MDD025C-N-100-N2K-040MR0
The Bosch Rexroth Indramat MDD025C-N-100-N2K-040MR0 is a compact synchronous servo motor from the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into controlled rotary motion for small positioning axes in automated equipment. The motor suits applications that need quick response, accurate positioning, and a compact installation envelope. It is also appropriate for systems where short travel moves and repeated starts and stops are handled directly through closed-loop servo control.
When the axis is energized and stationary, the motor can deliver 0.90 Nm of continuous torque. During motion, it can reach a regulated speed of 10000 rpm, which supports rapid indexing and high-speed spindle tasks. Position information is supplied by an integrated absolute encoder, so the controller receives position data immediately after power-up. Velocity feedback is provided through resolver feedback, which offers sinusoidal signals that remain stable at elevated speeds and temperatures. The rotor uses standard balancing to help reduce vibration when it is coupled to light loads, and this supports smoother running during fast axis movement.
A centering diameter of 40 mm aligns the flange during mounting, and power plus feedback lines exit through a single connector on the right side for straightforward cable routing. The motor is supplied without a holding brake, so any load-holding function must be provided by the drive or by external mechanical hardware. Its output shaft uses a keyway profile for standard couplings, and the shaft is not fitted with a seal. The standard housing, C length code, 025 frame size, and single-ended shaft on side A keep the package compact for closely spaced axes and installations with limited clearance around the motor body.
