MDD025B-N-100-N2K-040MD1
The MDD025B-N-100-N2K-040MD1 synchronous motor is manufactured by Bosch Rexroth Indramat and is part of the MDD Synchronous Motors series. Intended for digital drive controllers, it turns supplied current into controlled rotary motion for compact pick-and-place modules, indexing tables, and other high-speed automation axes. Its compact format suits installations where several motion components must fit into a limited machine envelope while still providing accurate positioning and repeatable speed control.
Its continuous stall capability of 0.60 Nm indicates the maximum static load the rotor can hold while energized, and the rated mechanical output reaches 10000 rpm for rapid cycle execution. A blocking brake inside the housing supplies 1.0 Nm of holding force to secure the shaft when power is off. Precise concentric mounting is aided by a centering diameter of 40 mm, while all power, signal, and brake leads exit on Side B through a connecting cable with a coupling unit. The rotor and housing use standard balancing, the enclosure is the standard version, and the shaft is a single-ended design because no side-B extension is fitted. A shaft seal is not included, so the motor is better suited to installations that avoid splashing liquids or fine abrasive dust.
The frame corresponds to Motor Size 025, giving the motor a small outer diameter that fits easily into multi-axis arrangements. Torque is delivered through a keyway shaft for positive mechanical engagement with gears or pulleys. Position data at power-up is provided by an integrated absolute encoder, and high-resolution speed feedback during motion is handled by the built-in resolver feedback system. Length code B indicates the internal lamination stack, balancing thermal capacity against overall motor mass. Standard housing construction without auxiliary cooling keeps weight low, and the lack of a shaft seal reduces friction for higher speed operation in precision spindles, small robotic wrists, and test fixtures.
