Product Description:

The MDD025A-N-100-N2G-040PE0 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for use with digital drive controllers, the motor converts regulated electrical input into rotary motion for precise positioning and speed control in compact automation equipment such as indexing units, feed axes, and small handling systems. A resolver mounted in the stator returns position data to the drive for closed-loop operation. Its compact frame is suited to installations where low moving mass and accurate feedback are both important. The standard housing includes a shaft seal that helps keep contaminants away from the bearings when the motor is installed in general machine frames.

Its continuous static torque is 0.33 Nm, so the rotor can hold that load continuously under natural-convection cooling. During operation, the shaft can reach 10,000 rpm, which supports rapid motion in lightweight assemblies. A centering pilot of 40 mm on the flange helps align the motor with adjoining mechanical parts, and all electrical connections exit on the left side to simplify cable routing in confined spaces. Power and feedback are carried through a connecting cable with a coupling unit, and that arrangement allows the cable set to be detached at the motor connection point without opening the housing. The rotor uses standard balancing to help limit vibration at higher speeds. The motor is supplied without a blocking brake, so any power-off holding function must be provided externally.

The housing uses motor size 025 with motor length code A, giving the unit a short and lightweight form that suits small moving axes. Torque is transmitted through a shaft with a keyway, which helps prevent slip when pulleys or gears are mounted to the output end. The shaft end on side B is omitted to reduce overall length. The shaft seal helps retain lubricant whether the motor is mounted horizontally or vertically. The compact outline also leaves more room for adjacent components in tightly packed machine assemblies.
