Product Description:

Bosch Rexroth Indramat manufactures the MDD065B-N-040-N2L-095GA0, a synchronous motor in the MDD Synchronous Motors series that couples with digital drive controllers to execute closed-loop rotary motion in automated equipment. By supplying commanded current to the stator windings, the drive regulates magnetic torque on the rotor so that the shaft follows programmed speed and position profiles used in pick-and-place axes, packaging spindles, and light conveyor stations. Standard dynamic balancing minimizes vibration during operation. The stator housing is the unventilated standard variant, allowing installation in sealed cabinets.

The motor’s centering diameter is 95 mm, which aligns the flange precisely on machine mounting faces and preserves concentricity with coupled mechanics. At standstill, it can deliver a continuous torque of 1.5 Nm, supporting static holding or low-speed feed duties without overheating. The rated mechanical output reaches 4000 rpm; at this nominal speed, the drive can maintain constant torque while keeping electrical losses within design limits. Power and feedback conductors exit on Side A, simplifying cable routing when the motor is installed against a rear panel, and a single-piece plug-in connector permits quick disconnection during service.

Position information is returned through Digital servo feedback, enabling high-resolution commutation without external encoders. The unit is supplied without a blocking brake, so external locking or active torque from the drive is required for safety stops. Length code B corresponds to the medium stack in the series, while size code 065 identifies the outer frame and bolt pattern. A bonded shaft seal guards the plain output shaft against coolant ingress, and the shaft end follows the series’ standard configuration with no rear extension, reducing the axial envelope when the motor is placed in confined enclosures.
