MDD025B-N-100-N2K-040ME0
The MDD025B-N-100-N2K-040ME0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts regulated current into precise rotary motion for assembly robots, compact conveyors, and light machining spindles. Its integrated feedback device streams position data directly to the controller, so speed and torque can be regulated in a closed loop even at high cycle rates. The small frame allows the unit to be installed close to the load, which can reduce coupling backlash and improve system stiffness.
Its continuous torque at standstill is 0.60 Nm, so it can hold a steady load at zero speed within its thermal limits. During operation, the shaft reaches a nominal speed of 10,000 rpm, which suits rapid indexing and high-speed positioning tasks. Accurate mechanical alignment is supported by a 40 mm centering diameter that seats the flange concentrically on the machine plate. Power and feedback conductors exit on the left side, which can simplify routing when several axes are mounted next to each other. Electrical termination uses a connecting cable with a coupling unit, allowing the motor to be disconnected without opening gland fittings. Commutation and velocity data are supplied through resolver feedback, which provides analog sine-cosine signals with good resistance to electrical noise.
Standard dynamic balancing helps keep vibration low across the speed range, and the housing uses the series' standard aluminum profile for efficient heat transfer. Because the motor is supplied without a shaft seal, it should be installed away from pressurized coolant or abrasive dust. The single output shaft has a keyway for positive torque transmission to gears or pulleys. A frame size of 025 keeps mass and inertia low, and static position holding must be provided by the drive because no holding brake is included.
