Product Description:

The MSK071E-0450-FN-M1-UP0-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Classified as an IndraDyn S synchronous servomotor, it converts commanded current from a drive into rotary motion for positioning tasks in industrial automation. This model follows the standard design, uses winding code 0450, and is built in motor size 071 with the extended E length to provide higher torque within compact machine layouts. A shaft with keyway is supplied for secure mechanical coupling to gearboxes or load shafts, and the motor is well suited to axes that require repeatable motion in limited installation space.

Thermal management is provided by liquid cooling, so heat is removed through an internal coolant jacket rather than ambient air. The feedback head carries a rotatable connector that can turn through 240°, allowing cable exit to be aligned with cabinet routing and reducing bending strain. Position data is exchanged with the drive over the Hiperface serial interface, and the optical scale inside the encoder generates 128 signal periods per mechanical revolution for closed-loop control. The motor housing is rated IP65, which blocks dust ingress and water jets. The motor is supplied without a holding brake, so external holding force is required when the application must keep a load at standstill after power is removed.

The scanning method inside the feedback unit is optical, giving stable accuracy across a broad speed range. The code disc supports a multiturn absolute format, so the controller retains shaft position information after power loss. Rated operation is permitted at ambient temperatures from 0 to 40 °C, and the windings use insulation class 155. This combination supports continuous operation in typical plant conditions while helping the motor handle demanding motion cycles.
