Product Description:

The MDD025C-N-100-N2G-040MD0 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat as a member of the MDD Synchronous Motors series. Intended for integration with digital drive controllers, it supplies precise rotary motion to axes that demand rapid acceleration and repeatable speed profiles in assembly cells, semiconductor handlers, and other automated equipment. Its electrical design produces torque directly on the shaft, minimizing backlash and reducing maintenance in multi-axis modules. This layout is well suited to compact positioning axes where stable speed control and fast direction changes are required.

The mechanical interface uses a centering collar of 40 mm, allowing the housing to locate firmly in precision mounting fixtures. At zero speed, the stator can deliver 0.90 Nm of continuous holding torque, enabling light load retention without external brakes. For dynamic tasks, the rotor is rated to reach 10,000 rpm, so small indexing movements can be executed within milliseconds. Service leads exit on side B, a layout that keeps connectors away from the driven shaft and simplifies cable routing in dense machines. Closed-loop regulation is performed through resolver feedback, providing rotor position data during rapid reversals and maintaining commutation integrity across the full speed range.

The motor has size 025 with code C body length, placing its mass and inertia in a range suited for small manipulators and spindle drives. Power and feedback are routed through a connecting cable with coupling unit, which preserves shield continuity and supports quick cable replacement when access space is limited. Standard balancing limits residual vibration at high shaft speeds, even though the assembly is delivered without a blocking brake or a shaft seal. The output uses a hardened keyway, making it compatible with set-screw pulleys or pinion gears used on miniature belt or rack transmissions.
