Product Description:

The MDD025C-N-100-N2G-040FB1 is a servo motor developed by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to interface directly with digital drive controllers, the unit converts electrical power into fast rotary motion for compact pick-and-place heads, indexing tables, and light-duty spindles in automated lines. A single front-mounted connector accelerates installation, and the standard cast-aluminum housing maintains enclosure integrity without auxiliary fans.

Performance ratings define the operating window of the drive. The motor achieves a nominal speed of 10000 min⁻¹, permitting high cycle frequencies without gear reduction. At standstill it produces 0.90 Nm of continuous torque so small loads can be held in position under closed-loop regulation. For power-off retention, the integrated blocking brake delivers 1.0 Nm of torque. A 40 mm centering diameter aligns the flange to precision fixtures, and the rotor is balanced to the standard grade to limit vibration. Power and feedback conductors exit on Side B of the frame, keeping service loops clear of the shaft. All terminations use a circular connector, and the housing follows a passive, surface-cooled design.

Dimensional coding finalizes the mechanical envelope: size 025 fixes the stator outer diameter, while length code C establishes the active stack length that supports the stated torque. Position data are supplied through resolver feedback, giving analog sine-cosine signals that remain accurate across the full speed range. The unit is delivered without a shaft seal, so external protection is required when contaminants are present. A plain shaft, the omission of the side-B shaft end, and the absence of a keyway simplify coupling to miniature belt pulleys or collets while minimizing overhang mass.
