MDD025A-N-100-N2K-040PB0
The MDD025A-N-100-N2K-040PB0 is a small synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts commanded electrical input into precise mechanical rotation for light-duty axes in packaging machines, electronics assembly systems, and other compact automation equipment. The motor is suited to applications that need quick response, repeatable positioning, smooth low-speed control, and short travel distances. It is also suitable for small handling modules and inspection stations where acceleration must remain controlled and consistent from cycle to cycle.
Its rated mechanical data includes a nominal speed of 10000 rpm, which supports very high surface velocity when the motor is paired with fine-pitch screws or belt-driven mechanisms. At standstill, the motor can provide a continuous torque of 0.33 Nm, allowing it to resist light static loads without exceeding thermal limits during normal operation. Mounting alignment is supported by a 40 mm centering pilot, which helps seat the motor accurately against the machine face. Power and feedback connections leave the housing on side B through a single connector, which keeps the drive end clear and simplifies cable routing in crowded machine spaces. This layout can be useful when the driven side faces a gearbox or pulley.
The rotor uses standard balancing to keep vibration within normal limits during high-speed operation and to support smoother running in compact axes. Position data are supplied by an integrated absolute encoder, allowing the drive to maintain closed-loop control and recognize rotor position immediately after startup. The motor is supplied without a blocking brake, so any load that must remain fixed after power removal requires external holding force or drive-generated torque. Torque is transmitted through a keyway shaft end, while the opposite end remains plain to save space around the installation and simplify coupling to small motion components. This arrangement is common on compact servo assemblies that prioritize direct coupling and low installation depth.
