Product Description:

The MDD090C-N-020-N2L-130PB2 is a brushless AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Used with digital drive controllers, it converts commanded inverter current into controlled shaft rotation for positioning and speed regulation in automated machinery. The brushless design eliminates mechanical commutation inside the motor, which helps support smooth operation during repeated duty cycles. This arrangement fits feed axes, transfer systems, and similar equipment that depends on closed-loop motion. Its mechanical interface allows direct coupling to gearboxes or machine elements in assembly and handling applications.

The motor develops a continuous standstill torque of 10.4 Nm, which provides steady holding force while the shaft remains energized. Under rated conditions, the rotor reaches a nominal speed of 2000 rpm, making it suitable for medium-inertia positioning tasks. Mounting is centered by a 130 mm pilot diameter that helps keep the motor aligned with the driven mechanism. Power and feedback lines exit at the rear because the connection hardware is located on side B and uses a keyed connector. Standard balancing helps reduce residual vibration during repeated cycles. The C length code corresponds to the active stack depth within the 090 frame size, and the single drive-end shaft avoids unnecessary overhang on the opposite side.

For holding position when power is removed, the motor is supplied with a blocking brake. That brake provides a clamping torque of 11.0 Nm, which helps maintain axis position on vertical or load-sensitive applications. Position data is provided through Digital servo feedback (DSF), allowing the controller to monitor rotor movement accurately during closed-loop operation. This feedback channel also supports stable commutation and speed correction while the axis is in motion. The output shaft uses a keyway, and a shaft seal helps keep contaminants out while limiting lubricant escape.
