Product Description:

The MDD065A-N-040-N2L-095GB0 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a compact motor for digital drive controllers that provides torque to servo axes in automated machining cells, packaging stations, and material-handling equipment. This unit has frame size 065 and motor length code A, so it fits installations that require a short motor body without enlarging the motor envelope. The short housing is useful on machine sections where adjacent components leave limited axial clearance.

The rotor seats into a centering recess that measures 95 mm in diameter, which aligns the motor accurately to the machine interface and helps keep vibration within the standard balancing class. At standstill, the electromagnetic system can maintain a continuous torque of 0.8 Nm, giving closed-loop axes a stable holding force during dwell periods. During motion, the winding design supports a nominal shaft speed of 4000 rpm, matching high-frequency command profiles issued by CNC or PLC controls. Position and velocity data are returned through digital servo feedback (DSF), so the drive controller receives high-resolution signals for field-oriented current regulation. Electrical power and encoder leads exit on Side B through a keyed connector, which simplifies cable routing in tight cabinets.

The rotor is finished to standard balancing quality, which helps reduce bearing load during operation. A plain shaft with a standard end geometry accepts couplings or pulleys, while the front bearing region is protected with a shaft seal to keep splash water and dust away from the lubrication film. Because the motor is supplied without a blocking brake, any required static holding must be handled by an external brake or by servo drive torque. The housing uses a standard ribbed pattern for natural air convection, and the motor has no rear shaft extension, which allows flush mounting against bulkheads or gearboxes.
