Product Description:
The MSK071D-0450-NN-M3-UP0-NNNN is a synchronous servo motor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. Supplied in the standard design and built in motor length code D, the unit is intended to deliver controlled torque and precise positioning in industrial automation cells. By interfacing directly with IndraDrive converters, it serves as the electromechanical link between the drive electronics and the mechanical load, converting regulated three-phase power into repeatable rotary motion for packaging, metal-cutting, or material-handling equipment.
The motor relies on natural convection to remove heat, so no external blower or liquid circuit is needed. Size 071 indicates the stator diameter used for this motor and the torque range available for the axis. Electrical properties are matched to drive inverters by winding code 0450, which determines the phase resistance and inductance used for current control. An enclosure rating of IP65 seals the housing against dust ingress and low-pressure water jets, allowing installation outside protected enclosures. For feedback, the drive reads the Hiperface digital interface, providing absolute position data at power-up. The motor can operate in ambient temperatures from 0 °C to 40 °C without derating, and the insulation system is rated to thermal class 155 °C.
Position sensing is generated by a capacitive encoder that offers 16 signal periods per mechanical revolution, and this raw period information is internally interpolated by the drive for finer position resolution. The feedback plug uses a rotatable 240° connector, which lets cables exit in the preferred direction to avoid sharp bends in tight panels. Because the encoder is multiturn absolute, the controller knows shaft angle across several revolutions without a homing routine. The motor is delivered without a holding brake, so static load retention must be managed by the drive or by external mechanics. The shaft has a keyway for torque transmission, and the assembly retains full protection when operated within the stated ambient range.
