Product Description:

The MDD025B-N-100-N2G-040ME1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Supplied for use with digital drive controllers, it converts bus power into controlled rotary motion for lightweight positioning axes and high-speed tooling heads in automated equipment. Its mechanical interfaces, electrical connections, and thermal layout suit compact installations where limited inertia and fast acceleration are required. The compact format also fits small motion assemblies that need quick response during repeated start-stop cycles.

The rotor is balanced to a standard grade, and a centering diameter of 40 mm guides precise flange seating during assembly. Cables exit on the left side, so control cabinets with lateral trunking can use short cable runs and cleaner routing paths. Continuous standstill output reaches 0.60 Nm, giving small pick-and-place axes enough holding torque while the windings remain within their thermal limit. A blocking brake adds 1.0 Nm of static torque for load retention when power is removed. The winding supports a nominal speed of 10000 rpm, allowing rapid indexing where high rotational velocity is needed. The motor uses a standard housing and a connecting cable with a coupling unit, which helps integrate it into tight machine spaces.

Closed-loop control relies on resolver feedback, which supplies rotor angle and speed signals to the drive. The active length code B pairs with frame size 025 to keep the mass and envelope small for compact linear stages and similar light-duty axes. A keyway shaft end simplifies the attachment of pulleys or miniature gearsets, and the motor is delivered without a shaft seal to reduce drag in dry, clean environments. The absence of a side B shaft end frees installation space at the rear of the motor.
