Product Description:
The MDD090A-N-030-N2M-110GB1 synchronous servo motor is manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it drives machine axes that demand closed-loop speed and position control. The design uses the compact A-length stator, reducing overall depth so it fits inside confined automation cells. A standard housing and a carefully balanced rotor minimize vibration at high speed, helping maintain accuracy during repeated start-stop sequences. This layout suits indexing, transfer, and packaging duties where stable motion and repeatable positioning are important.
At its rated operating point, the motor turns at 3000 rpm, a speed that matches drive regulators used on medium-inertia axes in pick-and-place units and packaging machines. In standstill conditions, it can deliver 3.7 Nm of continuous torque, giving the controller a useful stall margin for tensioning or indexing duties. When power is removed, the integrated blocking brake locks the rotor with 6.5 Nm of static torque to prevent load drift on vertical shafts. The centering flange diameter of 110 mm ensures concentric alignment to the machine frame, which helps limit runout during coupling. All power and feedback terminations point toward side B, and the single circular connector streamlines cable routing while keeping the opposite face clear for mounting hardware. This arrangement also helps when the motor is installed close to adjacent mechanical components.
Position data is generated by the integrated multi-turn absolute encoder, and the drive reads these signals through Digital servo feedback (DSF) so full revolutions are tracked without homing after power-up. A factory-installed shaft seal helps protect the bearing area from coolant splash and light contamination. The motor adopts size code 090, pairing a moderate stator diameter with the A-length core to keep inertia compatible with small gearboxes and direct-coupled axes. The plain shaft is delivered without a secondary extension on side B, and the connector layout allows straightforward integration into IP-rated enclosures. The feedback system also supports accurate position retention during normal machine restarts.
