Product Description:

The MDD025B-N-100-N2K-040PL0 synchronous motor is manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is a motor for digital drive controllers that supplies precise rotary motion to compact positioning axes in automated assembly stations. The unit’s 025 frame size and B-length body are suited to applications where short overall length and low rotor inertia are required.

A centering pilot of 40 mm sets the mounting interface and keeps the stator concentric with adjacent mechanics. The rotor can reach a nominal speed of 10000 rpm, supporting fast indexing cycles in light-duty actuators. During standstill, it can deliver 0.60 Nm, allowing the drive to maintain position under static load. Power and feedback conductors exit on the left side through a plug-in connector housing, so cables can be routed along machine frames without sharp bends. Motion is transmitted through a shaft with a keyway, which helps prevent relative slip between the motor shaft and the driven hub when acceleration torque peaks occur.

Dynamic feedback is obtained from an integrated absolute encoder that provides multi-turn position data at power-up, while fine velocity regulation is refined by the companion resolver feedback channel inside the same housing. The wiring shell uses a sealed connector type that matches compatible drive controllers and maintains IP protection at the cable entry. The motor has a shaft seal to reduce lubricant migration, and the shaft end is the standard single-sided style so no load is attached on side B. Because the unit is supplied without a blocking brake, external holding devices are required when gravity or overhauling loads are present. The motor uses standard balancing and a standard housing finish, supporting stable operation without additional trimming weights.
