MDD025A-N-100-N2K-040ME1
The MDD025A-N-100-N2K-040ME1 is a high-speed synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for closed-loop positioning tasks on digital drive controllers, where commanded current is converted into precise rotary motion for pick-and-place heads, small gantries, and packaging axes. The compact housing supports installation close to the driven load, which helps reduce coupling length and maintain responsive motion in space-limited automation equipment. Its low mass also suits applications that need quick starts, frequent direction changes, and stable speed control during short production cycles.
At standstill, the rotor supplies a continuous torque of 0.33 Nm, which provides holding force for light indexing duty without overheating. The motor reaches a nominal speed of 10000 rpm, allowing direct coupling to small belt drives or gear stages where high shaft speed is useful. A blocking brake rated at 1.0 Nm adds holding support during emergency stops or when the axis must remain secured after power is removed. Position data come from an integrated absolute encoder, and Resolver feedback supports commutation and fine velocity control. A 40 mm centering diameter helps align the motor accurately on the mounting face, and the housing uses a connecting cable with a coupling unit for power and feedback connections. The motor is delivered without a shaft seal, so the front bearing area must be protected if liquids are present.
The motor has a size code of 025 and a length code of A, giving it a short body for installations with limited machine space. Cables exit on the left side, which helps keep routing predictable when the motor is mounted in narrow enclosures or beside neighboring components. The output uses a keyway shaft to transmit torque directly to pulleys or couplings, and the shaft arrangement is single-sided to keep the load end compact. As a motor intended for digital drive controllers, it is suited to motion systems that require coordinated control of position, speed, and torque across repeated cycles.
