MDD021A-N-100-N2G-032MB0
The MDD021A-N-100-N2G-032MB0 is an MDD series synchronous motor produced by Bosch Rexroth Indramat. As a servo motor for digital drive controllers, it provides closed-loop position and speed control in space-restricted automation stations such as pick-and-place arms and miniature gantries. Its compact size comes from frame code 021 and the short A length, which lets the motor sit close to the driven load and helps reduce coupling compliance. This layout suits small handling systems where responsive motion and limited installation space are both important.
The rotor can hold a load at rest with 0.15 Nm of continuous standstill torque, and it reaches commanded speeds up to 10,000 rpm for rapid cycle moves. A centering pilot of 32 mm helps with concentric mounting and keeps runout low during operation. Rotary position is returned to the drive through resolver feedback, which supplies rotor angle information for closed-loop control across the operating range. This speed capability supports short indexing moves and fast return strokes in compact machinery. Power and signal cabling attach through a single industrial connector, which keeps the interface compact and reduces the number of separate connection points.
The motor is supplied without a blocking brake and without a shaft seal, which reduces friction and rotational inertia. Any static holding function must be provided by the drive or by the surrounding machine mechanism. All connections exit on Side B of the housing, which can simplify cable routing in narrow machine frames and keeps conductors away from rotating transmission parts. The shaft uses a keyway for positive torque transfer to keyed hubs or pulleys. Standard dynamic balancing and the basic enclosure format allow installation in compact assemblies where surrounding machine parts provide the needed protection.
