaft is present only on the drive side, which simplifies coupling arrangements where no rear shaft extension is required. This layout supports accurate motion in servo axes that depend on consistent feedback and stable mechanical alignment.
