Product Description:

Bosch Rexroth Indramat produces the MDD093C-N-020-N2M-130PB2 as part of the MDD Synchronous Motors series. The unit is a permanent-magnet AC motor intended for digital drive controllers, where it supplies coordinated torque and velocity to automated axes in packaging, printing, and material-handling equipment. It connects directly to compatible servo inverters and supports position-controlled operation without external gearing. This arrangement allows stable closed-loop motion on axes that must start, stop, and follow repeated position commands through long production cycles.

The mechanical envelope uses a centering diameter of 130 mm, which aligns the flange accurately with machine frames. Power and feedback conductors exit on Side B, and the motor uses a factory-installed connector that simplifies wiring while helping preserve enclosure sealing. A blocking brake provides 22 Nm of holding torque, so vertical or suspended loads can remain stationary when power is removed. The rotor reaches a nominal speed of 2000 rpm, which suits low-noise applications that require smooth motion rather than high spindle speed. The cast aluminum housing uses standard cooling fins, a shaft seal helps limit dust or oil ingress at the output journal, and the shaft is supplied without a rear extension.

An integrated multi-turn absolute encoder transmits precise rotor position data to the drive, and the signal path follows digital servo feedback (DSF) conventions for high-resolution commutation. The motor’s frame size of 093 and length code C increase continuous torque without enlarging the mounting pitch, which helps preserve compact machine layouts. Torque is delivered through a keyway shaft, so couplings or pulleys can be locked mechanically without relying only on interference fits. Standard housing finish and dynamic balancing support general-purpose automation duty during repeated indexing and speed-controlled motion.
