Product Description:

Bosch Rexroth Indramat produces the MDD025A-N-100-N2G-040PD1 synchronous motor for digital drive controllers, placing it within the MDD Synchronous Motors series. This compact unit converts drive-generated current into rotational motion for light-duty axes in industrial automation. Its small footprint makes it suitable for compact positioning, handling, and indexing equipment where fast response and precise control are required.

The motor supplies a continuous standstill torque of 0.33 Nm, allowing closed-loop drives to maintain position under light static loads without overheating. At its rated speed of 10000 rpm, it can follow high-velocity command profiles used in pick-and-place tooling for semiconductor and assembly lines. Position information is returned to the controller through resolver feedback, giving analog angular data that supports sinusoidal commutation and stable control across the speed range. Power, feedback, and brake leads exit at the rear and are preassembled as a connecting cable with coupling unit, which reduces separate connection points. Accurate centering against gearboxes or bearing plates is assisted by a 40 mm centering diameter, which aligns the stator housing with mating flanges.

The rotor includes a 1.0 Nm holding brake that locks the shaft during power-off events and prevents back-driving on vertical axes. Mechanical power is transmitted through a keyway shaft profile, and sealing is provided by a shaft seal that limits dust and lubricant entry into the bearing area. All service connections remain on Side B, which keeps cabling on one end of the housing. The motor uses frame size 025 with length code A, giving it a short body for compact machines, and the standard balancing grade supports smooth running over the full speed range. The shaft end is supplied without a secondary output shaft, which reduces coupler mass.
