Product Description:

The MDD025A-N-100-N2K-040PE0 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for use with digital drive controllers, it converts precisely modulated current into mechanical rotation for pick-and-place arms, indexing tables, and other high-speed automation axes. The frame, balancing, and housing follow the standard mechanical outline of the series, so the motor can fit existing brackets and protective enclosures without changes to the mounting arrangement. Its compact format also suits densely packed equipment where low moving mass and short cycle times are important.

Its continuous stall torque is 0.33 Nm, which is the load the shaft can hold continuously without exceeding thermal limits. During operation, the rotor reaches a nominal speed of 10000 rpm, supporting direct coupling to miniature gearheads that rely on high input speed. Accurate alignment to driven components is supported by the 40 mm centering diameter, which keeps the motor concentric to the machine frame. Cabling exits on the left side, and power plus feedback conductors are routed through a connecting cable with a coupling unit to support orderly cable routing and shield continuity. The cable exit position can also help in compact housings where rear clearance is limited.

Position data comes from an integrated absolute encoder, while velocity loops are derived from the motor's resolver feedback for precise dynamic control. The unit is supplied without a blocking brake, so holding torque must be provided by the controller or external mechanics when power is removed. A shaft seal protects internal bearings, and the single-ended keyway shaft simplifies coupling to pulleys or keyed hubs. With a frame size code of 025 and length code A, overall inertia and mass stay low for compact axes that demand quick acceleration and modest payload handling. This layout is suitable for small motion systems where installation space is limited and rapid directional changes are common.
