Product Description:

The MDD025B-N-100-N2K-040ME1 is a compact permanent-magnet synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for digital drive controllers used on small pick-and-place axes, test stands, and indexing stations in automated equipment. The motor converts commanded current into proportional torque and speed for controlled motion, and its compact format suits installations where mounting space is limited.

Mechanically, the rotor is balanced to the standard grade so vibration remains low during operation. A centering pilot of 40 mm simplifies coaxial mounting to gearheads or flanges. Power and feedback lines exit on the left side of the stator in the left-side connection direction, which helps with cable routing in narrow cabinets when the motor is installed with its single shaft end. At standstill, it can deliver 0.60 Nm of continuous torque, providing sufficient holding force for light loads while staying within the thermal limits of the size-025, length-B frame. During motion, the unit can reach a synchronous speed of 10,000 rpm, supporting rapid positioning cycles when paired with a compatible drive. The standard housing and connecting cable with coupling unit simplify installation and reduce the amount of extra hardware needed at the motor.

For static load retention, an internal blocking brake supplies 1.0 Nm of torque and is released electrically by the drive. Position data is captured by an integrated absolute encoder, while rotor angle tracking is also available through resolver feedback for compatible control loops. The motor is supplied without a shaft seal, so installation should avoid direct coolant or oil exposure. A single keyway on the shaft provides positive engagement with couplings or pulleys, and the shaft end is provided only on side A to minimize overhang and keep the drive end compact.
