Product Description:

The MDD025A-N-100-N2K-040GE1 is a synchronous servo motor in the MDD Synchronous Motors series from Bosch Rexroth Indramat. Designed for use with digital drive controllers, it supports positioning and velocity loops in automated machinery where a compact footprint and high speed are important. This type of motor is commonly used on small handling axes, compact indexing units, and other machines that need accurate closed-loop motion. The shaft transfers torque directly to couplings or pulleys. A built-in blocking brake holds the load when power is removed, which makes the unit suitable for axes that must remain at rest between moves.

At standstill, the motor can deliver a continuous torque of 0.33 Nm. Its rated mechanical speed reaches 10000 rpm, so it suits applications that require very fast rotation in a small frame. The combination of low continuous torque and high speed fits light-duty axes that favor quick response over heavy load capacity. A centering pilot of 40 mm helps align the motor accurately with a gearbox or machine plate. For holding at rest, the blocking brake provides 1.0 Nm of holding torque. The rotor is balanced to the standard grade to help keep vibration low during high-speed operation.

Electrical and feedback connections exit on the left side, and power is routed through a connecting cable with a coupling unit, which reduces enclosure depth because no fixed plug protrudes. Motion feedback to the drive is carried by resolver feedback, which remains reliable across electrical noise and temperature changes. The output uses a plain shaft with a shaft seal to limit lubricant migration and particle ingress. The housing uses the standard cooling method for the series, while the size-025 frame with length code A helps keep inertia low for light tooling. Because there is no side-B shaft, adjacent axes have more clearance and the installation depth stays compact.
