Product Description:

The MDD025A-N-100-N2K-040GC0 is a compact synchronous motor from Bosch Rexroth Indramat that belongs to the MDD Synchronous Motors series. Intended for use with digital drive controllers, it converts commanded electrical power into high-speed rotary motion for pick-and-place heads, small indexing tables, and other precision axes in automated equipment. Its mechanical envelope and electrical connections allow direct coupling to compatible servo drives so that speed and position are regulated in closed-loop control during repeated indexing and rapid direction changes. This arrangement supports precise speed control and repeatable positioning in compact automation cells where installation space is limited.

At standstill, the motor can deliver 0.33 Nm of continuous torque, enough to hold light loads while running within its thermal limits. It reaches a rated speed of 10,000 rpm, supporting short cycle times in equipment that needs rapid positioning. Mounting is simplified by the centering shoulder measuring 40 mm in diameter; this aligns the stator to adjoining frames and minimizes runout. Motion feedback comes from an integrated absolute encoder, so the controller knows the rotor angle immediately after power-up without a homing routine. The motor is delivered with standard dynamic balancing to limit vibration during continuous operation.

The electrical and mechanical interfaces are arranged on Side A, and power is routed through a connecting cable with coupling unit for a direct machine connection. The motor is shipped without a blocking brake, so external holding mechanisms are required if the axis must remain fixed when de-energized. A plain shaft with a shaft seal helps prevent lubricant migration into the housing, and the shaft end is single-sided. The motor uses size 025 and length code A, which keep the package compact for tightly spaced small-axis layouts.
