Product Description:
The MDD021A-N-100-N2G-032FB0 is a synchronous servo motor built by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded currents into precise rotary motion for positioning or velocity loops in compact automation axes. Its small 021 frame and A length code make it suited for light tooling, pick-and-place heads, and semiconductor stages where high speed and limited continuous torque are acceptable in industrial automation. This makes it suitable for benchtop automation modules and tightly spaced assemblies where a larger motor would add unnecessary moving mass.
The centering diameter of 32 mm is the mounting register that aligns the stator within a machine frame. Power and feedback conductors exit on side B, and the single-piece connector simplifies plug-in installation without terminal blocks. Under continuous stall conditions, the motor supplies 0.15 Nm, which is the maximum static torque available before motion begins. When commutated by the drive, the rotor reaches 10000 rpm, allowing short positioning times in systems that tolerate low inertia. Standard dynamic balancing keeps vibration within ISO grades appropriate for these speeds, and the housing remains convection cooled.
The servo transmits position through resolver feedback, giving analog sine-cosine signals that the controller converts to high-resolution angle data over the full speed range. A plain shaft couples directly to miniature pulleys or gearheads, and it is supplied without a shaft seal, so the installation area must stay free of pressurized liquids. The absence of a shaft seal makes the motor better suited to clean, dry environments than to coolant-heavy areas. The motor is delivered without a blocking brake, so holding torque must be provided externally when power is removed. The standard housing shares dimensional patterns with other MDD units, while motor size 021 and length code A keep mass low for applications that benefit from rapid acceleration.
