Product Description:

The MDD090C-N-040-N2L-130GR2 synchronous motor is produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts regulated current from the servo drive into rotary motion for positioning or speed-controlled axes in automated machinery. It integrates with digital servo systems to supply repeatable torque for tasks such as packaging, printing, and material handling. This operating role makes it suitable for indexing stations, feed axes, and transfer mechanisms that require repeatable motion over long production runs and frequent start-stop cycles throughout production.

It delivers a continuous standstill torque of 10.4 Nm, allowing closed-loop holding force without overheating when the shaft is motionless. During operation, the rotor can reach a nominal speed of 4000 rpm, a rating that balances dynamic response and bearing life for mid-frame machines. Position data are returned through Digital servo feedback (DSF), so the drive can command precise increments with rapid correction. Power and feedback conductors exit on the right because the unit uses a right-side connection. It also uses a connector interface, which keeps the wiring point compact and makes cable attachment straightforward. The motor uses frame size 090 and frame length C, which helps it fit common servo mounting spaces.

Its mechanical fitment centers on a 130 mm pilot diameter that aligns the flange to gearboxes or machine mounts. An integrated blocking brake applies 11.0 Nm of holding torque to secure vertical loads when power is removed. The shaft is machined as a plain shaft and is protected by a shaft seal, keeping lubrication inside the housing and contaminants out. With a standard housing and a single-ended shaft arrangement that has no side-B extension, the motor fits compact assemblies without adding length at the rear. This layout also leaves more clearance for adjacent machine parts and cable routing around the drive end.
