Product Description:

The MDD090A-N-040-N2M-110PR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Designed for digital drive controllers, it supplies closed-loop mechanical power to indexing tables, packaging axes, and other industrial automation tasks that rely on precise velocity and position control. The motor works with digital control loops to support repeatable positioning, smooth acceleration, and stable operation when the load changes during a motion cycle.

This model produces a continuous standstill torque of 3.7 Nm, giving the axis enough holding force for low-speed tasks without overheating. Its nominal operating speed is rated at 4000 rpm, so it suits high-cycle production lines that need quick acceleration and stable speed control. When power is removed, the integrated brake can apply up to 6.5 Nm of torque for secure load retention. Mechanical alignment is simplified by a centering diameter of 110 mm, while all power and feedback conductors exit on the right side through a sealed connector, which helps keep cable routing organized at the machine interface. Standard dynamic balancing minimizes vibration during operation, and length code A indicates the shortest stack in this frame, helping the motor fit installations with restricted axial space.

Motion feedback is generated by a digital servo feedback system that combines commutation data with absolute position information from a multi-turn absolute encoder, allowing the controller to retain position information across multiple revolutions. To protect internal bearings, a shaft seal is fitted at the single keyway shaft, and the shaft end follows the standard pattern without an extension on side B. Frame size 090 keeps the overall footprint compact, and the motor uses a standard industrial connector for its power and feedback connections. The compact frame helps the motor fit machine layouts where space near the axis is limited.
