Product Description:
The MSK050C-0300-NN-M3-UG1-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In an automation cell, the motor works with a servo drive to convert commanded current into regulated torque and position for linear guides, rotary tables, and packaging axes. This arrangement supports closed-loop motion where repeatable starts, stops, and indexing moves are required. Its compact housing supports installation in machines that require tight dimensions and accurate dynamic positioning.
This unit uses frame size 050 with length class C, giving it a compact mechanical envelope for mid-range loads. The stator uses winding code 0300, which matches the electrical characteristics expected by compatible IndraDrive controllers. The housing is sealed to IP65, which helps protect internal parts from dust and water jets. Cooling is provided by natural convection, so no external fan is required. Because cooling is passive, the motor can be used where low noise and simple wiring are preferred. A plain shaft transmits torque without keyways, and class 155 insulation supports elevated winding temperatures. The permitted ambient operating range is 0 to 40 °C.
An electrically released brake provides 6 Nm of static holding torque, which helps keep vertical or suspended loads in place when power is removed. Position feedback is transmitted through a Hiperface interface between the drive and the integrated multi-turn absolute encoder. The encoder provides 16 signal periods per revolution and uses capacitive scanning, which is resistant to magnetic interference. Absolute position feedback is available immediately after startup, which reduces the need for a homing routine in many machine designs. The feedback connector can be rotated through 240° to simplify cable routing in confined spaces, and the multi-turn function retains position data across power cycles without batteries.
