Product Description:

The MDD025A-N-100-N2G-040FC0 is a compact synchronous motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into controlled rotary motion for high-speed positioning stages, pick-and-place axes, and other automated machinery within industrial cells. Its compact format supports installation in equipment that has limited space around moving components. The motor is suited to applications that rely on quick response and repeatable speed tracking during frequent start-stop cycles.

At a nominal speed of 10,000 rpm, the rotor can support rapid motion cycles, while a continuous standstill torque of 0.33 Nm supports light holding duty at zero speed. The flange uses a 40 mm centering pilot for accurate alignment to adjacent machine parts. The rotor and mounting surfaces use a standard balancing grade, and the A-length housing keeps the body short to help limit moving mass. Power conductors leave on Side A, which can simplify routing where cables must stay clear of nearby mechanisms. Motion feedback is supplied through resolver feedback, allowing the drive to monitor rotor position and regulate the servo loop during acceleration and speed changes.

Power and signal cabling is provided through a connecting cable with a coupling unit that locks to the motor connector without additional hardware. The motor is supplied without a blocking brake, so any holding function must come from the drive or external mechanics when the axis is stopped. It is also supplied without a shaft seal, which makes it better suited to clean, dry installations or to assemblies in which sealing is handled elsewhere. The plain shaft has no side-B extension and is intended for friction or collet couplings rather than keyed hubs. With frame size 025, the motor fits compact axis layouts where low inertia and high reference speed are important.
