Product Description:

The MDD025B-N-100-N2G-040MF0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts the regulated output of an inverter into precise rotary motion for compact automation axes, labeling machines, and electronic assembly stations. Its compact 025 frame and length code B allow installation where space is limited while still supporting fast positioning cycles. In these applications, the motor works with the drive to support accurate starts, stops, and direction changes without requiring a large mounting envelope.

At rated conditions, the motor supplies a continuous standstill torque of 0.60 Nm, allowing it to hold light loads while energized. During operation, it can accelerate the shaft to its nominal speed of 10,000 rpm so that short moves finish quickly. All power and feedback conductors exit on the right side, helping keep cables clear of adjacent machine elements. Position data is delivered through resolver feedback, giving the drive rotor-angle information during rapid reversals and supporting closed-loop servo control. A detachable cable assembly links the motor to the cabinet, and standard balancing helps reduce vibration at high rotational speed.

The mounting interface centers on a 40 mm pilot diameter that aligns the stator to the machine plate. Torque is transmitted by a single keyway shaft, and the standard shaft end omits a side-B extension to conserve depth. For systems that lock motion externally, the unit is supplied without a blocking brake, eliminating brake wear components inside the motor. Quick disconnection is possible through the connecting cable with coupling unit. The standard housing is built without a shaft seal, so the motor is better suited to clean, dry mounting areas than to coolant splash zones.
