MDD021B-N-100-N2G-032FA0
The MDD021B-N-100-N2G-032FA0 is a compact synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers in automated machinery that requires rapid positioning and stable speed regulation. The compact frame and fast response make it well suited for pick-and-place units, small gantries, and other axes where low moving mass helps support quick directional changes and precise motion control.
The motor provides a continuous standstill torque of 0.30 Nm, which suits low-inertia loads that must be held without excessive current demand. Its maximum operating speed is 10000 rpm, allowing the motor to support fast cycling on light mechanical systems and compact spindle-style duties. A centering diameter of 32 mm helps align the motor accurately on the machine plate for stable coupling. Rotor position is supplied through resolver feedback, which gives the drive a continuous angle signal and resists electrical noise common in industrial cabinets. The output uses a plain shaft, so torque is transferred through collets or flexible couplings rather than a keyed connection.
Cabling exits on Side A, which can simplify routing when the motor is mounted with its flange toward the driven assembly. Power and feedback conductors share a sealed connector, reducing the number of separate terminations and helping maintain contact integrity under vibration. The housing uses motor size 021, and the active stack uses motor length code B, which keeps the body short for installations with limited space. The motor is supplied without an internal holding brake and without a shaft seal, so any required holding force or contamination protection must be provided by the surrounding machine design. Standard dynamic balancing helps keep residual vibration low during high-speed operation.
