Product Description:

The MDD025B-N-100-N2K-040PE1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for operation with digital drive controllers, converting commanded current into controlled rotation for positioning axes in automated assembly and material-handling cells. The unit uses the compact 025 frame size, employs the B length code, carries a standard housing, and is balanced to a standard grade so vibration stays low at speed.

Performance data show how this motor behaves under continuous regulation. A nominal speed of 10000 rpm supports rapid indexing where short cycle times are required. At standstill, it can deliver 0.60 Nm of continuous torque, allowing the axis to hold load without overheating while stationary. Rotor position is provided by an integrated absolute encoder; this encoder supplies multi-turn position data to the controller so homing moves are unnecessary after power-up. For real-time current loops, the drive also reads resolver feedback, giving sinusoidal position signals that allow smooth field-oriented control even at high speed. These electrical features work together with a standard housing that accommodates an internal blocking brake and seals.

The integrated brake supplies 1.0 Nm of holding torque to secure the shaft during powered-off states. A centering pilot of 40 mm aligns the motor on machine plates, while power and feedback are routed through a connecting cable with a coupling unit that exits on the left side of the stator terminal box. The drive shaft is machined with a keyway for positive torque transmission, and it is protected by a shaft seal so lubricant does not migrate from the gearbox into the motor interior. A single-ended shaft arrangement, standard without a side B extension, keeps the overall length short and leaves the rear face clear for mounting encoders and the blocking brake.
