MDD025B-N-100-N2G-040MC0
The MDD025B-N-100-N2G-040MC0 is a compact synchronous servomotor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into precise rotary motion for fast positioning stages and light spindle duties in automated assembly lines. Its small format suits equipment where installation space is limited, and its response supports repeatable motion during rapid start-stop cycles. That makes it suitable for compact indexing units, laboratory handlers, and other machines that benefit from quick response and stable speed control.
Its nominal speed of 10000 rpm permits direct coupling to high-speed mechanisms, while the motor can sustain a continuous stall torque of 0.60 Nm to hold loads during dwell periods. A 40 mm centering diameter aligns the stator face with the mounting pilot, which helps reduce radial misalignment at speed. Connections exit on Side A, keeping power and feedback conductors on one side of the machine frame. The motor uses a connecting cable with coupling unit, so it mates to the drive without additional terminal hardware. Torque is transmitted through a precision-ground keyway shaft, allowing rigid fixation of pulleys or collets and supporting reliable torque transfer during repeated acceleration.
The rotor uses standard balancing, which supports smooth running at high rotational speed. Motion feedback is provided by resolver feedback, giving analog sine-cosine signals for closed-loop current and velocity control. Because the motor uses resolver signals rather than a digital encoder, the feedback path remains simple and robust in electrically noisy environments. The motor is supplied without a blocking brake, so vertical or suspended loads must be secured by external holding methods when power is removed. The housing encloses the windings in a standard motor body, the shaft has no seal to minimize friction, and the output shaft is present only on the drive side.
