Product Description:

The MDD025A-N-100-N2G-040GR0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat in the MDD Synchronous Motors series. Built for use with digital drive controllers, it converts precisely metered three-phase current into regulated rotary motion for compact pick-and-place axes, labelers, and light machine spindles. High base speed and a small frame support short settling times in applications that require frequent starts, stops, and rapid direction changes. The standardized mechanical interface helps the motor fit established machine layouts without major hardware changes.

During rated operation, the rotor reaches 10000 rpm, allowing direct connection to small pulleys or timing belts without intermediate gearing. A continuous stall torque of 0.33 Nm provides the holding force available when commanded motion is zero. Precise positioning is helped by the 40 mm centering shoulder that aligns the flange concentrically to gearboxes or fixtures. Cables exit on the right side, and a single connector carries both power and resolver lines to simplify routing at the motor housing. The plain drive-side shaft reduces windage and inertia, and the absence of a shaft on side B keeps the package short for narrow machine frames.

Rotor dynamics are controlled by standard balancing, which helps keep vibration low across the speed range and supports stable motion. The housing uses the standard profile for this product line, and axial length code A indicates the shortest build in the size-025 platform. Because the motor runs without a blocking brake, any required parking torque must come from the drive or an external clamp. Position and speed data are delivered through resolver feedback, which remains reliable in electrically noisy machine environments. The motor size 025 frame has a front shaft seal that helps limit lubricant loss and protect the bearing set from spray.
