Product Description:

The MDD025B-N-100-N2G-040MD1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. It serves as the rotary element in drive trains controlled by digital amplifiers, converting commanded currents into accurate torque and speed for pick-and-place units, small indexing tables, or feeder rolls. Because a blocking brake is built in, the motor can keep a light load stationary when power to the drive controller is switched off.

Under continuous excitation at standstill, the rotor produces 0.60 Nm of torque, a value that lets the drive hold position during dwell periods without overheating. When velocity control is active, the unit reaches a nominal speed of 10000 rpm, matching fast cycle requirements in electronic assembly or light machining. Accurate mechanical centering is achieved with a 40 mm pilot diameter on the mounting face, ensuring coaxial alignment with adjoining equipment. Rotor position is tracked by resolver feedback, which tolerates electrical noise better than incremental encoders and provides position data for closed-loop control. Load coupling relies on a shaft with a keyway, so torque is transmitted without slippage.

Power and feedback conductors are routed on side B, and a connecting cable with a coupling unit simplifies installation without custom plugs. The internal brake develops 1.0 Nm of static torque to lock the axis, complementing the motor’s standard balancing and standard housing for smooth rotation. The motor has size 025 and length code B, allowing it to fit inside narrow mechanical envelopes, while the shaft is provided only on the drive side to save depth. The motor is delivered without a shaft seal, so external splash protection must be considered when it is mounted in fluid-rich work zones.
