Product Description:

The MDD065B-N-040-N2M-095PB0 is a three-phase AC servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is designed for use with digital drive controllers and is intended for closed-loop motion axes, delivering precise torque and speed to linear or rotary mechanisms in automated assembly, packaging, and material-handling equipment. By integrating directly with drive electronics, the motor converts commanded current into mechanical rotation for repeatable industrial positioning tasks.

With a continuous standstill torque of 1.5 Nm, the motor can hold or slowly index light loads without thermal overload when stationary. Under rated excitation, it reaches a nominal speed of 4000 rpm, giving ample velocity range for pick-and-place heads or belt drives. Precise centering during mounting is supported by a 95 mm centering diameter, while standard dynamic balancing keeps vibration within servo-grade limits throughout the full speed range. Power and feedback conductors terminate on Side B through a sealed connector, simplifying cable routing in compact cabinets. A shaft machined with a keyway transmits torque into pulleys or couplings, and a fitted shaft seal blocks lubricants or contaminants from entering the stator cavity. Only the drive-side shaft is provided, so no extension exists on the opposite end, which reduces overall length and guarding requirements. The housing and overall mechanical envelope follow the standard pattern for the 065 frame size.

Position accuracy is sustained by the integrated multi-turn absolute encoder, which reports rotor angle across multiple revolutions to the drive for homing-free startup. The control loop is closed in real time through digital servo feedback, allowing the controller to regulate flux and torque without external sensors. The stator stack corresponds to length code B, providing additional core material over the shorter variant for greater thermal capacity. Because the unit is supplied without a blocking brake, holding torque must be provided by the drive or an external mechanical lock when power is removed.
