Product Description:

Bosch Rexroth Indramat manufactures the MDD090B-N-030-N2L-130PB2 within the MDD Synchronous Motors series. The unit is a brushless AC servo motor intended for digital drive controllers where precise torque production and feedback are required to synchronize motion in automated machining centers, transfer lines, and pick-and-place modules. It converts regulated electrical input into controlled rotary motion for feed axes and positioning tasks that require repeatable response. Its brushless design also avoids commutator wear and supports consistent operation in applications with frequent start-stop cycles.

The motor’s nominal speed is 3000 rpm, so a matching inverter can command up to that speed without field weakening. At standstill, it develops 7.2 Nm of continuous torque, allowing static load support while position is held. A centering flange diameter of 130 mm provides axial alignment to gearboxes or mounting plates, and the rotor-shaft mass is balanced to a standard grade to help limit vibration during operation. Power and feedback leads exit from side B because the connection hardware is located there, and a sealed circular connector simplifies cable changes. The housing is supplied in a standard configuration, and length code B identifies the electromagnetic stack height used for this motor version.

A blocking brake delivers 11.0 Nm of holding torque so vertical or suspended axes remain stationary when power is removed. The motor includes a shaft seal that helps prevent coolant or cutting fluid from entering the front bearing cavity. Its output shaft is machined with a keyway for secure coupling to pulleys or helical gears without relying on friction alone. Position information is returned through Digital servo feedback (DSF), enabling the drive to correct speed and position deviations in real time. The motor also uses a single-ended shaft in a standard housing, which suits compact servo installations with direct coupling to machine elements.
