Product Description:

The MDD090A-N-040-N2L-130GB0 is a permanent-magnet AC servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for digital drive controllers, it converts stator current into regulated rotary motion for tooling, conveyor rollers, and vision stages in automated equipment. Integrated electronic feedback lets the drive maintain tight control of speed and position as load conditions change during normal operation. This arrangement supports repeatable motion on axes that need accurate starts, stops, and short positioning moves.

The motor delivers a continuous standstill torque of 3.7 Nm, allowing lightly loaded axes to remain at hold points without excessive heating. Under rated excitation, the rotor reaches 4000 rpm, giving the axis a useful range for rapid indexing and short transfer moves. Position data is returned through digital servo feedback, so the controller can correct speed and angle with fine resolution. Flange installation is simplified by a 130 mm centering diameter that helps align the motor on the machine face. Power and feedback plugs are located on side B, and the closed housing carries heat into the surrounding airflow path.

Rotor mass is trimmed and balanced to the standard grade, which helps limit vibration when the drive couples to the load through a plain shaft. The working journal is protected by a shaft seal, and the opposite end remains blank under the standard shaft-end arrangement. Cables attach through a keyed connector, which keeps the electrical interface compact and helps maintain correct orientation during installation. The motor size is 090 with length code A, so the housing stays compact enough for machines with limited mounting space. Because the motor is supplied without a holding brake, a vertical axis must rely on external clamping or drive-produced torque to remain in position when power is removed.
