MDD025C-N-100-N2G-040FL0
The MDD025C-N-100-N2G-040FL0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it provides precise rotary positioning and velocity control in automated production lines, pick-and-place stations, and similar motion platforms. It is intended for servo systems that need stable speed control and repeatable positioning during short, frequent motion cycles. Its compact size suits axes where low moving mass and fast response are important. The motor is supplied without a blocking brake, which reduces inertia for rapid acceleration profiles.
This unit delivers a continuous standstill torque of 0.90 Nm, allowing a drive to hold a load at zero speed without additional gearing in light-duty applications. Its rotor can reach a nominal speed of 10000 rpm, which suits high-throughput axes where rapid indexing is required. The motor has a 025 frame size and C length, which keep mass low while leaving room for heat dissipation. Power and feedback conductors exit on the left side through a sealed circular connector, which can simplify cable routing inside compact machine frames. A standard aluminum housing and a connector interface built for industrial use support installation in enclosed automation equipment.
Dynamic balance is graded as standard, so coupling vibration remains within normal limits at full speed. Precise mounting is aided by a 40 mm centering diameter that aligns the flange with gearbox or bracket bores. Position data is returned through resolver feedback, which supplies sinusoidal signals that many legacy and current drive controllers can decode. This feedback method is commonly used where robust analog position signals are preferred over digital encoder channels. The motor has a plain shaft that mates directly with compression couplings, so there is no keyway or secondary shaft end. Because the shaft seal is omitted, the application must protect the shaft area from coolant or oil ingress, and the shaft end remains on the standard A-side only.
