Product Description:

The MDD025C-N-100-N2G-040MC0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for pairing with digital drive controllers, it turns commanded stator currents into precise rotary motion for pick-and-place heads, miniature slides, and other high-speed automation axes. The motor occupies the 025 frame class and length code C, giving it a short housing for compact machine spaces without sacrificing dynamic response. Its synchronous design supports accurate speed and position control during repeated indexing and positioning tasks.

Its mechanical interface starts with a centering pilot of 40 mm, aligning the flange precisely and helping keep radial runout low. Power and feedback conductors exit on Side A, so the cable set can follow the moving axis and help avoid twisting. The motor includes a connecting cable with coupling unit, allowing quick disconnection when the assembly must be separated. Under continuous stall, it delivers 0.90 Nm of torque for holding static loads at standstill. At rated frequency, the rotor reaches 10000 rpm, giving ample speed reserve for short indexing moves. Standard dynamic balancing helps limit vibration during high-speed operation.

The motor is supplied without a blocking brake, so holding force must be provided by the drive or external mechanics when power is removed. Position information comes from resolver feedback, which tolerates high acceleration while supplying continuous analog feedback to the controller. A keyway machined into the output shaft simplifies torque transmission, and the rotor is enclosed by a standard housing that matches common mounting footprints in the series. The shaft is present only on the drive end, and because there is no shaft seal, installation in a clean, dry compartment is recommended. The absence of a second shaft end leaves additional space behind the motor body for couplings, proximity switches, or cable management hardware.
