Product Description:

The MSK040C-0450-NN-S1-UG1-NSNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and offered within the MSK IndraDyn S Synchronous Motors series. Serving as a precision drive element, it converts regulated electrical power into tightly controlled rotary motion for industrial automation lines, allowing coordinated positioning and velocity control when paired with compatible drive electronics. The motor uses a plain shaft for direct coupling, which suits assemblies that rely on clamp couplings or other backlash-conscious connections. Its frame size 040 and length code C give it a compact form for smaller axes, and it is available in a version suited to both standard duty and hazardous-area use.

For mechanical protection, the housing has an IP65 rating that keeps out dust and resists low-pressure water jets commonly found on factory floors. Heat generated by the stator windings is removed through natural convection, so the motor does not require forced-air hardware. The feedback system uses Hiperface communication to send single-turn absolute position data to the servo controller over the motor connection. Electrical terminations are easier to route because the encoder connector is rotatable through 240°, allowing the cable to leave in different directions to suit the machine layout. Position information is supported by an internal code wheel that provides 128 signal periods per revolution, helping the drive achieve smooth interpolation during motion.

An electrically released holding brake provides 4 Nm of static torque, which helps keep vertical or suspended axes in place when power is removed. The motor operates within an ambient range of 0 to 40 °C, matching typical industrial enclosure conditions. Feedback stability benefits from the encoder's optical scanning technology, which supports accurate position capture across the motor's operating range. Insulation class 155 allows winding temperatures up to 155 °C, supporting thermal durability during continuous-duty operation.
