Product Description:

The MDD090A-N-020-N2L-110GL2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded current into precise rotary motion for industrial positioning tasks. The motor uses the 090 frame size and short A length code, giving it a compact form for space-limited machinery. A standard housing and standard dynamic balancing support straightforward mounting, and the shaft is provided only on side A while side B remains closed. That layout helps the motor fit compact feed axes, indexing stations, and other machinery where installation depth is limited.

At rated supply, the motor reaches a nominal speed of 2000 rpm, allowing direct coupling to gear stages or loads that operate in the lower-speed range. During standstill, the electromagnetic system can deliver 3.7 Nm of continuous torque for stable holding or low-speed feed. The mounting flange includes a 110 mm centering diameter that helps align the stator with the driven machine frame. Power and feedback are routed through a connector that faces left, so cable runs can stay on the same side as adjacent axes. This layout also reduces cable crossover in dense machine assemblies.

For emergency or power-off conditions, the integrated blocking brake can maintain up to 11.0 Nm of static torque to help prevent vertical loads from drifting. Position data is returned through digital servo feedback (DSF), allowing closed-loop control inside the drive. The output uses a plain shaft, and a shaft seal helps keep lubricant in place while limiting contaminant entry into the bearing area. The brake engages when power is removed, which helps the axis remain stationary during stops. This arrangement is suitable for installations exposed to coolant splash or frequent cleaning.
