Product Description:
Bosch Rexroth Indramat manufactures the MDD090A-N-030-N2L-130PB2 as part of the MDD Synchronous Motors series. This AC servo motor is intended for use with digital drive controllers, where it converts regulated current into synchronous rotary motion for positioning tables, pick-and-place axes, and other coordinated automation tasks. In typical automation cells, this allows the axis to respond to commanded acceleration, deceleration, and holding requirements with stable synchronous behavior. The motor uses the MDD platform, giving it a standardized mechanical package for integration into multi-axis systems that require accurate speed and position control.
The centering flange measures 130 mm, allowing the motor to seat directly against compatible gearboxes or mounting plates. Power and feedback leads exit on side B, and the connector interface provides a compact electrical connection point. This cable arrangement can simplify routing when the motor is mounted with the flange facing the driven load. At standstill, the stator can deliver 3.7 Nm of continuous torque to support steady loaded operation while the drive remains enabled. When supplied at rated frequency, the motor reaches 3000 rpm. That speed suits many servo applications that need a broad operating range without a large motor envelope. The A-length housing helps keep the motor short, and heat is removed through natural convection. A single shaft end is provided on the drive side, and a shaft seal helps keep coolant and debris out of the bearing cavity.
An integrated holding brake supplies 11.0 Nm of static torque, so the shaft can remain secured when supply power is removed. Position data is transmitted through digital servo feedback, allowing the controller to maintain closed-loop operation without an external encoder. This arrangement supports precise commutation and position monitoring during motion. The motor has a frame size of 090, which matches the mechanical envelope used for this model. Torque is transmitted through a keyway shaft to support repeatable coupling to pulleys or pinions under changing load. The keyed output is intended for positive mechanical engagement with standard transmission elements. The rotor is balanced to a standard grade for general industrial motion applications.
