Product Description:

The MDD025A-N-100-N2G-040GL0 is a compact AC servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts regulated current from an inverter into precise rotary motion for positioning tables, pick-and-place heads, and other high-speed axes found in automated assembly cells. The model uses a plain shaft, a standard housing, and a connector-based power and feedback interface that simplify wiring in tight machine frames. Its compact format also suits applications where moving mass and installation space must be kept to a minimum.

Performance figures show how the motor behaves under load. Its nominal speed is rated at 10000 rpm, allowing rapid cycle times when paired with a suitable drive. At standstill, it can hold a continuous torque of 0.33 Nm, which helps protect the position loop from drift during dwell periods. Mounting alignment is simplified by a centering pilot of 40 mm that matches standard servo flanges. All electrical terminations exit on the left side, a layout that keeps the cable bundle clear of adjacent axes in multi-motor gantries. Rotor position is returned to the controller through resolver feedback, providing analog angle detection that remains accurate across a wide temperature range and at high rotational speeds.

The motor is supplied without a blocking brake, so external holding devices or drive torque must secure vertical loads when power is removed. A sealed front bearing system identified as with a shaft seal blocks coolant spray and fine dust from entering the stator cavity. Its frame size code of 025 keeps mass and inertia low for light pick-and-place tools, while standard balancing helps limit residual vibration during direct coupling to precision gearheads. The unit also has a connector interface, motor length code A construction, and a standard shaft end on side A only. It uses a plain shaft type to accommodate industry-common clamping hubs in compact machine layouts.
