Product Description:

The MDD090B-N-020-N2M-130PR1 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it supplies regulated rotary motion to automated axes in assembly lines, packaging machinery, and material-handling equipment. This type of motor is suited to applications that require controlled acceleration, stable speed, and accurate positioning during repeated cycles. The motor has a single-ended shaft, so only the drive end projects from the housing, which helps simplify coupling to the driven mechanism.

At a nominal speed of 2000 rpm, the motor provides a continuous standstill torque of 7.2 Nm, which supports holding force at low-speed operation and controlled motion during indexing tasks. A centering diameter of 130 mm aligns the housing on the machine mounting face. Power and feedback conductors exit on the right side, and the motor uses a factory-installed connector interface for electrical connection. Position and velocity are reported through digital servo feedback (DSF), allowing the paired controller to monitor rotor movement continuously and correct deviations as load conditions change.

An integrated blocking brake rated at 6.5 Nm secures the shaft when power is removed, which is useful when the axis must remain in place at standstill. The output shaft uses a keyway, and a shaft seal helps keep lubricant inside the housing while reducing contaminant entry. With frame size 090, the motor fits a moderate installation footprint. The standard housing uses length code B, which sets the axial length of the motor body. An integrated multiturn absolute encoder retains position over multiple revolutions, allowing the control system to recover shaft position after a power loss without depending on a full reference run.
