Product Description:
The MDD090A-N-040-N2L-130GB1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is installed on machine axes where closed-loop speed and position control are required. The 090 frame diameter and compact A-length stator allow integration into packaging stations, pick-and-place gantries, and light machining centers, while the standard housing supports installation where space around the axis is limited. Its compact form also helps the motor fit into layouts that need short overall motor length without sacrificing precise motion control.
Its nominal shaft speed reaches 4000 rpm, so the rotor can follow high-frequency command changes without mechanical overshoot when paired with a matched drive. At standstill, the motor delivers a continuous torque of 3.7 Nm, giving sufficient holding force for indexing tables before the brake engages. Power and feedback conductors exit on the rear face identified as Side B, and the single circular Connector keeps cable routing compact at the rear of the motor. Rotor position is reported through Digital servo feedback (DSF), enabling the controller to correct small velocity deviations during each control cycle and maintain synchronized axis movement. This feedback arrangement also supports stable speed regulation during frequent starts, stops, and short positioning moves.
The built-in blocking brake secures the load with 6.5 Nm of static torque during power-off conditions. Precision mounting is assisted by a centering flange that measures 130 mm in diameter, and vibration is limited by the motor’s standard balancing grade. A plain output shaft is protected by a shaft seal that helps keep lubricants inside and contaminants out, while the absence of a second shaft end leaves additional space for couplings or belt pulleys on related machine elements. This single-ended shaft arrangement also leaves the non-drive side less crowded, which can simplify adjacent mechanical layout.
