MDD025C-N-100-N2G-040PC0
The MDD025C-N-100-N2G-040PC0 is a compact AC servo unit produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into controlled rotary motion for accurate position and velocity control. In this type of servo system, the drive regulates current continuously so the axis can accelerate, decelerate, and settle with low error during repeated motion cycles. That operating role suits machine tools, pick-and-place axes, and packaging equipment where a compact motor must deliver repeatable movement without excessive lag.
A centering shoulder of 40 mm fits precision bores for accurate mounting, and the rotor can reach a nominal speed of 10000 rpm. The motor provides a continuous standstill torque of 0.90 Nm, which supports static load holding when the drive is energized. Power and feedback conductors exit on Side A, and the unit uses a connecting cable with coupling unit for a direct wiring arrangement. Standard dynamic balancing helps reduce vibration during high-speed operation, which is useful in compact machine layouts with limited clearance around adjacent components.
Motion feedback is provided by resolver feedback, which gives the drive the rotor position needed for closed-loop control. The output shaft uses a keyway for torque transmission, and a shaft seal helps protect the front bearing area from coolant spray. The motor is supplied without a blocking brake, so load holding at standstill must be provided by the drive or by an external clamp. Its single-ended shaft, standard housing, motor size 025, and length code C keep the package compact for installations where space is limited and consistent servo response is required.
