Product Description:
The MDD021A-N-100-N2K-032MA0 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. As a small-frame synchronous servo motor, it interfaces with digital drive controllers to deliver finely modulated rotary motion in compact automation axes such as pick-and-place heads or miniature positioning stages. Its construction follows the series’ standard housing rules, and it is supplied with a single shaft end intended for tight mechanical envelopes where only one coupling surface is required.
The motor develops a continuous standstill torque of 0.15 Nm, allowing stable holding or low-speed duty without exceeding thermal limits. Under rated excitation it can reach a nominal speed of 10000 min⁻¹, a value that suits high-throughput machinery needing rapid acceleration and deceleration. Accurate concentric mounting is supported by a centering diameter of 32 mm, which fits directly into precision flanges to minimize radial run-out. All power and sensor leads exit on Side A, simplifying cable management when the drive is mounted against fixed panels. The power interface is a sealed Connector, so field wiring can be disconnected without opening the motor enclosure or disturbing alignment.
Position data is generated by integrated resolver feedback, enabling sinusoidal commutation and electronic nameplate functions over a single feedback channel. The unit is built without a blocking brake, so any holding force must be provided by the drive or external mechanics. Mechanical coupling is through a keyed shaft specified as a keyway, giving positive torque transmission in both rotational directions. The frame code 021 indicates the smallest stator diameter in the MDD family, while length code A keeps mass and inertia low. Standard balancing, absence of a shaft seal, and a single-sided shaft end further streamline installation where ambient conditions are clean and space is restricted.
