Product Description:

The MDD025A-N-100-N2G-040PB1 is a compact synchronous motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Built for digital drive controllers, the unit converts commanded current into precise high-speed rotation for automated positioning axes and auxiliary drives. Its standard housing, A-length frame, and single shaft end give machine builders a space-saving solution for continuous industrial duty. The compact format also suits small motion assemblies where installation space is limited but accurate servo response is still required.

At its rated point, the motor reaches 10,000 rpm under rated electrical conditions. Continuous stall torque is 0.33 Nm, which is the sustained twisting force available without overheating when the rotor is held stationary. Accurate mounting is aided by a 40 mm centering diameter. All power and feedback leads exit on side B, which helps keep cable routing close to the drive face in compact layouts. The windings connect through a plug-in connector, which provides a secure electrical connection in applications where vibration is present.

An integrated blocking brake supplies 1.0 Nm of static torque, holding the shaft during power loss or emergency stops on vertical axes. Rotor position is returned to the controller through resolver feedback, which tolerates electrical noise and high acceleration while supplying angle data for closed-loop control. Torque is transmitted through a shaft with a keyway, and a fitted shaft seal helps keep lubricant in and contaminants out during washdown or coolant exposure. Balanced to the series standard grade, the motor runs smoothly throughout its speed range. This layout is well suited for compact spindles, pick-and-place heads, and indexing tables that require fast motion with dependable shaft holding during stopped conditions.
