MDD025A-N-100-N2K-040FC0
The MDD025A-N-100-N2K-040FC0 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers and converts electrical energy into high-speed rotary motion for pick-and-place heads, miniature spindles, and indexing tables in automated production lines. Its compact housing helps the motor fit close to the driven mechanism, which is useful where installation space is limited. The mounting geometry also supports direct integration into small axis assemblies that need fast response and consistent positioning.
The motor reaches a nominal speed of 10,000 rpm, allowing very high rotor speed under rated operating conditions. At standstill, it can deliver 0.33 Nm of continuous torque, which is suitable for light loads that still require stable holding force during active control. Precise alignment is supported by a centering diameter of 40 mm, and power and signal lines enter from side A through a connecting cable with coupling unit, which helps keep cable routing compact. Position data is supplied by an integrated absolute encoder, so the drive can recognize rotor position immediately after power-up and maintain controlled motion without a homing cycle.
The 025 frame keeps moving mass low, which helps the motor respond quickly on short-stroke axes and other compact motion systems. Its standard balancing supports smooth rotation and helps reduce vibration at high speed. The motor uses a plain shaft for direct coupling to suitable transmission components, and it is supplied without a blocking brake, so any power-off holding function must be provided externally. Encoder-based feedback supports commutation and speed control across the operating range, which helps maintain stable motion in applications that require rapid starts, stops, and repeatable positioning.
