Product Description:

The MDD090A-N-040-N2L-130PL0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for use with digital drive controllers, it provides closed-loop torque and speed control for indexing tables, packaging axes, and other automation stages that require compact rotary actuation. Integrated electronic feedback allows the connected drive to adjust current in real time so mechanical motion follows programmed profiles with stable tracking during acceleration, deceleration, and direction changes. This arrangement supports precise positioning behavior in machines where repeatable motion and responsive control are both required during continuous industrial operation.

At standstill, the motor can deliver 3.7 Nm, enabling stable force on static loads while thermal limits are observed. When accelerated by the inverter, the rotor reaches a nominal speed of 4000 rpm, which suits high-cycle machinery that requires rapid reversals and short movement times. The centering shoulder measures 130 mm, setting the datum for flange alignment and helping maintain concentricity with gearboxes or belt pulleys. Power and feedback cabling exit on the left side, which can simplify routing when the machine layout places the drive cabinet on that side. Commutation and position data are transmitted through digital servo feedback, allowing the drive to regulate motor current precisely and maintain smooth motion across changing load conditions.

The motor body uses a standard housing that fits common installation arrangements in the frame family. The output shaft includes a keyway for positive torque transmission to a mating coupling element, and all external connections are made through a sealed connector so wiring can be removed without opening a terminal chamber. Length designation A indicates the shortest stator stack in the 090 frame, which helps keep rotor inertia low for responsive axis behavior. A shaft seal helps block oil or coolant ingress during operation, and the unit is supplied without a holding brake to avoid adding unnecessary rotating mass. Standard dynamic balancing supports smooth rotation, and the single-ended shaft layout on side A keeps the mechanical arrangement straightforward for compact machine designs.
