Product Description:

The MDD090B-N-040-N2L-130GR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed to pair with digital drive controllers, it supplies commanded torque and speed for coordinated axes in automated assembly lines, material-handling gantries, and general motion platforms. The motor uses the 090 frame class with B length, providing a mid-range package for machines that need a balance of compact size, output, and dynamic response. Its synchronous design supports precise closed-loop motion where repeatable speed control and accurate positioning are required during frequent acceleration and deceleration.

The motor reaches a nominal speed of 4000 rpm, which supports fast indexing while staying within its thermal operating range during normal use. It can maintain a continuous torque of 7.2 Nm for steady running loads, making it suitable for axes that need consistent output rather than brief overload only. Position and velocity signals are returned through digital servo feedback (DSF), allowing the controller to close high-bandwidth loops without a separate external encoder. For installation, the power and feedback connectors use a connection on the right side, which can simplify cable routing along the machine frame. A 130 mm centering diameter on the flange helps align the motor accurately with the mounting surface or gearbox.

When the axis must remain stationary after power is removed, the brake provides 6.5 Nm holding torque to resist back-driving under parked conditions. Mechanical output is transmitted through a plain shaft, and an integrated shaft seal helps limit contaminant entry and lubricant escape at the shaft interface. The rotor uses standard balancing, which keeps vibration within normal industrial limits and supports smooth operation on typical machine structures. This arrangement suits couplings, pulleys, and other driven elements that rely on stable rotation and straightforward mechanical alignment.
