Product Description:

The MDD025A-N-100-N2G-040GR1 is a compact servo motor from Bosch Rexroth Indramat that belongs to the MDD Synchronous Motors series. Intended for use with digital drive controllers, it converts regulated inverter current into precisely controlled rotary motion for lightweight positioning axes in automated assembly, test, and electronics handling equipment. The design supports closed-loop speed and torque regulation so rapid setpoint changes can be executed without overshoot or oscillation. This makes the motor useful for small axes that require repeatable motion and quick directional changes in limited installation space.

The rotor is engineered for a nominal speed of 10,000 rpm, enabling short machine cycle times when driven by high-frequency inverters. At standstill, it delivers a continuous torque of 0.33 Nm, allowing small loads to be held without excessive heat buildup. An integrated blocking brake supplies up to 1.0 Nm, keeping the shaft locked during power-off or emergency-stop events. Power and feedback lines terminate on a keyed connector on the right side, which simplifies cable routing in compact cabinets. Position and velocity data are returned through resolver feedback, which tolerates electrical noise and high rotational speeds.

Mechanical integration is based on a centering diameter of 40 mm, which provides a repeatable pilot surface for flange mounting. The drive end features a plain shaft without a secondary output, reducing mass and easing coupler alignment. A fitted shaft seal helps prevent lubricant migration and protects the front bearing from fine particulates. Rotor mass distribution follows standard balancing, which helps maintain smooth running across the operating range. The housing relies on natural convection, and the short A length keeps the motor compact for gantry or pick-and-place systems where available space and moving mass are limited.
