Product Description:

The MDD065B-N-040-N2L-095GA1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies rotary motion for positioning axes and speed-regulated spindles in automated machinery. It is suited for applications that require responsive servo control, including packaging equipment, transfer systems, and precision handling axes. The motor has size code 065 and length code B for its frame envelope, and the standard housing allows mounting inside a protected cabinet or on open machine frames.

During continuous stall operation, the motor can supply 1.5 Nm of torque, which indicates how much static load the axis may hold when the shaft is energized but motionless. At its rated electrical frequency, it reaches a nominal speed of 4000 rpm, enabling fast indexing cycles without external gearing. The rotor is dynamically balanced to a standard grade, and a centering diameter of 95 mm positions the flange precisely on a gearbox or machine plate. A plain shaft is supplied in a standard single-ended configuration, so couplings or pulleys seat directly without keyways. A shaft seal is fitted to limit lubricant migration and particle ingress at the bearing interface. The shaft end on side B is omitted, which reduces overall length and simplifies sealing arrangements.

For electrical and feedback attachment, the housing carries a Connector oriented toward Side A, which routes power and encoder leads parallel to the motor axis and helps keep bend radii short inside the cabinet. This arrangement keeps the cable exit concentrated at one end of the motor and supports compact installation layouts. Position information is generated by Digital servo feedback, and this absolute interface closes the velocity and position loops in the associated controller without external sensors. A blocking brake is integrated, delivering 3.0 Nm of holding torque to secure suspended or vertical loads when the drive is disabled.
