MDD021A-N-100-N2G-032MA0
The MDD021A-N-100-N2G-032MA0 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies responsive rotary motion for pick-and-place heads, labeling stations, and other light industrial axes that demand fast acceleration. The rotor’s permanent-magnet design matches the high switching frequencies of Indramat drives, allowing accurate torque production while keeping the package small enough for tight mounting envelopes on machinery frames. Its compact format suits machine layouts where the motor must fit close to tooling, guards, or transfer mechanisms.
Its centering pilot is 32 mm, giving a reference surface for flange alignment and repeatable shaft concentricity. At standstill, the motor can deliver 0.15 Nm continuously without exceeding thermal limits. A rated speed of 10000 rpm permits direct coupling to small spindles. Power and feedback are routed through a single connector, and rotor position is detected by resolver feedback so the controller can close synchronous control loops during reversals. The cylindrical output end has a keyway, which transmits torque to pulleys or couplings without relying on friction fits.
The rotor is trimmed with standard balancing to keep vibration within ISO limits. The electrical plugs face Side A, simplifying cable runs along the drive side of a machine. The frame uses standard housing proportions and is supplied without a shaft seal, so the front bearing must be protected if liquid ingress is expected. Because the motor is supplied without a blocking brake, external braking or drive-torque holding is required during power-off conditions. Size designation 021 and length code A indicate a short stator stack that reduces mass, and the shaft is machined only on the drive side with no side-B extension. The single-sided shaft arrangement leaves the rear of the motor clear for mounting in closely spaced assemblies.
