Product Description:
The MSK076C-0450-NN-S2-UG1-RNNN is a servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it delivers closed-loop torque and position control to automated machinery such as packaging axes, pick-and-place gantries, and printing cylinders. The motor integrates feedback electronics and a mechanical layout aimed at consistent accuracy, which helps maintain stable motion over repeated duty cycles. When paired with a suitable drive, it can respond quickly to changing loads while maintaining smooth positioning and speed control.
Cooling is done by natural convection, so no external fan or liquid circuit is required. The rotor and stator have increased concentricity, which limits radial runout and reduces vibration that could affect encoder accuracy. Position feedback is routed through a rotatable 240° connector and uses the EnDat2.1 interface for digital signal transmission. Inside the encoder, optical scanning provides 2048 signal periods per revolution, supporting fine interpolation for precise velocity and position control. The housing has an IP65 rating, which helps protect internal components from airborne dust and low-pressure water jets.
The motor has size 076 with length designation C, giving it a compact profile for use with gearboxes or direct-drive couplings through a plain shaft. For load holding on vertical axes or parked positions, an electrically released brake provides 11 Nm of static torque when power is removed. Continuous operation is permitted at ambient temperatures from 0 to 40 °C, and operation outside that range requires derating to control winding temperature. The insulation system uses class 155, allowing the winding materials to withstand elevated operating temperatures without damage to the varnish or slot liners. This thermal capacity supports repeated industrial duty when the 0450 winding is operated with the appropriate drive current.
