Product Description:

The MDD025A-N-100-N2K-040GB1 is a miniature synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts drive current into precise rotary motion for pick-and-place axes, compact positioning stages, and other high-speed automation tasks. Its compact format also suits machines where limited installation space and repeatable motion are both important.

Balancing is standard, so rotor mass distribution meets ISO quality grades without additional field trimming. At standstill, the motor can deliver 0.33 Nm of continuous torque for holding or low-speed motion before thermal limits are reached. When energized at rated voltage, it reaches 10,000 rpm, allowing fast cycle times in light servo axes. Power and feedback cables exit on side B, and a keyed connector simplifies plug-in installation. A centering diameter of 40 mm supports accurate flange alignment to a gearbox or bracket. Position data is supplied by an integrated absolute encoder, so no external sensor mount is needed. The housing and shaft end follow the standard versions in the series, and the short motor length helps the unit fit dense multi-axis assemblies.

A blocking brake is included and produces 1.0 Nm of torque to hold the shaft when power is removed, which helps prevent drift on vertical axes. Feedback to the controller can also be obtained through resolver feedback, allowing compatibility with drives that use analog position transducers. The motor is built with a shaft seal, which helps protect the internal bearings from coolant splash or dust. Its plain shaft geometry helps minimize coupling runout. Because the shaft end is supplied without a second side-B extension, the motor can mount flush against adjacent components while keeping the rear connection area accessible.
