Product Description:

The MDD025B-N-100-N2K-040FC1 is a compact synchronous motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for direct coupling to digital drive controllers, it delivers high-precision rotary motion to light-duty axes such as pick-and-place heads, small indexing tables, and electronic cam followers. Its low-inertia design supports rapid acceleration while maintaining accurate position control in automated assembly, packaging, and handling equipment. This layout suits compact servo axes where low moving mass and fast response are needed for short, repeatable cycles.

The motor uses frame size 025 and the B-length stator to keep overall dimensions low while still providing a continuous standstill torque of 0.60 Nm. The longer stator stack improves thermal capacity without changing the footprint, and standard dynamic balancing helps reduce residual vibration during high-speed operation. A centering shoulder of 40 mm ensures repeatable alignment against mounting flanges, and the rotor can reach 10,000 rpm. Power and feedback conductors exit on the A-side, and a connecting cable with coupling unit supports quick, keyed attachment in confined electrical cabinets. Keeping both connections on one end can simplify cable routing in tightly packed machine sections.

A blocking brake supplies 1.0 Nm of holding torque to secure the rotor when the drive is de-energized, and it releases automatically when excitation current is restored. Because the unit is supplied without a shaft seal, it is intended for clean, dry enclosures where sealing is handled by the machine frame. That arrangement is better suited to protected installations than to areas with coolant splash or airborne debris. Position data are delivered through resolver feedback for closed-loop control. The motor uses a single plain shaft without a side-B extension.
