Product Description:

The MDD065B-N-040-N2L-095GL1 is a permanent-magnet synchronous motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts commanded current into precise rotary motion for assembly cells, packaging lines, and general material-handling equipment. The motor's compact electromagnetic design supports accurate speed control, repeatable positioning, and stable torque delivery during changing load conditions. Integrated internal feedback components allow the connected drive to monitor operating status continuously and correct motion in real time. This makes the unit suitable for servo applications that require quick response during starts, stops, and short positioning moves.

A centering diameter of 95 mm positions the housing accurately against the machine flange, while standard balancing helps keep vibration controlled during high-speed operation. Power and encoder leads exit on the left side through a sealed connector, reducing cable bend radius in tight enclosures. At standstill, the electromagnetic system can exert 1.5 Nm continuously, and the windings support a rated speed of 4000 rpm without derating. When power is removed, a blocking brake provides 3.0 Nm to hold vertical loads in place. The motor uses a standard aluminum housing for convection cooling, has a plain shaft with a standard shaft end, and does not include a rear secondary shaft, which helps keep the installation length compact.

Position data are returned through digital servo feedback, allowing the drive to determine commutation angle each cycle and maintain accurate speed regulation. An integrated shaft seal helps keep coolant mist and dust out of the bearing chamber when the motor operates near fluids or airborne debris. Size code 065 and length code B give the motor a slim form that fits beside neighboring axes without crowding the machine layout. The plain shaft supports direct coupling to pulleys or gear inputs, and the symmetrical mechanical arrangement helps maintain smooth rotation across the operating range.
