Product Description:

The MDD090C-N-030-N2M-130GA0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it provides rotary motion and position feedback to automation axes that require coordinated, closed-loop control. This unit integrates directly into modular drive cabinets where space is limited and where electronic synchronization between multiple motor shafts is critical.

The motor delivers a continuous standstill torque of 10.4 Nm, allowing it to hold or slowly move loads without overheating when current is limited to its rated value. A nominal speed of 3000 rpm is the maximum steady-state shaft velocity under rated voltage and frequency. Mechanical alignment is aided by a centering diameter of 130 mm, which matches standard flange openings and keeps the stator concentric to the driven equipment. Power and feedback leads exit on Side A, so cable trays can be planned on one face of the cabinet. The frame belongs to motor size 090, which indicates the stator outside diameter and helps with the selection of compatible gearboxes, couplings, and mounting hardware. Standard balancing minimizes vibration at high speed, and the housing is supplied in the standard style for this series.

An integrated multiturn absolute encoder provides position data over multiple revolutions, and the digital servo feedback interface exchanges that data with the controller in real time. The motor is supplied without a blocking brake, so any static holding force must be provided by the drive or external mechanics. To keep lubricant inside and contaminants outside, the shaft is equipped with a shaft seal. The rotor ends in a plain shaft that accepts clamp or keyless couplings, and the motor uses a standard single-shaft configuration without a side-B extension. The length code C gives this model a moderate axial dimension suitable for compact machine frames.
