Product Description:

The MDD090C-N-030-N2M-130PB0 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. Designed for pairing with digital drive controllers, this motor converts controlled stator currents into precise rotary movement for indexing tables, packaging machinery, and similar automation tasks. Its integrated position-feedback chain helps the controller maintain accurate speed and position during repeated starts, stops, and short positioning moves. This makes the unit suitable for axes that must accelerate cleanly, dwell briefly, and return to the commanded position without noticeable drift.

Mechanical mounting is guided by a centering feature that measures 130 mm, allowing the housing to seat squarely in a drive train. Power and feedback conductors exit on side B, and the built-in connector interface allows pre-terminated cables to be attached without hardwiring. This layout keeps the electrical connection compact at the motor housing and supports orderly cable routing in enclosed machinery. Under stall conditions, the electromagnetic design sustains 10.4 Nm of continuous torque, supporting static loads until motion resumes. The motor is supplied without a blocking brake, so holding force must be provided by the drive or an external mechanical lock when power is removed. A shaft seal helps prevent lubricant migration, and the standard keyway end mates with couplings while the opposite end remains closed rather than using a second shaft extension.

Rotor position is captured by an integrated multi-turn absolute encoder, and its signals are routed through the motor’s digital servo feedback (DSF) channel for immediate use by the controller. Because the encoder stores absolute position over multiple turns, the control system can recover shaft location after power cycles without relying on a homing move in many applications. Closed-loop regulation holds speed at a rated 3000 rpm, which suits medium-inertia loads that need frequent starts and stops. The motor uses a keyway shaft configuration, while length code C keeps the overall stack height moderate for installations with limited axial space. The standard housing and balancing class also help limit vibration transmitted to adjacent machine elements.
