Product Description:

The MDD090A-N-030-N2M-130GL1 is a synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed as a drive element for digital drive controllers, the unit converts drive current into rotary motion for positioning tasks in automated machinery. Its compact housing supports integration into multi-axis assemblies on packaging lines, pick-and-place gantries, and tooling systems where closed-loop velocity and position regulation are required. Because it is intended for closed-loop servo operation, the motor works well in applications that need smooth low-speed control and accurate repositioning during repeated cycle changes.

For continuous operation, the motor can deliver 3.7 Nm of torque while the rotor is held stationary. During motion, it reaches a base speed of 3000 rpm, which supports steady speed control across common servo applications. Mechanical alignment to adjacent gearboxes is simplified by its 130 mm centering diameter, and a built-in blocking brake supplies 6.5 Nm of holding torque to keep a vertical axis from drifting when power is removed. All power and feedback conductors exit through a left-side connection, which helps keep cable routing clear of moving machine parts in right-hand installations. In feed axes and lift mechanisms, these characteristics help the drive hold load at rest and restart without unwanted rollback.

To protect internal bearings from contaminants, the design includes a shaft seal, and the motor uses a single plain shaft without a second shaft end to reduce overall length. Position data is produced by an integrated multiturn absolute encoder, and those signals are transmitted as digital servo feedback so the controller can retain rotor position information after a power cycle. The motor uses the 090 frame size and standard mechanical balancing for this platform. Absolute position information reduces the need for reference searches at startup, which is helpful on machines that resume operation after short power interruptions. Length code A and the plain-shaft layout support couplings that benefit from compact motor dimensions and responsive acceleration.
