MDD021A-N-100-N2K-032FA0
The MDD021A-N-100-N2K-032FA0 is a compact synchronous servo motor produced by Bosch Rexroth Indramat in the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts commanded electrical input into precise rotary motion for pick-and-place heads, miniature conveyors, and electronics assembly tooling. Its standardized housing and connector layout suit compact automation equipment where installation space is limited. The plain output shaft supports couplings or belt pulleys without the added width of a keyed connection.
It reaches a nominal speed of 10000 rpm, allowing very short cycle times when the axis must accelerate and stop repeatedly. At standstill, the electromagnetic system can deliver 0.15 Nm of continuous torque, which suits light-duty holding and positioning tasks. Accurate alignment is supported by a 32 mm centering diameter that fits standard mounting pilots. Power and feedback conductors exit on Side A through a connector, which helps keep cable routing orderly in shallow cabinets and densely packed mechanisms. The shaft is supplied without a secondary end, which keeps the package compact and reduces rotating mass.
Signal quality is maintained by resolver feedback, while an integrated absolute encoder also tracks rotor position for fine low-speed control and immediate position availability at startup. The motor uses the motor size 021 envelope with length code A, making it suitable for axes where available mounting space is very limited. Its rotating members use standard balancing to help limit vibration at high speed and support smooth operation in precision assemblies. The motor is supplied without a blocking brake, so parked loads must be held by the drive or an external device. It also has no shaft seal, which reduces running friction in clean, enclosure-mounted applications.
