MDD025A-N-100-N2K-040GD0
The MDD025A-N-100-N2K-040GD0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts command signals into rotary motion that supports precise positioning and speed regulation on compact axes in assembly equipment, electronics pick-and-place stations, and small conveyor modules. Its compact format suits machinery where limited mounting space and responsive motion are both important. Electrical and feedback lines exit on Side B, so the installation should leave clearance at the non-drive end for cable routing.
The motor uses a size 025 housing with A-length construction, standard balancing, a plain shaft, and a standard shaft end on the drive side. The balancing arrangement supports smooth rotation at higher shaft speeds, and the plain shaft is suited for coupling arrangements that do not require a keyed output. At standstill, it can deliver 0.33 Nm of continuous torque, and the winding is designed to maintain that output within its thermal range. The rated operating speed reaches 10,000 rpm, which supports fast cycle times when the motor is paired with a suitable inverter. Power is supplied through a connecting cable with coupling unit, which helps keep wiring compact in tight machinery frames. The standard aluminum housing helps limit overall mass on small moving axes.
The feedback channel uses resolver feedback, which tolerates vibration and supplies sinusoidal position data to the drive controller. The motor is supplied without a blocking brake, so any holding force at standstill must come from an external device or the drive system. A centering flange diameter of 40 mm helps align the motor accurately with a gearbox or direct coupling. The motor also has a shaft seal, which helps keep lubricants inside the transmission and contaminants out of the bearing cavity.
