MDD025B-N-100-N2K-040ML1
Bosch Rexroth Indramat builds the MDD025B-N-100-N2K-040ML1, a member of the MDD Synchronous Motors series. This motor for digital drive controllers delivers commanded torque to compact positioning stages, indexing tables, and light-duty spindles found in automated assembly lines. By integrating directly with inverter outputs, it transforms electrical setpoints into repeatable rotary motion, allowing precise placement and velocity control where limited footprint and rapid cycle times are required. Its compact format also suits installations where motor mass and mounting space must stay low without reducing closed-loop response. This makes it suitable for small axes that must start and stop quickly while maintaining stable speed control.
It produces a continuous torque of 0.60 Nm at standstill, so the axis can hold a load while the motor remains energized. A nominal speed of 10000 rpm supports fast indexing tasks, and the integrated blocking brake provides 1.0 Nm of static holding torque when power is removed. Mechanical alignment uses a 40 mm centering diameter, which helps the housing seat accurately in flange adapters and reduce radial runout. The motor uses frame size 025 for compact automation heads, and standard dynamic balancing helps reduce vibration during operation.
Position feedback is supplied by an integrated absolute encoder together with resolver feedback, giving the drive controller startup position information and stable motion feedback during operation. The compact motor length code B helps keep inertia low, and torque is transmitted through a keyway shaft for use with keyed couplings or pulleys. The design is supplied without a shaft seal, so the installation should keep fluids away from the shaft journal. A standard shaft end on side A and no shaft extension on side B simplify coupling alignment, while the left-side connector keeps cable routing on one side of the motor.
