Product Description:
The MSK070D-0450-NN-M1-UP1-NNNN is an IndraDyn S synchronous servomotor from Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop industrial motion axes, this motor converts electrical energy into precise torque and speed for positioning, packaging, or handling stations within an automation line. It is intended for servo applications that require accurate acceleration, controlled deceleration, and repeatable motion during cyclic operation. This operating profile allows the motor to support coordinated machine movements where stable torque response and precise shaft positioning are important.
Its housing is cooled by natural convection, so heat is removed through surface dissipation without fans or external liquid circuits. The mechanical form factor uses size code 070 and length code D, a combination that corresponds to the flange dimensions and stack height available for output torque. A keyed shaft provides positive mechanical locking with couplings, while winding code 0450 identifies the stator winding used in this frame. Electrical terminations include an encoder plug that is rotatable through 240°, allowing the cable exit to be oriented to match cabinet layouts and reduce bending stress. The design is standard, with no special surface treatment or stainless-steel option applied.
Position feedback is supplied through a Hiperface interface that carries both sine-cosine signals and digital memory for parameter storage. The optical scanning head resolves the rotor position into 128 signal periods per mechanical revolution, and the underlying sensing principle is optical, which helps maintain high precision over temperature swings. Multiturn absolute counting tracks revolutions beyond one turn, allowing exact position recovery after power cycling without a reference run. This is useful on axes that must resume operation after a power interruption. Motion can be secured when the line is de-energized because an electrically released holding brake is integrated, and it develops 23 Nm of static torque to keep vertical or loaded axes from drifting.
