Product Description:

The MDD090B-N-040-N2L-110PA1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers that need accurate positioning and stable velocity control on automated axes. The motor supplies rotary motion for assembly cells, packaging lines, and similar equipment where repeatable response is important. Its synchronous design supports rapid changes in commanded speed and position when it is paired with a compatible servo drive.

At standstill, the rotor can deliver 7.2 Nm of continuous torque, which helps the axis support static loads during low-speed operation. During motion, it reaches a nominal speed of 4000 rpm for fast-cycle applications. When power is removed, a blocking brake provides up to 6.5 Nm of holding torque to help keep the axis in place. The centering diameter of 110 mm supports accurate alignment with gearboxes and mounting adapters. Size code 090 identifies the stator frame outline, and the shaft has a keyway for standard keyed couplings. The housing is supplied in a standard grade, and the shaft seal helps limit lubricant migration along the output shaft. This combination supports applications that need quick travel during operation and secure holding when the axis stops.

Cabling enters on Side A, and all power and feedback conductors terminate through a sealed connector. Position data is returned by Digital servo feedback (DSF), enabling high-resolution closed-loop control without additional sensors. The motor length code is B, and the shaft is provided only on side A so the rear of the motor can remain clear for adjacent hardware. Keeping the connections on one side can make cable routing easier in compact machine layouts. Internal balancing keeps vibration within ISO limits, and the shaft seal supports mild washdown environments. This arrangement helps the motor fit crowded machine spaces without changing the cable exit direction.
