Product Description:

The MSK070D-0300-NN-S3-BP0-NNAN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a rotary drive element, it converts controlled stator current into repeatable torque for axes in packaging, handling, and metal-cutting equipment. The unit follows the 070 frame code and D length designation, providing a balanced ratio of power to inertia for mid-size stations. A reduced runout shaft design supports precise positioning when the keyed shaft couples to timing pulleys, gearboxes, or direct-drive load flanges.

The motor relies on natural convection to dissipate heat, so installation must permit free air movement around the housing. Its enclosure carries an IP65 rating, which protects internal components from dust and low-pressure water jets common on factory floors. Continuous duty is specified for ambient conditions from 0 to 40 °C; outside this range, external cooling or derating is required. A shaft with a keyway secures mechanical engagement and helps prevent slippage under dynamic loads. Thermal endurance is governed by insulation class 155, which indicates Class F insulation for the winding system.

Position feedback is exchanged through the Hiperface interface, giving the drive controller both analog sine-cosine and digital identification data. The integrated capacitive sensor resolves each revolution into 16 signal periods, and its single-turn format delivers absolute angular information within one mechanical revolution. Electromagnetic behavior is set by winding code 0300, which establishes the motor’s voltage constant and rated current range. Because the assembly is supplied without a holding brake, applications that require standstill torque during power loss must use an external locking mechanism. All power conductors exit on the B-side connector, simplifying cabinet wiring and minimizing cable bend stress.
