MDD021B-N-100-N2K-032MA0
The MDD021B-N-100-N2K-032MA0 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat for its MDD Synchronous Motors series. Purpose-built as a motor for digital drive controllers, it translates precisely timed current pulses into rapid rotary motion required by pick-and-place heads, miniature index tables, and laboratory automation stations. A size 021 frame with the B length code keeps the package short, and its integrated feedback supports accurate position monitoring during operation. Its compact format suits machine layouts where adjacent components leave limited clearance for larger servo assemblies.
Under continuous stall conditions, the rotor sustains 0.30 Nm of torque, permitting static load holding without thermal overload. When acceleration is demanded, the shaft can reach the rated speed of 10000 rpm, making the unit suitable for high-throughput equipment. A centering pilot of 32 mm eases concentric alignment to gearheads or flanges, and all cabling exits on side A to keep service zones on one face of the machine. Position and velocity are monitored through resolver feedback, allowing the controller to regulate motion smoothly at both high and very low speeds. Power and signal conductors terminate in a single plug-in connector that simplifies installation.
The rotor is trimmed to Standard balancing quality, so vibration remains low throughout the wide speed range. A cast aluminum body with Standard housing classification conducts heat away while resisting industrial contaminants. The drive-side shaft uses a keyway for positive torque transfer and has a single extension to save space on side B. The motor is supplied without a blocking brake, so stationary holding must be provided externally. Because the design omits a shaft seal, external protection is recommended if the motor is exposed to liquids or fine dust.
