Product Description:
The MDD090A-N-030-N2L-110GA0 is a synchronous servo motor built by Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is designed for pairing with digital drive controllers in automated production cells. In closed-loop motion systems, the unit converts regulated electrical power into rotary movement, enabling precise positioning and speed control for packaging lines, handling robots, and general material-processing equipment. Because the motor works with a digital controller, current, speed, and position loops can be coordinated by the drive for accurate axis response. This makes the unit suitable for machinery that must follow repeated motion profiles with stable speed regulation.
Mechanical dimensions follow the 90 mm frame format; the size code 090 identifies the stator outside diameter, while the centering diameter is 110 mm for repeatable flange alignment. The centering diameter helps seat the motor accurately against the machine flange, supporting concentric alignment between the motor and the driven load. At standstill, the electromagnetic system can deliver 3.7 Nm of continuous torque without overheating, and when powered by a matched inverter the rotor reaches a nominal speed of 3000 rpm. Electrical power and feedback conductors exit from Side A of the housing, and the power interface uses a keyed Connector for a secure cable connection. Motor length code A indicates the shortest stack in this frame, which helps reduce installed depth in compact machines.
Control precision is obtained from the integrated Digital servo feedback encoder that transmits absolute rotor position data to the drive controller. That feedback channel supports commutation and speed regulation without a separate external measuring device. The motor is supplied without a blocking brake, so axes that must remain fixed at standstill need external holding by the drive or by machine mechanics. The plain output spindle follows the standard shaft pattern and is equipped with a shaft seal, which helps protect the bearing area when dust or light coolant mist is present. The housing uses standard construction for regular industrial duty.
