Product Description:

The MDD090B-N-030-N2L-130PA2 synchronous motor is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Intended for use with digital drive controllers, it converts controlled electrical power into rotary motion for positioning and velocity tasks in automated machinery. The motor uses the 090 frame size, has standard rotor balancing, and has a standard housing style, making it suitable for general-purpose machine axes without additional mechanical changes. This arrangement supports repeatable motion on axes that require stable speed control and accurate positioning.

In continuous duty, the motor supplies 7.2 Nm of standstill torque and reaches a nominal speed of 3000 rpm when driven at rated current. An integrated blocking brake secures the shaft with a holding capacity of 11.0 Nm during power-off conditions. Precise mechanical centering is provided by a 130 mm centering diameter that aligns the motor to the mounting pilot. Rotor position is monitored through Digital servo feedback (DSF), enabling the controller to close high-resolution speed and position loops. This feedback helps the drive respond quickly to load changes during positioning and speed regulation. The B length code indicates the active stack height, and the standard housing works with an internal shaft seal to help keep contaminants away from internal components.

Power, feedback, and brake conductors exit toward the machine base because the terminations are located on Side A and use a plug-in Connector. This cable exit direction can simplify routing when the motor is mounted near upper guards or other nearby machine structures. Torque is transmitted through a keyway, and a shaft seal helps block fluid ingress along the rotating member. The motor omits a secondary shaft on side B, which leaves the non-drive end clear for surrounding machine components and helps keep the external layout compact.
