MDD021A-N-100-N2K-032MA0
The MDD021A-N-100-N2K-032MA0 is a compact AC synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers and provides rapid rotary positioning and speed regulation in automated assembly stations, small pick-and-place units, and laboratory handling modules. Its compact format makes it suitable for motion axes where installation space is limited but repeatable servo response is still required.
This model develops a continuous standstill torque of 0.15 Nm, allowing light loads to be held or moved without overheating when the rotor is locked. Its winding supports a nominal speed of 10000 rpm, so high cycle rates are possible when it is paired with a compatible drive. The front flange has a centering diameter of 32 mm, which provides an accurate locating fit for the machine frame or gearhead. The motor length code A indicates the shortest housing version in this family, which helps reduce the required installation depth. Power is transmitted through a shaft with a keyway, giving a positive mechanical connection to pulleys or couplings. Standard dynamic balancing helps maintain smooth operation for small-frame servo applications, and the compact housing supports use in tightly arranged machine assemblies.
Cables are routed on Side A through a single circular connector, which helps keep wiring access straightforward in compact panels and machine modules. Position data is returned by resolver feedback, and an integrated absolute encoder supplies multi-turn information for reference-free homing. The design is delivered without a blocking brake, so an external holding device is needed when power-off load retention is required. Because there is no shaft seal, the motor should be installed where fluid ingress is not expected, and the housing uses the standard ventilated style. The shaft is supplied without a side-B extension, which helps conserve length and reduces inertial load on miniature mechanisms.
