Product Description:

The MDD025B-N-100-N2K-040MF0 is a small-frame synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for use with digital drive controllers, the unit converts controlled current into precisely regulated shaft rotation in automated assembly lines, electronic component handlers, and light material-processing stations. Its compact 025 frame and B-length housing support dense axis layouts, and the standard flange pattern suits equipment built around this motor size. This motor type is well suited to compact axes that require responsive motion and accurate speed control in limited installation space.

The motor sustains a nominal speed of 10000 rpm, enabling rapid indexing or spindle duty when commanded by the controller. A continuous standstill torque of 0.60 Nm is available while the motor remains within its thermal limits. Positional alignment to the machine frame is handled by a 40 mm centering pilot that helps limit radial runout. Wiring is simplified because all connectors face the right side, and the unit uses a connecting cable with a coupling unit that mates directly with the drive line. That layout helps keep cable routing clear in tightly packed machine sections and reduces interference with nearby mechanisms.

Standard balancing helps minimize residual vibration at the shaft flange during high-speed operation. Position data are issued by an integrated absolute encoder, while coarse commutation is supported through resolver feedback for startup alignment and closed-loop control. This feedback arrangement allows the drive to monitor rotor position continuously during acceleration, stopping, and reversal. Because the motor is supplied without a blocking brake, holding force must be provided by the drive or an external clamp on vertical axes. The output shaft uses a keyway and is shipped without a shaft seal, so the front bearing should be protected where liquids or fine dust are present.
