Product Description:
The MSK040C-0450-NN-S2-UP0-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is intended for industrial automation axes that need accurate torque generation, serving as the electromechanical link between a drive amplifier and the driven machine element. In servo systems, the motor converts controlled current into rotary motion so the axis can follow commanded speed and position values with repeatable accuracy. The compact 040 frame size with C length helps the motor fit tight machine spaces while still supporting the quick response expected in packaging, printing, and material-handling equipment.
Heat is removed through natural convection, eliminating forced-air components and keeping the installation simpler in enclosed machinery. The housing has an IP65 rating, which helps keep dust and water jets away from internal parts during normal operation. Motion feedback is supplied through an optical encoder with the EnDat2.1 interface, giving the connected drive a digital channel for position data. The encoder provides 2048 signal periods and uses single-turn position sensing to report the absolute shaft angle within one revolution. For flexible cable routing, the rear encoder connector is rotatable through 240°, which helps when the motor is installed in crowded machine layouts.
The motor is intended for operation in ambient temperatures from 0 to 40 °C. Torque is transferred through a shaft with a keyway, which provides a positive mechanical connection for couplings, pulleys, or similar drive elements. That shaft style is useful where torque must be transmitted without relying only on clamp friction. Insulation class 155 allows the stator winding to operate at elevated internal temperatures within the limits of the insulation system. The motor is supplied without a holding brake, so any required load holding at standstill must be provided by the axis design or by drive control. Winding code 0450 identifies the electrical setup used for this version.
