MDD021A-N-100-N2G-032FB0
The MDD021A-N-100-N2G-032FB0 is a compact synchronous servo motor built by Bosch Rexroth Indramat and positioned within the MDD Synchronous Motors series. In digital drive systems, it functions as a rapid-response actuator that translates controller commands into precise rotary motion for lightweight tooling, pick-and-place axes, or indexing tables. Its small frame, low inertia, and electronic commutation suit tasks that demand high speed control, accurate positioning, and stable motion during frequent starts and stops in industrial automation. When paired with a compatible digital servo drive, it can support quick position corrections and short settling times on compact machine axes.
During continuous stall, the motor develops 0.15 Nm of torque, indicating the load it can hold indefinitely without overheating when locked in place. A nominal speed of 10000 rpm gives the motor a high rated operating velocity under standard cooling and supply conditions, enabling fast-cycling servo loops. Rotor feedback is provided through a resolver, so the drive receives rotor position data through an analog feedback device that remains resistant to electrical noise. Power and feedback conductors terminate through a connector, and all conductors exit on Side B to keep cabling clear of the driven shaft during motion.
The rotor uses standard balancing, which helps limit vibration at high speed and protect the bearings. A centering diameter of 32 mm supports accurate registration in precision mounting flanges and helps the motor seat consistently on mating surfaces. For applications that rely on external mechanics to hold position, the unit is supplied without a blocking brake, which removes residual drag from the motor assembly. The output uses a plain shaft with no secondary shaft end, making it suitable for compact couplings, miniature gearheads, or small belt pulleys where installation space is limited. This shaft arrangement also keeps the drive end simple for direct coupling components that do not require a keyed interface or additional sealing parts.
