Product Description:

The MDD090B-N-040-N2L-130PA1 is an AC synchronous servo motor built by Bosch Rexroth Indramat and part of the MDD Synchronous Motors series. Designed for use with digital drive controllers, it supplies closed-loop rotary motion for automated axes that require repeatable speed and position control. Standard balancing and the compact housing support installation in common machine frames, while the lack of a side B shaft end helps keep the overall package short for tight mounting spaces.

The mechanical interface uses a centering diameter of 130 mm, which helps align the motor flange with the driven assembly and reduce runout. At standstill, the motor can deliver a continuous torque of 7.2 Nm, providing steady holding capability without excessive heating. During operation, it reaches a nominal speed of 4000 rpm, which suits fast axis movement in digitally controlled systems. An integrated blocking brake provides 6.5 Nm of static holding torque so the axis can remain secured when power is removed. Position and velocity signals are returned through digital servo feedback, allowing accurate regulation by the connected drive.

Electrical and signal conductors exit on side A through a keyed connector, which keeps cable orientation consistent when several motors are installed in the same machine area. The motor uses frame size 090, making it compatible with applications already arranged around that mechanical envelope. A factory-fitted shaft seal helps protect the internal bearings from lubricants and cutting fluids found in typical industrial environments. Torque is transmitted through a keyway shaft, which provides a positive mechanical connection without depending only on clamping friction. The single-ended shaft arrangement also reduces the space needed behind the motor when it is mounted close to adjacent components.
