Product Description:

The MSK101D-0450-FN-S1-AP2-NNNN is an IndraDyn S synchronous servomotor in the MSK IndraDyn S Synchronous Motors series manufactured by Bosch Rexroth Indramat. It serves as a drive element in automated machinery, delivering regulated torque and position for axes that perform repeatable motion profiles in packaging, metal-cutting, and handling equipment. By converting controlled current from a Rexroth drive into rotation and returning feedback through its integrated encoder, the motor supports closed-loop motion sequences with high precision. This arrangement allows the drive system to correct speed and position deviations during acceleration, steady travel, and stopping.

This unit is supplied in motor size 101 with length code D, and winding code 0450 matches the electrical characteristics expected by the associated inverter. Because the housing carries the FN requirement, an external circuit passes coolant through the stator jacket; the closed-loop system uses liquid cooling to limit heat rise during continuous operation. An electrically released holding brake supplies 70 Nm, locking the axis when the controller is off and helping prevent unintended movement at standstill. The enclosure has an IP65 rating, which helps protect internal components from dust and low-pressure water jets. Rotor position is transmitted over the Hiperface interface, and the optical sensor provides incremental and absolute data with 128 signal periods per revolution for fine interpolation. This feedback arrangement supports accurate commutation and stable position control across a wide operating range.

For installation, the power connector is on the A-side so cables exit toward the machine frame, and the shaft is a shaft with a keyway for reliable torque transfer. The encoder reports absolute angle within one turn, a feature termed single-turn, which can reduce the need for a reference move on short-stroke axes after startup. Continuous duty is permitted between 0 to 40 °C, and operation outside that range requires derating or additional cooling capacity. Windings use insulation class 155, allowing the motor to withstand higher internal temperatures before insulation aging increases. The A-side connection and keyed shaft make the unit suitable for direct coupling arrangements where secure mechanical engagement and orderly cable routing are required.
