Product Description:

The MDD090C-N-040-N2L-130PB2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts electrical command signals into controlled rotary motion for positioning tables, feeders, and similar automation axes. The motor uses the 090 frame with a standard housing, standard rotor balancing, and length code C, so it fits installations built for the same mechanical envelope. This type of motor is commonly used where smooth response and accurate closed-loop motion are required during repeated start-and-stop cycles.

The motor centers on a 130 mm pilot, allowing repeatable alignment to gearboxes or machine plates. Power and feedback cables exit on side B through a sealed connector, which helps keep wiring organized when the drive is mounted behind the machine. During continuous stall conditions, the motor supplies 10.4 Nm of torque, and its windings support a nominal mechanical speed of 4000 rpm. The housing is unventilated, so heat is transferred through the mounted machine structure rather than by a separate fan, and the front of the motor remains clear for coupling to the driven mechanism.

An integrated blocking brake develops 11.0 Nm to hold vertical or static loads when power is removed. Feedback to the drive is provided by digital servo feedback (DSF), which supports accurate position control without a separate external encoder. Output torque is transmitted through a keyed shaft fitted with a shaft seal, helping limit lubricant migration and the ingress of coolant. The motor has no shaft extension on side B, which keeps the rear of the housing simpler and reduces the required installation space. Because the brake is intended for holding, controlled motion during operation is managed by the connected drive.
