Product Description:
Bosch Rexroth Indramat manufactures the MSK040C-0450-NN-M3-UP0-NNNN. The unit is classified as an IndraDyn S synchronous servomotor and sits within the MSK IndraDyn S Synchronous Motors series. In automated machining centers and pick-and-place gantries, it converts drive current into commanded torque so that linear or rotary axes follow precise position and velocity profiles set by the motion controller. By integrating a high-resolution feedback device and a keyed shaft, the motor provides both electrical and mechanical reference points required for closed-loop industrial automation tasks.
Heat produced in operation is removed by natural convection, eliminating the need for external blowers and allowing the motor to fit compact machine layouts. The housing carries an IP65 protection rating, which prevents dust ingress and guards against water jets during washdown cycles. Position feedback is routed through a Hiperface interface; this serial protocol transmits absolute position and parameter data over two differential pairs. Inside the encoder, the rotor angle is sensed by a capacitive pickup instead of optical glass, increasing shock tolerance. Because the measuring system is multiturn absolute, the drive retains position information over 4096 turns without backup batteries.
The feedback connector can be oriented after installation; it is rotatable through 240°, which eases cable routing in tight enclosures. A resolution of 16 signal periods per mechanical revolution supplies the drive with fine interpolation data for smooth velocity control. Mechanical power is transferred through a shaft with keyway, enabling direct coupling to pulleys or gear wheels while preventing slip under peak torque. The motor is specified for ambient temperatures from 0 to 40 °C, and its C length with winding code 0450 balances thermal mass and electromagnetic density. The 040 frame follows the standard mechanical design and uses Class 155 insulation to withstand continuous thermal stress. The unit comes without a holding brake, so external locking methods are needed for power-off holding.
