Product Description:

The MDD025C-N-100-N2G-040GD1 is a synchronous AC servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it converts commanded current into tightly regulated rotary motion for automated pick-and-place heads, miniature conveyors, and other high-speed stations. The size 025 frame and compact length let machine builders insert the unit into narrow mechanical envelopes while still achieving the dynamic response needed for precise industrial positioning tasks.

The motor delivers a continuous standstill torque of 0.90 Nm, so light loads can be held without external gearing. Its rotor reaches a nominal speed of 10000 min⁻¹, giving short cycle times in spindle-style applications. A 40 mm centering diameter aids alignment, and the rotor meets standard balancing to limit vibration. Power and feedback leads exit on Side B, streamlining cable runs in rear-mounted installations. The housing follows the standard enclosure outline, a shaft seal blocks coolant ingress, and the single front shaft end removes extra overhung load points. Length code C defines the lamination stack used to obtain the stated torque without enlarging the motor body.

For electrical hookup, the unit employs a connecting cable with coupling unit, so the connector locks without tools. An internal blocking brake applies 1.0 Nm of holding torque when the drive is de-energized, keeping vertical or inclined axes stationary. Closed-loop regulation is performed with resolver feedback, which provides absolute rotor position data for the controller. The rotor uses a plain shaft, allowing press-fit pulleys or precision couplings without keyways. With its standard housing, shaft seal, and the size 025 / length C geometry, the motor integrates easily into compact automation modules that rely on Bosch Rexroth digital drives.
